基于GPS基准站网的GPS测量

采用基于GPS基准网的GPS测量可以提高GPS测量的可靠性和准确性 ,可以消除和减小GPS测量观测值中与时间和空间相关的大气误差和轨道误差的影响 ,使中、长距离快速静态定位和RTK动态定位成为现实 ,还具有可直接得到WGS84Z坐标等优点。本文介绍基于GPS基准站网的GPS测量 ,简要地论述GPS虚拟参考站法VRS和区域改正数法FKP的原理、方法和特点 ,以及目前实施中存在的一些问题

GPS Surveying Based on GPS Reference Station Network

GPS surveying based on GPS reference station network can improve the reliability and veracity, eliminate and weaken the infection of atmosphere error and orbit error which is relative to time and space in the observation of GPS surveying, which makes the rapid static pointing and RTK dynamic pointing of medium and long distance into reality, and has virtues of acquirable WGS84 coordinate directly. GPS surveying based on GPS reference station network is introduced, the theory?method and character is simply discussed of GPS virtual reference station VRS and area correction parameters FKP, some problems which now exists is discussed too during implementing.
