RS-D2 was a 41.5 kg experimental spin stabilized satellite designed with a power handling capability of 16W .It was launched onboard SLV-3 from SHAR Centre on April 17, 1983. The Smart Sensor Camera was the primary payload onboard the satellite. It has sent more than 5000 pictures frames in both visible and infra-red bands for identification of features and demonstrated the technique of determination of attitude and orbit using images. The camera had on-board processing capability to use the data for classifying ground features like water, vegetation, bare land, clouds and snow.
