摘要
三维数字罗盘可以实时输出载体的二维姿态和地理方位角。在差分GPS精密水下立体定位系统中,可以用于GPS浮标姿态测定,进行GPS天线坐标实时三维改正。本文对三维数字罗盘工作原理进行了简要介绍,并针对三维数字罗盘与GPS同步问题进行了详细分析,同时给出了GPS天线坐标改正公式。
Dimentional Digital Compass can output real-time pitch,roll,and heading angle of the carrier.It can be used to provide attitude of GPS-Buoy in Under-water Positioning System which used to calibrate the coordinates of GPS antenna center.In this paper,the basic working mechanism of the 3-Dimentional Digital compass is introduced,and the time synchronization of 3-Dimentional Digital Compass with GPS is given.Moreover,some calibrating formula of GPS coordination are shown in the end.
