摘要
GPS测量与数据处理中的精度估算、广播星历和精密星历的获取途径和采用原则、同步环与异步环的检核问题、如何根据GPS高程(大地高)求正常高等问题是发挥好GPS作用的一些关键环节。根据长期GPS应用、研究与总结,提出了一些满足实际工程应用的方法。
How to develop GPS＇ functions shall be based upon precision estimation of GPS survey and data processing, acquisition ways and adopted principle of broadcast ephemeris ＆ precise ephemeris, synchronous ring ＆ asynchronous ring as well as GPS elevation （geodetic height） to seek normal height. Some methods will be set forth to meet the actual technical application in accordance with long term GPS＇ application, research and summary.
