基于解析法的全球定位系统姿态测量技术

提出了一种新的实时全球定位系统（GPS）姿态测量初始化方法，将超越方程的求解与模糊度函数法相结合，有效地提高了初始化计算速度．讨论了模糊度函数法，从几何角度描述了观测方程，给出了二元非线性观测方程组的解，并对实测数据进行了处理．结果表明，该方法与一般的方法相比，初始化的计算更有效，更经济．

A Technique for GPS Attitude Determination Based on Analytical Method

This paper presented a new initialization method of the real-time GPS attitude determination system,which integrates the solution of the transcend equation and the ambiguity function method(AFM),speeds up the calculation of the initialization.This paper also discussed the ambiguity function method,and described the observation functions from the point of view of geometry,and gave the analytical solution of the dual non-linear coupled equation, and dealt with the data collected in the real system.The results demonstrate that the new method is more effective and more economical than the normal method.
