MICRO-SATELLITE ATTITUDE DETERMINATION USING GPS CARRIER PHASES
-
摘要: GPS姿态系统是利用GPS载波相位测量来确定载体的航向和姿态角.本文对微卫星的GPS姿态系统进行了研究,重点解决短基线的GPS姿态算法;讨论了姿态价格函数的最小化方法.测试结果表明,所提的算法对小于1 m的基线是有效的.Abstract: The GPS carrier phase measurements are used to determine the attitude of a vehicle. A technique based on the attitude cost function is proposed for attitude determination assuming that the cycle integer ambiguities are known. The method that minimizes the cost function is discussed. To verify the method proposed, the experiments have been conducted, and the testing results are given in this paper.
