结合现行捷联惯测组合标定时间长、操作复杂的实际,针对目前几种捷联惯测组合快速标定方法中存在的问题,提出了一种“12位置+速率”标定的快速标定方法。在粗调平免对北的条件下,将速率标定与位置标定结合进行,大大缩短了标定时间。进行了更为合理的位置编排,使得标定结果精度更接近精确调平对北条件下的标定结果。进行了误差系数分离的推导,并给出了标定流程。采用该方法使得快速标定的精度得到了进一步改善。
Aiming at the problems existing in the rapid calibration methods of several strapdown inertial detection (HIS) combinations, the fast calibration method of “12-position + velocity” calibration . Under the condition of coarse adjustment and avoidance to north, the combination of rate calibration and position calibration greatly shortens the calibration time. A more reasonable position arrangement has been carried out to make the calibration result precision closer to the calibration result under the accurate condition of the north. The derivation of error coefficient separation was carried out and the calibration procedure was given. With this method, the accuracy of rapid calibration is further improved.
