寻北系统陀螺仪与g有关项漂移的场地标定

Calibration of Gyro Drift Related to g Acceleration in the Field

根据寻北系统的工作原理,提出了一种与g有关的陀螺仪漂移误差的场地快速标定方法。通过该方法可以在外场地简便、有效地对寻北陀螺的与g有关的漂移项进行准确测量。通过误差补偿可以保证寻北系统长时期的工作精度。

Based on principle of north finding system, a fast method to calibrate the g related error of gyro drift is proposed. The error can be measured accurately by this way in outside field. North finding system will work normally for long time when the error is compensated.
