The Indian Space Research Organisation (ISRO) on Sunday said the satellites placed on its maiden Small Satellite Launch Vehicle “are no longer usable” as the SSLV-D1 placed them in an elliptical orbit instead of a circular one.
It said failure of a logic to identify a sensor failure and go for a salvage action caused the deviation. The space agency said a committee would analyse and make recommendations into the episode, adding that with the implementation of those recommendations “ISRO will come back soon with SSLV-D2”.
“SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit. Satellites are no longer usable. Issue is reasonably identified,” ISRO said in its latest update on the new mission. It further said a detailed statement by chairman will be shared soon.
