The initial installation error of inertial navigation systems(INS) can not eliminate, this error will seriously influence the precision of INS. A technology for calibrating the installation of INS based on the GPS location and total station is researched. The technology calculates the angle of plane' s heading and north direction,compares with the indicated data of plane' s INS, achieves the purpose of calibrating the alignment error. Using this technology are tested, the result of test indicates that the technology can quickly calculate the alignment error of the plane, thus repair the output of INS and improve the navigation precision.%针对惯性导航系统的初始安装误差无法消除,且该误差会严重影响试验机的惯性导航系统导航精度的问题,研究了一项结合测绘型GPS和全站仪测量的惯性导航部件安装校准技术,通过GPS定位和全站仪测量并解算出试验机航向和真北方向之间的夹角,与试验机上惯导系统指示数据进行对比,从而达到快速准确校准惯导系统安装误差的目的.运用该技术进行了试验验证,结果表明,该技术可以快速定位惯性导航系统在试验机上的初始安装误差,从而对惯导输出进行补偿,使惯导系统导航精度得以提高.
