| 摘 要： | 研究导航系统定位优化问题,GPS载波相对定位进行载体姿态测量会受到信号传播误差、天线布局、姿态信息解算方法等因素的干扰,从而导致测姿精度下降。为了有效分析各种干扰因素对测姿系统影响程度,采用GPS载波相位双差定位和直接求解姿态矩阵算法,设计了GPS姿态测量分析系统,开发出能综合分析GPS测姿系统性能的分析软件,并通过实例进行了仿真。仿真结果表明,系统能完成GPS测姿系统定位性能优化的有效性。

| Abstract: | The accuracy of GPS attitude determination by carrier phase can be influenced by signal transmitting errors,aerial configurations,attitude calculation errors and other factors.For analyzing the degree of the disturbers in the attitude determination system,this paper designed a GPS determination analytic system based on algorithm of carrier phase differential positioning technique and direct attitude solution method.The whole software frame,the main function and the design method were given,and the software correctness was certified by comparison simulation.Computer simulation shows that this system can analyze the characteristic of GPS determination system effectively. |
