| 摘 要： | 描述一种基于非专用接收机的GPS实时定姿算法,主要工作可以分为两个部分:第一,采用最小二乘方法和乔里斯基分解,基于基线长度约束压缩整周模糊度搜索空间,以达到实时计算的目的;第二,结合姿态角约束,使用金字塔算法提高了整周模糊度求解效率.经过实验,算法在基线长度为3 m的条件下,航向角精度优于0.1°.

| Abstract: | This paper describes algorithms of a real-time attitude system which has been realized by using non-dedicated GPS receivers. The work of the system can be divided into two parts: first, under the constrain of baseline length, we use the LSAST method and Cholesky decompose to reduce ambiguity search space; second, under the constrain of attitude angle, we use the pyramid algorithm to improve the efficiency of ambiguity search under the condition of three meter length baseline, the accuracy of the yaw can reach 0.1. |
