GLONASS与GPS的坐标转换

GLONASS Transition Between GLONASS and GPS

首先介绍了GLONASS系统,随后详细阐述了GLONASS与GPS所采用的坐标系统,推导出PZ-90坐标系与WGS-84坐标系转换的数学模型,重点论述了转换参数的求解,并提出适合于我国范围内的转换公式。论文又从转换公式入手,论述了从WGS-84大地坐标系到WGS-84空间大地坐标系再到PZ-90空间大地坐标系,最后再到PZ-90大地坐标系的转换过程,并完成此项过程的程序设计。最后通过实例讨论了我国范围内从WGS-84到PZ-90的坐标转换。

In this paper, the GLONASS system is introduced, then the coordinates adopted in both GLONASS and GPS are discussed. The authors present a mathematic model of conversion between PZ-90 and WGS-84.This paper lays emphasis on the expounding the solution of converting parameters,then,the converting formula suitable for use in China is also presented. After that, in this paper starting from the converting formula to discuss the WGS-84 ground coordinate system and space-ground coordinate system as well as the PZ-90 space-ground coordinate system and ground coordinate system are discussed.Finally, the data used in China in the process of WGS-84 converting into PZ-90 are analyzed.
