摘要

连续运行参考站（CORS）网络提供测量、测绘和定位服务，在确定地壳位移方面发挥着至关重要的作用。本研究处理了从越南TAST CORS的55个CORS站收集的连续全球导航卫星系统（GNSS）数据，以确定2018年至2021年越南的地壳位移。使用在线精确点定位（PPP）服务和位移模型进行处理，以估计位置时间序列的速度。结果表明，在2014年国际地面参考框架（ITRF2014）中，所有CORS站的水平速度场在大小和方向上都是均匀的，在东南方向的精度为±0.1至±1.0mm/年，范围为25.3至42.6mm/年。这项研究证实了TAST CORS网络用于地壳位移分析的GNSS数据的稳定性和准确性。

Crustal displacement in Vietnam using CORS data during 2018 - 2021

Continuously Operation Reference Stations (CORS) networks provide surveying, mapping, and positioning services and play a crucial role in determining crustal displacement. This study processed the continuous Global Navigation Satellite System (GNSS) data collected from 55 CORS stations in the TAST’s CORS in Vietnam to determine the crustal displacement in Vietnam from 2018 to 2021. The processing was performed using online Precise Point Positioning (PPP) services and the displacement model to estimate the velocity of the position time series. The result showed that the horizontal velocity field of all CORS stations is uniform in magnitude and direction, ranging from 25.3 to 42.6 mm/year with accuracy from ±0.1 to ±1.0 mm/year in the south-east direction in the International Terrestrial Reference Frame 2014 (ITRF2014). This study confirms the stability and accuracy of GNSS data from the TAST’s CORS network for crustal displacement analysis.
