Indian Science Policy

Indian Science Policy outline in the form of a resolution passed in 1958 to secure for the people of India and the benefits from the acquisition of scientific knowledge and its application.

Following the recommendation of the Sarkar Committee,the Government established five Indian Institutes of Technology at Khragpur,Mumbai,and Delhi within a decade.

The IITs are premier institutions for technological research in India and work in close consultation with industry.

Indian Nuclear Policy

Nuclear Energy must be used for peaceful purpose.

Nuclear weapons must be eliminated all over the world.

India will not even undertake peaceful expositions unless it is absolutely necessary.

India will keep her nuclear options open and will not sign the Nuclear None Proliferation Treaty so long as it is discriminatory.

Indian Space Achievements

There have been several achievements over the last two decades with the launching of Aryabhatta on April 19,1975.

Till end 2010 ,53 satellite have been launched.

At these satellite were designed and fabricated in India.

Remote Sensing

Remote Sensing is a method of recording information without actual contact with the object or area being investigated.

Remote sensing uses the visual infrared and microwave portions of the electro-magnetic spectrum.

Status of Remote Sensing in India

In India the National Remote Sensing Agency(NRSA) is located at Hydrabad.

Its regional centres at Dehradhun,Bangalore,Nagpur,Khoragpur and Jodhpur utilise modern remote-sensing techniques for assistance in the planning and management of country's natural resources.

The IRS data from these are being used in :

AGRICULTURE -area and production,data collection,pest disease surveillance.

FORESTRY AND HYDROLOGY - mapping of forests and water resources including channel shifting of Brahamputra.

LAND USE - land cover mapping in urban and rural areas.

Land degradation and desertification studies.

Wastelands , waterlands and wastage zone mapping and soil mapping

Indian Defence Policy

Indian Defence Policy aims at promoting and sustaining durable peace in the subcontinent and equipping the defence forces adequately to safeguard aggression.

India's Missile Programme

An Integrated Guided Missile Development Programme was launched by India in 1983.It comprise following missiles developed by DRDO.

TRISHUL : It is short range surface to air missile having a range of 500 metre to 9 km.

AKASH : It is a medium range ,surface to air missile having a range of 25 km.

AGNI-I and AGNI-II : In order to strengthen the Indian Armed Forces.India once more tested its indigenous made missile.

Agni-II missile from Chandpur in Balsaore ,Orissa , successfully launched on January 25 2002,Agni-I and Agni-II with range of 1500 km and 2000 km respectively.

DHANUSH : It is a naval version of Prithvi missile.Dhanush can strike surface to surface up to 150 to 300 nautical miles.

NAG : It is a third generation fire and forget anti tank guided missile having a range of 4 km.

MBT-ARJUN : It is India's main battle Tank(MBT),indigenously designed and developed by DRDO and Combat Vehicle Research Development Establishment (CVRDE),Avadi.

The Arjun weight 58 tones and hence falls in main battle tank category (above 50 tones)

LAKSHYA : The Pilotless Target Aircraft (PTA) Lakshya is a sophisticated unmanned aircraft.

Pinaka : To build up ground support for Indian Army,It is amobile weapon system characterised by capability to fire up to 12 rockets within a second.

Nishan : Earlier called Falcon,is India's indigenous Remotely Piloted Vehicle (RPV).

It can carry a 45 kg payload travel at a speed of 150 kmph and fly for more than five hour.
