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, 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:
