海潮负荷对江苏CORS高精度测量的影响
Influence of Ocean Tide Loading on JSCORS High Accuracy Surveying
摘要
Abstract
Jiangsu Continuously Operating Reference Station(JSCORS)is one of Jiangsu digital infrastructures, which can provide compositive information services of high precision, efficiency and resolution. Ocean tide loading is one of errors influencing JSCORS high precise surveying and has been studied here. Results got by CRS4.0 and FES2004 ocean tide mode indicated that the influence of ocean tide loading to X and Z direction was less than Y direction, and the influence value was relational with place of sation and length of baseline. Difference of correction between two ocean tide modes was different, that was to say, it was 1 mm for X direction, 0. 5 mm for Y direction, 0. 2 mm for Z direction. Undoutedly, it was indispensable to consider the influence of ocean tide loading on JSCORS high precise surveying.关键词
