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 telemetry, oceanography and hydrology. Both satellites are named after ancient Indian mathematicians Bhāskara I and Bhāskara II.[2]
