山东区域海潮负荷对GPS高精度测量的影响
The effects of Shandong regional ocean loading on GPS high precision surveying
摘要
Abstract
The ocean loading effects on GPS and GPS baselines are calculated by using the FES2004,CSR4.0 and NAO99b ocean models based on the baseline information of SDCORS website data.In terms of GPS positioning,the results show that the ocean loading effects on coastal areas are greater than the inland areas about 3 cm,and the influence of vertical direction is the greatest one which is 2-3 times as large as the east-west and north-south direction;in terms of GPS baselines,ocean loading effects on SDCORS baselines are related to the length and station position,and have obvious periodicity.It could not be ignored in the coastal area GPS high accu-racy surveying .In addition,the NAO99b model is the most suitable model for GPS high accuracy surveying in Shandong area based on the calculation results of the three kinds of tidal model con-trast analysis.关键词
