ISRO completes investigation into failure of its SSLV rocket on first launch
India’s space agency ISRO today released the results of its investigation into the launch failure of its SSLV rocket on its first flight in August 2022.
The investigation revealed that there was a vibration disturbance for a short duration on the Equipment Bay (EB) deck during the second stage separation. SSLV is a three-solid-stage launch vehicle unlike the PSLV, which is a four-stage rocket. The vibration affected the Inertial Navigation System (INS), resulting in declaring the sensors faulty by the logic in the Fault Detection & Isolation (FDI) software.
In plain English, it appears the vibration caused a failure in the inertial navigation system, thus resulting in the premature engine shutdown of the fourth stage.
According to the report, the problem has been fixed and the next SSLV launch is now tentatively scheduled for February 9, 2023.
