卫星导航观测方程双曲面交会解

本文探索了卫星定位中观测方程的建立方法及求解算法,即探讨了若把卫星定位中的观测方程从求球面方程的交点变换成求双曲面方程的交点后的差异和对定位解的影响.文中结合转发式卫星定位系统的具体应用,提出和推导了转换求解的方法.并通过几何放大因子DOP和测站三维位置坐标单点解分布图的仿真分析,验证了双曲面交会解的可行性,也揭示了其长处和优势.最后,通过对中国区域定位系统CAPS（China Area Positioning System）定位解的实验,证实了观测方程双曲面解的实用性.

Hyperboloidic intersecting solution for navigation measurement equation

This work discusses the establishment and solution of navigation measurement equation, that it the difference and impact on the positioning solution from the intersecting point of spherical equations to the intersecting point of hyperboloidic equations. Transformation solving method has been proposed and derived in combination with the practical application of transmitting the satellite navigation and positioning system. And through the simulation analysis of dilution of precision （DOP） and distribution map of observation station coordinates, the feasibility of hyperboloidic intersecting solution has been verified.Its advantages also have been revealed. Finally, the practical of hyperboloidic intersecting solution has been comfirmed through the experiment of China Area Positioning System.
