舰载GPS航姿测量中卫星位置的计算与最优星座的选取

Computation of Satellite Position and Selection of Optimal Constellation in Determination of Ship's Attitude and Heading using GPS

该文给出了在GPS航姿测量算法研究中的卫星位置计算的整个过程 ,数据处理采用RINEX标准输入格式 ,所得结果形象直观 ,便于分析。在此基础上提出了一种选择最优星座的方法。作为试验算例 。

In research of algorithm of ships attitude and heading determination using GPS,the computation of satellite position is crucial for calculation of attitude and heading.In this paper a total computing process is given,and the RINEX standard input format is used in data processing.The result is visual,intuitionistic and easy to analyze.Based on aforementioned,a method of selecting the optimal constellation is presented.As a test example,the selection result based on broadcast ephemeris is shown at the end. of the paper.
