一种基于全站仪的飞机惯导参数原位检测方法

In-situ Detection Method of INS Parameters based on Electric Total Station

通过在飞机机场测定高精度基准点和基准线,利用徕卡全站仪高精度测量能力及可编程性,建立机场区域惯性基准坐标系,分别观测基准点和飞机姿态标志点获取相应的点之间的距离、角度和坐标,并经开发的专用软件计算后获得飞机精确的位置、姿态和航向等信息。同时,利用惯导系统检测仪监测到惯导系统对准完后输出的位置、航向和姿态角等参数,得到飞机工作输出的惯导参数。二者数据进行直接比对,实现飞机在任意停机状态时惯导参数的原位检测。

High precision reference points and lines are established in the airport. And using the programmability of to- tal station, the inertial reference coordinate system can be established. Then the total station observes each reference point and aircraft attitude landmark, and acquires the data. The data is used to calculate the precise information of location, pos- ture and course by software. Meanwhile, the corresponding output of INS is tested by inertial navigation system detector. It is compared with the former to realize situ detection of inertial parameters when a plane stops in the arbitrary condition.
