A 41.5 kg Rohini satellite launched by SLV-3 in April 1983 whose Smart Sensor camera sent back more than 5,000 picture frames.
Re-entered Earth's atmosphere on 19 April 1990, according to the public satellite catalogue.
The main instrument on RS-D2 was the Smart Sensor camera. It sent back more than 5,000 picture frames in visible and infrared light.
The camera could process its own data on board. It sorted ground features into classes such as water, vegetation, bare land, clouds and snow. The mission also showed that pictures could be used to work out the satellite's attitude and orbit. It carried an L-band beacon as well.
RS-D2 weighed 41.5 kg and could handle 16 watts of power. It was spin-stabilised and used VHF radio.
SLV-3 launched RS-D2 from SHAR Centre, Sriharikota, on 17 April 1983, into an orbit of 371 × 861 km tilted 46°.
The mission lasted 17 months. The satellite stayed in orbit for about seven years and re-entered the atmosphere on 19 April 1990.
