摘要：
We present a correction approach of angular gain based on frequency mismatch of a gyroscope operating in the Whole Angle (WA) mode. The virtual carouseling (VC) and closed-loop WA modes of operation were implemented on a Quad Mass Gyroscope (QMG). The variations in the frequency mismatch associated with the temperature drift were made observable through VC and compensated in the angular gain estimation.
