Bhaskara-I, weighing 444 kg at launch, was launched on 7 June 1979 from Kapustin Yaraboard 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] The satellite consisted of-

Two television cameras operating in visible (600 nanometre) and near-infrared (800 nanometre) and collected data related tohydrologyforestry 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. 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.
