摘要
GPS网络RTK技术是20世纪90年代新兴的测量技术,其中内插算法的应用最为广泛。决定内插算法计算结果精度的关键因素就是流动站的定位精度。而影响流动站最终定位精度的因素有很多种,如基准站的布设,基准站点点位坐标的误差等。本文主要讨论了其中的一个重要影响因素——基准站和流动站的相对位置。通过讨论,将给出不同情况下的定位精度,并最终给出了最佳精度的相对位置。
GPS network RTK is a newly developed technique since 1990s, in which the interpolation method is the most widely used technique. The key factor to decide the accuracy of the result is the accuracy of moving station. However, there are many factors that impact on the aeeuracy of moving station, such as the setting of reference stations, the coordinate ＇ s error of the reference stations and so on. This article mainly discusses one of the important factors-the relative location of reference station and moving station. Through the discussion, it finds the different accuracy in different situation. And finally it points out the relative location when the accuracy is the best.
