An analytical method for real-time GPS attitude determination

A new method of initialization about the real-time GPS attitude determination system is presented. The combination solutions of the dualistic, non-linear equations and the ambiguity function method promote the computation efficiency of the initialization. The paper discusses the ambiguity function method and describes the observation equation in terms of geometry. The analytical solution of the dual non-linear coupled equation is given, and the real-time data are processed. As a result, compared with the normal method, the new method is more effective and economical.
