摘要
介绍在GPS动态RTK测量中 ,WGS -84坐标系和BJ5 4坐标系 ,西安 80坐标系 ,以及地方坐标系之间的转换问题。分析三参数、七参数转换的实质 ,给出了计算公式的详细推导。该文分析了如何在GPS接收机手簿上进行设置 ,怎样实时的获取当地坐标的工作原理 ,通过以上公式和原理编写了求七参数和三参数的应用软件 ,便于工作中的应用 。
Conversion problem between WGS-84?BJ54?Xi-an80 coordinate and local coordinate systems in GPS dynamic RTK surveying are introduced in the paper. We gave the detail deduction of the calculation formula through analyzing the conversion reality of three parameters and seven parameters. The paper analysed how to set up on the GPS receiver electronic book and the work principles of how to obtain the local coordinate on realtime. Based on the above formula and principles,an application program of three parameters and seven parameters is made in order to have convenient application in our work and also an useful tool to analyse the system errors of control network based on different coordinate systems is provi ded.
