A New Systematic Calibration Method for SINS

A new systematic calibration method is proposed based on the strapdown inertial navigation equation. The disadvantage of static position systematic calibration and the traditional rotate-hold systematic calibration is analyzed. Combined the advantages of both the two method, a systematic calibration method of “position + rotate-hold” is designed. The method simplifies the calibration process by data multiplexing and combined the two experiments into a common experimental procedure. The reliability of the method is verified by the calibration simulation. The method is simple and feasible, and can be applied to the outfield calibration of the SINS.
