Abstract

This study investigates the accuracy of vertical displacements monitored by Global Navigation Satellite Systems (GNSS) precise point positioning (PPP) with float-ambiguity solution and with ambiguity resolution (PPP-AR). For this purpose, a simulation was designed. The static GNSS observations were collected at a test point during different observation times over seven periods involving vertical displacements produced with a precision of less than one mm. Each set of GNSS observations was processed with both GNSS-PPP and PPP-AR methods. The results revealed that RMS values of PPP-AR solutions are about twice better than RMS values of PPP solution for all observation times and all vertical displacement values.

GNSS-PPP和PPP-AR方法确定垂直位移的定位性能

本研究探讨了全球导航卫星系统(GNSS)精确点定位(PPP)监测垂直位移的精度，该定位采用浮动模糊解决方案和模糊解决方案(PPP- ar)。为此，设计了仿真程序。静态GNSS观测数据在7个周期的不同观测时间内在一个测试点收集，垂直位移精度小于1 mm。每组GNSS观测数据分别使用GNSS- ppp和PPP-AR方法进行处理。结果表明，在所有观测时间和所有垂直位移值下，PPP- ar方案的均方根值比PPP方案的均方根值好2倍左右。

期刊介绍： Survey Review is an international journal that has been published since 1931, until recently under the auspices of the Commonwealth Association of Surveying and Land Economy (CASLE). The journal is now published for Survey Review Ltd and brings together research, theory and practice of positioning and measurement, engineering surveying, cadastre and land management, and spatial information management. All papers are peer reviewed and are drawn from an international community, including government, private industry and academia. Survey Review is invaluable to practitioners, academics, researchers and students who are anxious to maintain their currency of knowledge in a rapidly developing field.
