GPS单点定位程序开发几点思考

Thoughts of GPS Single Point Positioning Program Development

GPS单点定位是根据计算出的卫星坐标,再以伪距或者载波相位为观测量,通过空间后方交会原理计算出地面测站点位置。作者利用VB语言对这两个过程进行了实现。本文对此程序的开发过程进行了详细阐述,并总结了程序开发过程中对误差进行处理的方法和一些关键技术问题的解决思路,为进一步开发GPS基线解算程序奠定了基础。

GPS single point positioning that is based on the calculated satellite coordinates pseudo-range or carrier phase which are observed by GPS receiver calculate the coordinates of observation station through the principle of space resection.The two processes are achieved with VB language.In this paper,the process of program development is expounded in detail,the ideas of solving some key technical problem and the right ways of dealing with errors in the process of program development are summarized.This resear...
