摘要
差分GPS水下立体定位系统通过将差分GPS定位技术和水下声学定位技术进行集成,实现高精度水下定位。本文基于差分GPS水下立体定位系统的基本观测方程,简要介绍了迭代法的基本原理,从双曲线差分定位观测方程出发,使用求解非线性方程组常用的牛顿迭代法构造迭代方程式,并用实测数据验证了该算法的可行性。
By integration of DGPS and acoustics positioning technique, under-water DGPS system implements high accuracy under-water positioning. In this paper, the principle of iterative algorithm is introduced briefly. Then, iterative equation is set up with Newton-iterative method according to hyperbolic positioning equation of under-water DGPS. In the end, the iterative algorithm is proved to be feasible with real observation data.
