Abstract: A system for protecting a pendulous oscillating gyroscopic accelerometer (POGA) from power failure interruption (PFI) events, the POGA having a servo driven member (SDM), rotor driven member (RDM), and torque summing member (TSM), wherein the POGA is a part of an accelerometer system of a guidance system which detects such events and communicates them to the accelerometer system. In the invention, the acceleration is stored just prior to the PFI induced system shut-down, and after the PFI the POGA drives are turned back on. The velocity change during the PFI is determined based on the TSM deflection occurring during the PFI event, acceleration existing at the beginning, and elapsed time. This is reported to the guidance system in a timely fashion.
