摘要
随着GNSS的不断发展,市面上出现了越来越多的GNSS接收设备。论文用不同系统的两型接收机在同一位置进行相同时长的静态单点定位实验。对实验结果进行处理,比测两型接收机的定位精度,结果表明多系统的GNSS设备静态定位能力更优。将用Loess局部加权回归法对双系统接收机数据进行预处理后得到的数据结果与原始结果对比,发现精度有所提高,可见Loess预处理有一定提高定位精度的效果。
With the development of GNSS（Global Navigation Satellite System）, there are more and more GNSS receiving devic- es around the market. The article described that the experiment using two GNSS receiving devices with different systems to conduct the PPP experiment in quiescent condition at the same time and same site. It turned out that the receiver with multi-system had bet- ter positioning capacity- in quiescent condition. Comparing original data with the data disposed by Loess method, the result showed that Loess method dealing with the data had good effect and got a better position level.
