The Bhaskara-I and II Satellites were two satellites built by the Indian Space Research Organisation that formed India's first low orbit Earth Observation Satellite. They collected data on telemetry, oceanography and hydrology.

Bhaskara-I[edit]

Bhaskara-I, weighing 444 kg at launch, was launched on 7 June 1979 from Kapustin Yar aboard the Intercosmos launch vehicle. It was placed in an orbital Perigee and Apogee of 394 km and 399 km at an inclination of 50.7°.[2] It orbited at 519 x 541 km. The satellite consisted of-

  • Satellite microwave radiometer (SAMIR) operating at 19 and 22 GHz for study of ocean-state, water vapour, liquid water content in the atmosphere, etc.

Bhaskara-II[edit]

Bhaskara-II
Mission type Experimental Remote Sensing
Earth Obsservation Satellite
Mission duration 10 years (Re-Entered in 1991)
Spacecraft properties
Spacecraft type Unmanned
Manufacturer ISRO
Launch mass 444 kilograms (979 lb)
Power 47 watts
Start of mission
Launch date November 20, 1981 (1981-11-20Z) IST
Rocket C-1 Intercosmos Launch Vehicle
Launch site Volgograd Launch Station

The satellite provided ocean and land surface data. It orbited at 541 x 557 km with inclination of 50.7°. One of two onboard cameras malfunctioned, however it sent back more than two thousand images. Housekeeping telemetry was received until re-entry in 1991.[3]
