摘　　要：在水下差分GPS定位中,星形空间网具有良好的图形强度,可以快速得到一定精度的初始坐标解。本文研究了水下差分GPS定位模型及其算法,并提出了一种系统差自修正迭代算法,以提高水下定位的可靠性。In practice, it is proved that Star Three-dimensional Network structure has a good character of anti-jamming and avoids appearing ill-conditioned design matrix,so the initial solutions of undetermined coordinate can be determined quickly,and the solutions will be steady and accurate when using the optimized space network design. For the high-precision positioning, studying the algorithm of Underwater DGPS is necessary, and therefore the algorithm of systematic error correction was given in this paper.
