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, 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°. The satellite consisted of-
- Two television cameras operating in visible (600 nanometre) and near-infrared (800 nanometre) and collected data related to hydrology, forestry and geology.
- Satellite microwave radiometer (SAMIR) operating at 19 and 22 GHz for study of ocean-state, water vapour, liquid water content in the atmosphere, etc.
The satellite provided ocean and land surface data. One of two onboard cameras malfunctioned, however it sent back more than two thousand images. Housekeeping telemetry was received until re-entry in 1991.
