CGCS2000大地问题解算工程运用研究

军事信息系统研制中经常涉及CGCS2000坐标系下的大地问题解算,但直接采用韦森特公式进行软件设计存在一些问题。通过对韦森特公式在工程运用中的问题进行了分析,对正解、反解算法进行了补充完善并给出了相关的计算实例供编程检查。改进后的算法简单实用,适合军事信息系统软件的实现。

Rescarch of Engineering Application of Geodesic Calculation Based on CGCS2000 Coordinate System

The geodesic calculation based on the CGCS2000 coordinate system is always referred in the research and development of the military information system. However, directly desingning softwares with the Vicente Formula will result in some problems. According to the analyses of the problems of the Vicente Formula exerted in engineering, this paper improves the normal,inverse solution algorithms and gives out the correlative calculation instances for the programming inspection. The improved algorithms are simple and applied,fits the research and development of the Military Information System well.
