CHENNAI: Isro will launch the second developmental flight of the Small Satellite Launch Vehicle (SSLV) from Satish Dhawan Space Centre in Sriharikota at 9.18am on Friday (February 10).
SSLV-D2/EOS-07 would carry three payloads, including earth observation satellite EOS-07, Isro said. EOS-07, which will be the primary payload, is in the 200kg small satellite class. Two more payloads, including Janus-1 from US firm Antaris, will also be flown.
SSLV, in its maiden flight in August, failed to place the satellite in a desired orbit. Isro conducted a failure analysis. The agency, on its website, said, “Subsequent detailed analysis of the flight events and observations ranging from countdown, lift-off, propulsion performance, stage separations and satellite injection revealed that there was a vibration disturbance for a short duration on the Equipment Bay (EB) deck during the second stage (SS2) separation, that affected the Inertial Navigation System (INS), resulting in declaring the sensors faulty by the logic in Fault Detection & Isolation (FDI) software.”
“Considering the clear identification of the cause of the flight anomaly and suggested corrective actions, the next development flight (SSLV-D2) is planned to be executed complying to the recommendations, its satisfactory implementation, review and approval by the authorized committees,” the agency said.
