摘　　要：提出了一种在不具备精确标定设备的试验条件下,分析动基座传递对准精度的工程方法。基于传递对准的安装误差角滤波估计结果,修正子惯导的初始姿态,并重新进行子惯导的导航解算。通过比较初始姿态修正前后子惯导的导航误差,分析对传递对准的精度。对试验数据的处理结果表明:用该法进行子惯导的导航解算,所得速度和位置精度大幅提高。A kind of precision analyzing method for alignment of inertia navigation system （INS） on moving base was presented for the test situation that the equipments for precise calibration of established angles were limited or absent in this paper. The compensation for established angles was utilized to correct the initial navigation errors of sub INS. The navigation arithmetic was made again. The accuracy of the alignment was analyzed by comparing the navigation error between the inertia attitude amended and non-amended. The results of the test data processing showed that the computation speed and precision of position were improved greatly by this method.
