摘要

为了研究低成本GNSS设备监测水平位移的性能，将ANN-MB-GNSS和A10天线安装在蔡司- brt -006还原测量仪上，该测量仪在水平面上的移动灵敏度为mm。用U-Blox-ZED-F9P-02B-GNSS接收机记录10 d静态数据，用CSRS-PPP在线服务进行处理。考虑观测周期(12、6、3、1h)，进行了9次水平位移量级试验。此外，还考虑了GNSS-PPPAR解决百分比、多径和信噪比值。结果表明:采用PPP方法，a10天线3小时观测可确定20mm位移(6mmRMSE);采用UBX天线6小时观测可确定30mm位移(15mmRMSE);

Performance of low-cost GNSS equipment in monitoring of horizontal displacements

To investigate theperformance of low-cost GNSS equipment in monitoring horizontal displacements ANN-MB-GNSS and A10 antenna were installed on Zeiss-BRT-006 reduktionstachymeter, which can move with mm sensitivity in the horizontal plane. Ten days of static data were recorded with U-Blox-ZED-F9P-02B-GNSS receiver and processed with CSRS-PPP online-service. Considering theobservation period(12,6,3,1h), nine horizontal displacement magnitude tests were performed.Inaddition, GNSS-PPPAR solution percentages, multipath and signal-to-noise ratio values were considered. The results reveal that 20mm displacement can be determined (6mmRMSE) using the PPP approach based on a 3-hour observation period with A10antenna and 30mm can be determined (15mmRMSE) with UBX antenna with a 6-hour observation.

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.
