According to [[S. Somanath]], an anomaly lasting 2 seconds in one of the accelerometers during second stage separation initiated salvage mode by onboard computer. [[Guidance, navigation, and control]] software switched from 'closed loop guidance' where it received real-time feedback from all sensors to an 'open loop guidance' where accelerometer data gets isolated and a predetermined path is followed.<ref>{{Cite news |last=Subramanian |first=T. s |date=2022-08-11 |title=ISRO chief S.
