Temperature characterization test can be carried out on MEMS gyro to obtain the modal resonant frequency and quality factor of MEMS gyro with temperature change relationship curve, so as to give the segmented temperature compensation method. Zero bias measurement during startup; zero bias measurement at different temperatures; measurement of MEMS gyro error caused by temperature change; zero measurement at different temperatures after taking temperature compensation measures; comprehensive test and evaluation report can be provided.
