GENERAL STUDIES

The thrust of the Scientific Policy Resolution, 1958 was on capacity-building in advancement of science as the foundation for making a strong nation, which had just freed itself from the shackles of colonial domination . The focus of the Technology Policy Statement, 1983 was attainment of technological self-reliance and building of national strength by reducing vulnerability in strategic areas .

The Science and Technology Policy, 2003 launched a massive programme for attracting our best talents to the arena of research in basic sciences, so that India continues to earn respect in a competitive knowledge society.

The Science, Technology and Innovation Policy (STIP), 2013 has put our science, technology an innovation (STI) system as the driver for faster, sustainable and inclusive growth .

The latest policy envisages creation of a new STI ecosystem, which finds solutions to societal problems and facilitates the entire innovation chain from knowledge to wealth creation, while at the same time attracting best students to this area, ensuring a premier position for India in the scientific world.

Investments in Science and Technology

• Global investments in science, technology and innovation are estimated at $1.2 trillion as of 2009. India’s R&D investment is less than 2.5% of this and is currently under 1 % of the GDP.
• Increasing Gross Expenditure in Research and Development (GERD) to 2% of the GDP has been a national goal for some time.
• Achieving this in the next five years is realizable if the private sector raises its R&D investment to at least match the public sector R&D investment from the current ratio of around 1 :3. The new paradigm is “Science technology and innovation for the people”.

Position in Research Publications

• The gross budgetary support for the science and technology sector has significantly increased during the last decade. The impact of such increase is becoming evident.
• India ranks ninth globally in the number of scientific publications and 12th in the number of patents filed. The Composite Annual Growth Rate (CAGR) of Indian publications is around 12±1% and India’s global share has increased from 1.8% in 2001 to 3.5% in 2011.
• But the percentage of Indian publications in the top 1 % impact making journals is only 2.5%.
• By 2020, the global share of publications must double and the number of papers in the top 1 % journals must quadruple from the current levels.

 

 Key Elements:

• Promoting the spread of scientific temper amongst all sections of society.
• Enhancing skill for applications of science among the young from all social strata.
• Making careers in science, research and innovation attractive enough for talented and bright minds.
• Establishing world class infrastructure for R&D for gaining global leadership in some select frontier areas of science.

• Seeding S&T-based high-risk innovations through new mechanisms.
• Fostering resource-optimized, cost-effective innovations across size and technology domains.
• Triggering changes in the mindset and value systems to recognize, respect and reward performances which create wealth from S& T derived knowledge.
• Creating a robust national innovation system

Focus of the Policy

• Facilitating private sector investment in R&D centres in India and overseas.
• Promoting establishment of large R&D facilities in PPP mode with provisions for benefits sharing.
• Permitting multi stakeholders participation in the Indian R&D system.
• Treating R&D in the private sector at par with public institutions for availing public funds. Bench marking of R&D funding mechanisms and patterns globally.
• Modifying IPR policy to provide for marching rights for social good when supported by public funds and for co-sharing IPRs generated under PPP.
• Launching newer mechanisms for nurturing Technology Business Incubators (TBls) and science-led entrepreneurship.
• Providing incentives for commercialization of innovations with focus on green manufacturing Important Observations Policy places greater thrust on innovation, establishing research institutes and encourage women scientists with an aim to position itself among the top five scientific powers in the world by 2020.
• It talks about modifying the intellectual property regime to provide for marching rights for social good when supported by public funds and co-sharing of patents generated in the public private partnership mode.
• Aims at producing and nurturing talent in science, to stimulate research in universities, to develop young leaders in the field of science and to reward performance.
• Seeks to create a policy environment for greater private sector participation in research and innovation and to forge international alliances and collaborations to meet the national agenda.
• Talks of raising gross expenditure in R&D to two per cent of GDP from the current one per cent in this decade by encouraging enhanced private sector contribution.
• Seeks to trigger an ecosystem for innovative abilities to flourish by leveraging partnerships among diverse stakeholders and by encouraging and facilitating enterprises to invest in innovations.

 Criticism:

The policy hardly describes any structural or procedural changes which will achieve the grand goal of integrating science, technology and innovation to create value in an inclusive manner.

 

Application of Satellites for different purposes

 

Despite being a developing economy with its attendant problems, India has effectively developed space technology and has applied it successfully for its rapid development and today is offering a variety of space services globally.

Indian Space Program:

During the formative decade of 1960s, space research was conducted by India mainly with the help of sounding rockets. The Indian Space Research Organisation (ISRO) was formed in 1969. Space research activities were provided additional fillip with the formation of the Space Commission and the Department of Space by the government of India in 1972. And, ISRO was brought under the Department of Space in the same year.

In the history of the Indian space programme, 70s were the era of Experimentation during which experimental satellite programmes like Aryabhatta, Bhaskara, Rohini and Apple were conducted. The success of those programmes, led to era of operationalisation in 80s during which operational satellite programmes like INSAT and IRS came into being. Today, INSAT and IRS are the major programmes of ISRO.

For launching its spacecraft indigenously, India is having a robust launch vehicle programme, which has matured to the state of offering launch services to the outside world. Antrix, the commercial arm of the Department of Space, is marketing India’s space services globally. Fruitful co-operation with other space faring nations, international bodies and the developing world is one of the main characteristics of India’s space programme.

The most significant milestone of the Indian Space Programme during the year 2005-2006 was the successful launch of PSLV-C6. On 5 May 2005, the ninth flight of Polar Satellite Launch Vehicle (PSLV-C6) from Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota successfully placed two satellites – the 1560 kg CARTOSTAR-1 and 42 kg HAMSAT – into a predetermined polar Sun Synchronous Orbit (SSO). Coming after seven launch successes in a row, the success of PSLV-C6 further demonstrated the reliability of PSLV and its capability to place payloads weighing up to 1600 kg satellites into a 600 km high polar SSO.

The successful launch of INSAT-4A, the heaviest and most powerful satellite built by India so far; on 22 December 2005 was the other major event of the year 2005-06. INSAT-4A is capable of providing Direct-To-Home (DTH) television broadcasting services.

Besides, the setting up of the second cluster of nine Village Resource Centres (VRCs) was an important ongoing initiative of the Department of Space during the year. VRC concept integrates the capabilities of communications and earth observation satellites to provide a variety of information emanating from space systems and other IT tools to address the changing and critical needs of rural communities.

In October 2008, the first lunar mission launched by ISRO. The spacecraft, Chandrayaan took off from the Satish Dhawan Space Centre and it operated till August 2009. The project was announced by former PM Atal Bihari Vajpayee, as part of his independence day speech in 2003. The greatest achievement of this lunar project was the discovery of a large number of water molecules in moon. ISRO plans to launch its second lunar mission, Chandrayaan 2 by 2018.

In 2014, Mangalyaan, India’s first interplanetary mission was launched, making ISRO the fourth space agency to reach Mars. Mangalyaan gained worldwide repute as being the least expensive Mars mission till date.

Recently India has launched 104 staellites at one go, which is a world record. The previous world record is with the Russian space agency with 37 satellites at one go.

India has been launching heavy satellites on its Geosynchronous Satellite Launch Vehicle (GSLV) but so far it has only been used for domestic satellites.In recent months though, there have been queries from foreign companies for launches on the GSLV.

 

Application of satellites for different purposes:

Satellites based on application can be categorized as follows:

Earth Observation satellite->

Starting with IRS-1A in 1988, ISRO has launched many operational remote sensing satellites. Today, India has one of the largest constellations of remote sensing satellites in operation. Currently, *thirteen* operational satellites are in Sun-synchronous orbit – RESOURCESAT-1, 2, 2A CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2, Megha-Tropiques, SARAL and SCATSAT-1, and *four* in Geostationary orbit- INSAT-3D, Kalpana & INSAT 3A, INSAT -3DR. Varieties of instruments have been flown onboard these satellites to provide necessary data in a diversified spatial, spectral and temporal resolutions to cater to different user requirements in the country and for global usage. The data from these satellites are used for several applications covering agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management.

Communication satellite->

The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in Asia-Pacific region with nine operational communication satellites placed in Geo-stationary orbit. Established in 1983 with commissioning of INSAT-1B, it initiated a major revolution in India’s communications sector and sustained the same later. GSAT-18 joins the constellation of INSAT System consisting 14 operational satellites, namely – INSAT-3A, 3C, 4A, 4B, 4CR, 3DR and GSAT-6, 7, 8, 10, 12, 14, 15 and 16.

The INSAT system with more than 200 transponders in the C, Extended C and Ku-bands provides services to telecommunications, television broadcasting, satellite newsgathering, societal applications, weather forecasting, disaster warning and Search and Rescue operations.

 

Navigation satellite->

Satellite Navigation service is an emerging satellite based system with commercial and strategic applications. ISRO is committed to provide the satellite based Navigation services to meet the emerging demands of the Civil Aviation requirements and to meet the user requirements of the positioning, navigation and timing based on the independent satellite navigation system. To meet the Civil Aviation requirements, ISRO is working jointly with Airport Authority of India (AAI) in establishing the GPS Aided Geo Augmented Navigation (GAGAN) system. To meet the user requirements of the positioning, navigation and timing services based on the indigenous system, ISRO is establishing a regional satellite navigation system called Indian Regional Navigation Satellite System (IRNSS).

(a) GPS Aided GEO Augmented Navigation (GAGAN):

This is a Satellite Based Augmentation System (SBAS) implemented jointly with Airport Authority of India (AAI). The main objectives of GAGAN are to provide Satellite-based Navigation services with accuracy and integrity required for civil aviation applications and to provide better Air Traffic Management over Indian Airspace. The system will be interoperable with other international SBAS systems and provide seamless navigation across regional boundaries. The GAGAN Signal-In-Space (SIS) is available through GSAT-8 and GSAT-10.

(b) Indian Regional Navigation Satellite System (IRNSS) : NavIC

This is an independent Indian Satellite based positioning system for critical National applications. The main objective is to provide Reliable Position, Navigation and Timing services over India and its neighbourhood, to provide fairly good accuracy to the user. The IRNSS will provide basically two types of services

Standard Positioning Service (SPS)

Restricted Service (RS)

Space Segment consists of seven satellites, three satellites in GEO stationary orbit (GEO) and four satellites in Geo Synchronous Orbit (GSO) orbit with inclination of 29° to the equatorial plane. This constellation of seven satellites was named as “NavIC” (Navigation Indian Constellation) by the Honourable Prime Minister of India, Mr. Narendra Modi and dedicated to the Nation on the occasion of successful launch of IRNSS-1G, the seventh and last satellite of NavIC. All the satellites will be visible at all times in the Indian region. All the seven Satellites of NavIC, namely, IRNSS-1A, 1B, 1C, ID,1E, 1F and 1G were successfully launched on July 02, 2013, Apr 04, 2014, Oct 16, 2014, Mar 28, 2015, Jan 20, 2016, Mar 10, 2016 and Apr 28, 2016 respectively and all are functioning satisfactorily from their designated orbital positions.

Ground Segment is responsible for the maintenance and operation of the IRNSS constellation. It provides the monitoring of the constellation status, computation of the orbital and clock parameters and navigation data uploading. The Ground segment comprises of TTC & Uplinking Stations, Spacecraft Control Centre, IRNSS Timing Centre, CDMA Ranging Stations, Navigation Control Centre and Data Communication Links. Space segment is compatible with single frequency receiver for Standard Positioning Service (SPS), dual frequency receiver for both SPS & RS service and a multi mode receiver compatible with other GNSS providers.

 

Experimental satellite->

ISRO has launched many small satellites mainly for the experimental purposes. This experiment include Remote Sensing, Atmospheric Studies, Payload Development, Orbit Controls, recovery technology etc. Example- INS-1A, INS-1B, YOUTHSAT, APPLE

 

Small satellite->

The small satellite project is envisaged to provide platform for stand-alone payloads for earth imaging and science missions within a quick turn around time. For making the versatile platform for different kinds of payloads, two kinds of buses have been configured and developed.

Indian Mini Satellite -1 (IMS-1): IMS-1 bus has been developed as a versatile bus of 100 kg class which includes a payload capability of around 30 kg. The bus has been developed using various miniaturization techniques. The first mission of the IMS-1 series was launched successfully on April 28th 2008 as a co-passenger along with Cartosat 2A. Youthsat is second mission in this series and was launched successfully along with Resourcesat 2 on  20th April 2011.

Indian Mini Satellite -2 (IMS-2) Bus: IMS-2 Bus is evolved as a standard bus of 400 kg class which includes a payload capability of around 200kg. IMS-2 development is an important milestone as it is envisaged to be a work horse for different types of remote sensing applications. The first mission of IMS-2 is SARAL.  SARAL is a co-operative mission between ISRO and CNES with payloads from CNES and spacecraft bus from ISRO.

 

Student/Academic satellite->

ISRO has influenced educational institutions by its activities like making satellites for communication, remote sensing and astronomy. The launch of Chandrayaan-1 increased the interest of universities and institutions towards making experimental student satellites.

 

Chhatrapati Shivaji Maharaj (Shivaji Shahaji Bhosale) was the founder of strong Maratha Empire in the west part of India in 17th Century.

Chhatrapati Shivaji Maharaj (Shivaji Shahaji Bhosale) was born in the fort of Shivneri, near from city Junner (Pune District), in the year 1630 (19th February’ 1630). His mother Jijabai Bhosale named him Shivaji in the honor of goddess Shivai Devi. Chhatrapati Shivaji was devotAed to his mother Jijabai Bhosale, who was extreme religious. This kind of environment had put deep impact on Shivaji maharaj.

Expansion of Empire and Battles of Shivaji

• In the 1659 Adilshah sent Afzalkhan with the army of 75000 soldiers to destroy Shivaji with his empire. Chhatrapati Shivaji killed Afzal Khan with full diplomatically. He signaled his troops to start the great assault on the Adilshahi Sultanate.
• Shivaji defeated Kaltalf Khan, a sardar of Shahista Khan in the Battle of Umberkhind with few soldiers (Mavale).
• Aurangjeb sent his maternal uncle Shahista Khan with powerful army over 1,50,000 on request of Badibegum Sahiba, Adishahi sultanate. In the April 1663Chhatrapati Shivaji personally made surprise attack on Shahista Khan in the LalMahal Pune.
• Chhatrapati Shivaji sacked surat ,the wealthy city of mughal empire in 1664. Surat was the financial capital of mughal& trading centre.
• Chhatrapati Shivaji agreed to give 23 forts and Rs. 4,00,000/- hone, to let his son Sambhaji become Mughal Sardar and ready to meet with Aurangjeb in the treaty of Purander between Chhatrapati Shivaji and Mirza Raje Jaisingh on behalf of Mughal.
• Chhatrapati Shivaji gained lot of province till jinji in Karnataka after coronation in the period of 1677-1678.
• Aurangjeb invited Chhatrapati Shivaji to Agra on occasion of his 50th birth anniversary. However, in the court on 1666 Aurangjeb made in stand behind military commanders of his court.Shivaji got angry and he refused gift which offered by Aurangjeb and stormed out of the court. He was house arrested by Aurangjeb .Chhatrapati Shivaji made supreme plan and succeed to escape from Agra.

Ashtpradhans of Shivaji

It was dministrative and advisory council set up by the Indian Shivaji which contributed to his successful military attacks on the Muslim Mughal Empire and to the good government of the territory over which he established his rule.

• Peshwa- Prime Minister
• Amatya- Finance Department
• Sachiv- Home Secretary
• Sumant- Foreign Secretary
• Nyayadheesh- Judicial Magistarate
• Senapati- Commander In chief
• Panditrao- relifious matters
• Mantri- Day to day activities

Revenue Administration

T he assessment of revenue was made after a careful survey and classification of the lands according to their quality and yield. The share of the state was fixed at two-fifths of the gross produce. The cultivator was given the option of paying either in cash or kind.

Besides the land revenue, Shivaji had other sources of income, of which the most important were the chauth and sardeshmukhi. The chauth amounted to one-fourth of the standard revenue assessment of the place, while the sardeshmukhi was an additional levy of 10 per cent de­manded from areas outside his kingdom because he claimed to be the hereditary sardeshmukh (chief headman) of the entire Maratha country. These taxes were levied on those living outside Maratha kingdom as a safeguard (a kind of protection money) against Shivaji’s forces plundering or raiding their territory.

Marathas Consolidation and Northward Expansion

Age of Peshwas

Balaji Vishwanath

With Balaji Vishwanath in charge of the Maratha military and Kanhoji in charge of the Marathas Navy. This agreement set the course for Balaji Viswanatha’s rise as a Peshwa during his subsequent visit to Delhi with an army of 12,000 Marathas. During this visit to Delhi, on an invitation from the Syed brothers in their struggle with the Mughal Emperor Farrukhsiyyar, the Maratha forces led by Balaji Viswanath clashed with the forces of Mughal Emperor and defeated them. This was the first Maratha victory over the Mughals in Delhi. This event marks the asendency of the Marathas in Delhi an asendency that was to last for almost a century till they were supplanted by the British in 1803.

The Peshwas – Baji Rao, Balaji Baji Rao, Madha Rao
After Shahu, the de facto executive power passed into the hands of the hereditary Prime Ministers the Peshwas. Balaji Viawanath Bhatt was succeeded by his son Baji Rao the first. Baji Rao was a very able and ambitious soldier and he was the one who consolidated Maratha power in North India.

Baji Rao died at a relativey young age of 40 in the year 1740. His was succeeded by his son Balaji Baji Rao. Balaji Baji Rao played a tragic role in Maratha history and the fissiparous tendencies he let loose ultimately let to the downfall of the Maratha empire.
His first mistake was to go back on the agreement between his grandfather Balaji Viswanath Bhatt and Kanhoji Angre according to which the Peshwa was to have no direct control over the Maratha Navy. He attacked the his own navy and weakened one arm of the Maratha might.
During his rule, North India was invaded by Ahmed Shah Abdali first in 1756. Balaji Baji Rao then sent his brother Raghunath Rao along with Malharrao Holkar to defeat Abdali. Raghunath rao not only defeated Abdali but chased him up to the Khyber pass till Attock in Paktoonistan. .
This success of Raghunath Rao aroused the jealousy of Balaji Baji Rao’s wife Gopikabai, who started conspiring against Raghunath Rao to undermine his influence. This led to corresponding jealousy from Anandibai who was Ragunath Rao’s wife. The unfortunate fallout of this court intrigue ws to end in the disastrous 3rd battle of Panipat in 1761.

The 3rd Battle of Panipat
When Abdali launched his second invasion in 1759 the Marathas who after their successes in 1756 had been hibernating in Maharashtra and Central India again woke up and in alliance with the Jat King Suraj Mal of Bharatpur formed an alliance. This alliance led by Shrimant Sadshiv Rao Bhau and Shrimant Vishwas Rao (the Peshwa Shrimant Balaji Baji Rao’s son) won spectacular victories and captured Delhi and Kunjapura (where the Afghan treasury and armoury was located). Here the alliance developed cracks due to the Maratha insistence on not allowing the Jats to loot Delhi. This ultimately split the alliance and Suraj Mal withdrew from the alliance. The Marathas consequently marched upto Panipat, but instead of continuing their attacks to completely defeat the partly defeated Abdali and Najib Khan, they stayed put at Panipat, blocking the way of the Afghans back to Afghanistan. Seeing their way back to their homeland blocked, the Afghans now became restless. They in turn, decided to block the way of the Marathas back into the Deccan.
This stand-off continued for one whole year from the 14th of January 1760 up to the 14th of January 1761. This led to the fall in the morale of the stranded Marathas and ultimatley led to their defeat at Panipat.

The Afghans with Najib Khan meanwhile also recaptured Delhi and Kunjpura. On the decisive day of 14th January 1761 (Makar Sankranti), the Marathas decided to break-through the Afghan blockade and re-enter Deccan. The disastrous battle saw about one hundred thousand Maratha troops being slaughtered in a matter of eight hours. But the Afghans too suffered heavy losses and decided enough was enough and went back to Afghanistan never to return to India.
The defeat of the Marathas and the withdrawal of the Afghans created a power vacuum in North India in the period 1761-1790. It was this vacuum that was filled up by the rising British power. But more of this later.

Formation of Linguistic States:–

India is a land of many languages, each with its distinct script, grammar, vocabulary and literary tradition. In 1917, the Congress Party had committed itself to the creation of linguistic provinces in a Free India. After Congress’s Nagpur Session in 1920, the principle was extended and formalized with the creation of provincial Congress Committee by linguistic zones.

The linguistic reorganization of the Congress was encouraged and supported by Mahatma Gandhi. After the bitter partition on the basis of religion the then PM Nehru was apprehensive of dividing country further on the basis of language.

Dhar commission

During that time some Marathi speaking Congress members raised the pitches for separate Maharashtra State. Following this demand, other language speaking people too demands a separate state for them. Hence, Constituent Assembly in 1948 appointed the Linguistic Provinces Commission, headed by Justice S.K. Dhar, to enquire into the desirability of linguistic provinces.

The Dhar Commission advised against this at that time reason being it might threaten national unity and also be administratively inconvenient.

JVP Committee

After some time the clamor for linguistic states again got momentum. To appease the vocal votaries of linguistic states, the congress appoints a committee (JVP) in December 1948 consisting of Nehru, Sardar Patel and Pattabhi Sitaramayya to examine the question afresh. This JVP Committee revoked the seal of approval that the congress has once put on the principle of linguistic provinces.

The demands for separate state on the linguistic basis didn’t subside. There were renewed movements aimed at linguistic autonomy in 1948, 1949. There was the campaign for Samyukta Karnataka, uniting Kannada speaking spread across the states of Madras, Mysore, Bombay, Hyderabad, Samyukta Maharashtra, Maha Gujarat movement. In case of Punjab, struggle brought together both the factors language and religion (Sikh).

Andhra Movement

After Independence, the speakers of Telugu asked the congress to implement its old resolution in favour of linguistic states.

On 19 October 1952, a popular freedom fighter, Potti Sriramulu undertook a fast unto death over the demand for a separate Andhra and expired after fifty-eight days. After his death people were agitated and it was followed by rioting, demonstrations, hartals and violence all over Andhra. The Vishalandhra movement (as the movement for a separate Andhra was called) turned violent. Finally, the then PM, Nehru announced the formation of a separate Andhra State in December 1952.

State Reorganization Commission

The formation of Andhra Pradesh spurred the struggle for making of other states on linguistic lines in other parts of the country.

Hence Nehru appointed in August 1953 the states Reorganisation Commission (SRC) with justice Fazl Ali, K.M. Panikkar and Hridaynath Kunzru as members, to examine “objectively and dispassionately” the entire question of the reorganization of the states of the Union. The SRC submitted its report in October 1955. It recognized for the most part on the linguistic principle and recommended redrawing of state boundaries on that basis.

The then government accepted the SRC’s recommendations. Finally, the states Reorganization Act was passed by parliament in November 1956. It provided for fourteen states and six centrally administered territories. SRC opposed the splitting of Bombay & Punjab.

Case of Bombay

Therefore, the strongest reaction against SRC’s report came from Maharashtra, where widespread rioting took place. To fulfill their demand of separate Marathi speaking people’s state, there was the broad based Samyukta Maharashtra Samiti and on the other hand in Bombay state, there was Maha Gujarat Janata Parishad led the movement for Gujarati people.

After on years of the reorganization of states Act, the government finally agreed in May 1960, the bifurcate the state of Bombay into Maharashtra, Gujarat with Bombay city being included in Maharashtra and Ahmedabad being made the capital of Gujarat.

Case of Punjab

The other state where an exception was made to the linguistic principle was Punjab. In 1956, the state of PEPSU had been merged with Punjab, which remained a trilingual state having three language speakers-Punjab, Hindu and Pahari within its border. In the Punjabi speaking part of the state, there was a strong demand for carving out a separate Punjabi Suba (Punjabi Speaking State). This demand got communal overtones. The Akali Dal led Sikh Communalists, while the Jan Sangh, led Hindu communalists.

SRC had rejected the demands in Punjab, as it would not solve either the language or the communal problem of Punjab. Finally in 1966, Indira Gandhi agreed to the division of Punjab into two Punjabi and Hindi speaking status of Punjab and Haryana, with the Pahari speaking district of Kangra and a port of the Hoshiarpur district being merged with HP.

Finally, after more than ten years of continuous strife and popular struggles, the linguistic reorganization of India was largely completed

 

Rajrishitulyakul

Rajrishitulyakul dynasty ruled over the south Kaushal. They ruled from 5^th to 6^th century AD. From the bronze inscription it is known that they followed Guptsamvata. This shows that accepted the supremacy of the Gupta Dynasty.

There are six known rulers of the Rajrishikulya Dynasty. They are all follows:

1. Sur
2. Dayit I
3. Vibhishan
4. Buimsen I
5. Dayitverman II
6. Bhimesen II

 

Nal Dynasty

NalDyansty ruled over the south Kaushal in the present day Bastar area. They ruled from 5^th to 12^th century. From the Rajim Inscription it is known that was the founder of NalDyansty.

Nal dynasty ruler Bhavdatverman and Skanda vermin has made Pushkari the capital city.

Vilas Tung was the ruler of Nal Dynasty, he made the Rajiv Lochan temple.

Nals were the contemporary of Vakatakas and Bastar was the centre of their power. Nal lost their power after defeating from Somvanshis.

 

Sharabpuriya Dynasty

It was established in 6^th century. Sharabh, the father of Narendra has established this dynasty.

Sharbhpur was the capital of this dynasty, which is near to Sirpur(Raipur district). There are two bronze inscription in Pipardula(Sanrangarh) and second Kurud(Raipur). These two inscription writes about Narendra’s kindness and his donation to poor. There is another ruler from this dynasty, Prashanna, who started gold coins and established Prashanapur near the banks of river Nidila. Sharbhpur, Shripur and Prashanpaur are written in bronze inscription. Sudevraj established Shripur. In 6^th century Sharabpuriya dynasty came to known as Amaryakul dynasty.

 

 

Pandu Dynasty

 

The first ruler of this dynasty was Udayan. Other rulers are Indrabal, Ishandev, Rankemedi and Bhavdev.

Tivardev made Pandu dynasty a strong kingdom. He was the follower of Shaivism. He adopted Kosalapati title after winning over Kaushal, Utkal and some other Mandals.

Mahanabhdev was the son of Tivardev. He started calling himself as somvanshis. In various inscription it could easily be seen. They patronized all the religions including Buddhists. Many scripture and Viharas are found recently found in recent historical search. Four Bronze inscription of Ballarjuna have been found from bardula, Lodhia, Mallar and Bonda.

 

 

Somvanshi

 

Somvanshiruled in south Kaushal from 9^th to 11^th century.

They considered themselves as the rulers of Kaushal, Utkal and Kalinga. They have adopted Trikalingadhipati title as well.

In their coin image of Rajlakskmi could be seen easily.

The prominent rulers of this dynasty are Shivgupta, Mahashivgupta, Bhimrath II, Dharmaratha, Nahutha, Yayati and Chandihar. Kalchuris continuously attacked on their kingdom. This has shaken their kingdom.

Agni V, believed to be an upgraded version of the Agni III The inter-continental ballistic missile  have a range of about 5000-6000 km . Agni V will be able to carry multiple warheads and would also display countermeasures against anti-ballistic missile systems.

 

Trishul

Trishul is the name of a short range surface-to-air missile developed by India as a part of the Integrated Guided Missile Development Program. It has a range of 9 km and is fitted with a 5.5 kg warhead. Designed to be used against low-level (sea skimming) targets at short range, the system has been developed to defend naval vessels against missiles and also as a short-range surface-to-air missile on land.

 

Akash

Akash is a medium range surface-to-air missile developed as part of India’s Integrated Guided Missile Development Programme to achieve self-sufficiency in the area of surface-to-air missiles. It is the most expensive missile project ever undertaken by the Union government in the 20th century.

 

Nag

Nag is India’s third generation “Fire-and-forget” anti-tank missile. It is an all weather, top attack missile with a range of 3 to 7 km.

 

Other Missiles

Significant additions also include

 

PINAKA– the Multi-Barrel Rocket System , an area weapon system to supplement the existing artillery gun at ranges beyond 30 km, having quick reaction time and high rate of fire has been accepted by the user after extensive trials.

 

BrahMos-  being jointly developed with Russia, is a supersonic cruise missile that can be launched from submarines, ships, aircraft or land.

BrahMos is among the fastest supersonic cruise missiles in the world, at speeds ranging between Mach 2.5 to 2.8, being about three and a half times faster than the American subsonic Tomahawk cruise missile. Although BrahMos is primarily an anti-ship missile, it is also capable of engaging land-based targets.

 

Nirbhay- cruise missile  was announced in 2007—a subsonic missile with a range of 1000 km. Capable of being launched from multiple platforms on land, sea and air. Nirbhay will supplement BrahMos in the sense that it would enable delivery of warheads farther than the 300 km range of BrahMos.

In 2008, New Delhi announced the end of the IGMDP with the focus now shifting towards serial production of missiles developed under this programme.

 

Shaurya– a landbased variant of the K-15 Sagarika which can be stored in underground silos for longer time and can be launched using gas canisters as booster was successfully test-fired in November 2008. This nuclear-capable missile aims to enhance India’s second-strike Sagarika missile is being integrated with India’s nuclearpowered Arihant class submarine that began sea trials in July 2009.

 

Dhanush– which has been tested several times in recent years believed to be a short-range, sea-based, liquid-propellant ballistic missile—perhaps a naval variant of the Prithvi series, with a maximum range of approximately 300 km.

 

Air-to-air missile Astra– It is an air to air missile Beyond Range (BVR). This is the first indigenous air-to-air missile developed by India. The range of this missile is 80 km in head-on chase and 15 km in tail chase.

 

Ballistic Missile Defence system

Two interceptor missiles, the Prithivi air defence missile and the Advanced Air Defence (Ashwin) missile are designed to provide a high-low cover against incoming ballistic missiles. Prithivi is reported to be capable of intercepting missiles at exo-atmospheric altitudes of 50 – 80km, while the AAD is designed to operate at endo-atmospheric altitudes of upto 30kms.

 

It would be apposite to conclude by stating that India’s missile programme represents an iconic image demonstrating sovereignty and self-reliance vis-à-vis its technological achievements. Resultant of nearly three decades of research, India’s guided missile programme has assumed a self-sustaining character and become fundamentally crucial to New Delhi’s proposed minimal deterrent.
