| 摘 要： | 针对测量船惯导系统水平及航向精度检测需求,提出了采用卡尔曼滤波技术解算惯导水平偏差的新方法。对经纬仪校准惯导的基本原理及陀螺的随机飘移分析,利用经纬仪测星方法,在惯导飘移误差小于7′,标定误差可在2″以内,可有效地消除惯导的随机游动误差分量,将使测量船的整体测量精度得到显著的提高。

| Abstract: | In order to satisfy the need of testing the attitude and course of INS of measurement ship, the paper proposes a new method of using the Kalmen Filter to work out the attitude and course error. Analyzing the fundamental of INS calibration by theodolite and random wave of top. The calibrating attitude and course error of INS would deduce random wave error, so as to increase the measuring precision of the ship. |
