中文说明：GPS精密单点定位简称PPP技术，是最近几年各位学者专家研究的比较热门的一个方向，本程序主要在matlab的仿真环境下，实现静态单点定位，采用精密星历，插值运算，对静态目标实现了10米左右的定位。
English Description：
Technology of GPS precise point positioning referred to as PPP, scholars study the question in recent years one of the most popular directions under this program in MATLAB simulation environment, static point positioning using precise ephemeris interpolation arithmetic, for static targets to achieve a position of about 10 meters.
