INDIAN SPACE MISSION Ananth.H.sankar , 2 nd CSC


INTRODUCTION The Indian Space Research Organisation is the primary body for space research under the control of the government of India. It was established in its modern form in 1969 as a result of coordinated efforts initiated earlier.


GOALS AND OBJECTIVES The prime objective of ISRO is to develop space technology and its application to various national tasks. The Indian space program was driven by the vision of Dr Vikram Sarabhai, considered as the father of Indian Space Programme.


LAUNCH VEHICLES Satellite Launch Vehicle(SLV) Augmented Satellite Launch Vehicle(ASLV) Polar Satellite Launch Vehicle(PSLV) Geosynchronous Satellite Launch Vehicle(GSLV)

Satellite Launch Vehicle(SLV):

Satellite Launch Vehicle(SLV) SLV or SLV-3 was a 4-stage solid-fuel light launcher. It was intended to reach a height of 500 km and carry a payload of 40 kg.

Augmented Satellite Launch Vehicle(ASLV):

Augmented Satellite Launch Vehicle(ASLV) ASLV was a 5-stage solid propellant rocket with the capability of placing a 150 kg satellite into LEO. This project was started to develop technologies needed for a payload to be placed into a geo- stationary orbit.

Polar Satellite Launch Vehicle(PSLV):

Polar Satellite Launch Vehicle(PSLV) PSLV is an expendable launch system. It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun synchro- nous orbit. PSLV can also launch small satellites into geostationary transfer orbit (GTO).

Geosynchronous SLV:

Geosynchronous SLV GSLV is an expendable launch system. It was developed to enable India to launch its INSAT-type satellites into geostationary orbit and to make India less dependent on foreign rockets.


COMMUNICATION SATELLITES A communications satellite is an artificial satellite stationed in space for the purposes of telecommunications. For fixed services, communications satellites provide a microwave radio relay technology complementary to that of submarine communication cables. They are also used for mobile applications.


EXTRA-TERRESTRIAL EXPLORATIONS India's first mission beyond Earth orbit was Chandrayaan-1, a lunar spacecraft which successfully entered the lunar orbit on November 8 , 2008. It carries high-resolution remote sensing e q uipment for visible, near infrared, and soft and hard X - Ray frequencies.


VISION FOR FUTURE ISRO plans to launch a number of new-generation Earth Observation Satellites in the near future. It will also undertake the development of new launch vehicles and spacecraft. ISRO has stated that it will send unmanned missions to Mars and Near-Earth Objects.


IRNSS The Indian Regional Navigational Satellite System (IRNSS) is an autonomous regional satellite navigation system. Navigation Satellite Systems like GPS are not guaranteed in hostile situations.


REUSABLE LAUNCH VEHICLE The development of RLVs is driven by the desire to reduce launch costs. No true orbital reusable launch system is currently in use. The orbiter, which includes the main engines, and the two solid rocket boosters, are reused after several months of refitting work for each launch. The external fuel drop tank is discarded.


APPLICATIONS Land and water resources management. Natural disaster forecasting. Radio networking. Weather forecasting. Meteorological imaging and computer communication. Business, administrative services, and schemes such as the National Informatics Centre (NICNET) are direct beneficiaries of applied satellite technology.


CONCLUSION India uses its satellites communication network is one of the largest in the world ISRO has helped implement India's Biodiversity Information System. ISRO has been successful mainly in developing satellites, launch vehicles, Sounding rockets and associated ground systems.
