Bhaskara-I and -II were two satellites built by the Indian Space Research Organisation that formed India's first low-Earth orbit Earth observation satellite. They collected data on oceanography and hydrology. The satellites are named after the ancient Indian mathematicians Bhāskara I and Bhāskara II.[2]

Bhaskara-I

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°.[3] The satellite consisted of:

Bhaskara-II
Mission Type:Experimental Remote Sensing
Earth Observation Satellite
Mission Duration:10 years (Re-Entered in 1991)[4]
Spacecraft Type:Uncrewed
Manufacturer:ISRO
Launch Mass:444kg (979lb)
Power:47 watts
Launch Date: IST
Launch Rocket:C-1 Intercosmos Launch Vehicle
Launch Site:Volgograd Launch Station

Bhaskara-II

The satellite provided ocean and land surface data. It orbited at 541 × 557 km with an inclination of 50.7°.While one of two onboard cameras malfunctioned, the satellite still sent back more than two thousand images. Housekeeping telemetry was received until re-entry in 1991.[5]
