摘要
分析和实现了基于单基线的GPS实时姿态测量系统。通过对姿态参数的精度分析,得出了姿态测量精度同基线长度和相对精度因子的关系;分析了姿态测量系统中单点定位对相对定位精度的影响;最后对姿态测量系统的实时性和姿态测量的结果进行了分析。本文的研究对GPS姿态测量技术的工程应用和理论研究具有一定的参考价值。
GPS-based single baseline real-time attitude determination system is analyzed in this paper. The relationship between the accuracy of attitude parameters and baseline length as well as the relative dilution of precision is derived firstly, then the impact of the stand-alone position on accuracy of relative position is analyzed too. In the end, the real-time process ability and the result of attitude determination are presented. The research work in this paper is considered to be valuable in the project application and the theoretical research of GPS-based attitude determination.
