摘要
The integer ambiguity resolution is the key to precise attitude determination. In case of single frequency single epoch, this paper presents a fast integer ambiguity resolution method based on nonlinear constrained integer least-squares solved with the quadratic eigenvalue problem, and applies it to BDS attitude determination system. The method will integrate the baseline length called the priori information into objective function, and construct new objective function to improve the accuracy of integer ambiguity solution. The effectiveness of the proposed method is verified by experiments on the BDS attitude determination platform. The results show that, in the single frequency single epoch BDS attitude determination, the method has highly improved the success rate of integer ambiguity and attitude determination resolution. © 2017, Chinese Institute of Electronics.
