RS D1 [ISRO]
The third and fourth satellites in the Rohini program, called RS D1 and D2 (Rohini satellite) were small satellites to test simple earth observation payload.
The spin-stabilized 35 kg satellites featured launch earth observation instruments and were powered by body monted solar cells.
RS D1 featured a remote sensing payload called Landmark Tracker. Due to too low orbit, the satellite reentered premature after only 9 days.
RS D2 had a Smart sensor remote sensing payload, which had both visible and infra-red capabilites. The mission operated for 17 months.
