【摘要】：針對高精度大范圍的GPS控制網(wǎng)進行基線解算和平差時,海潮負荷和大氣負荷對地面測站造成的影響最大可達厘米級的問題,闡述了2種負荷的影響原理和各種負荷常用的改正模型;還結合中國陸態(tài)網(wǎng)絡,從短基線、南北方向長基線、東西方向長基線和靠�；€4個方面對比分析了2種負荷對網(wǎng)和測站的綜合影響。結果表明東西方向的基線比南北方向的基線更容易受到2種負荷的影響,且長、短基線受到的影響表現(xiàn)出一定的季節(jié)性變化。為監(jiān)測中國大陸地殼運動、重力場形態(tài)及變化和現(xiàn)代大地測量基準系統(tǒng)的建立和維持提供了參考。
[Abstract]:For the GPS control network with high precision and large range, the maximum influence on the ground station caused by tidal load and atmospheric load can reach centimeter level when the baseline solution is not equal to the difference. This paper expounds the influence principle of two kinds of loads and the correction models of various kinds of loads, and combines with the land state network of China, from the short baseline to the north and south direction long baseline, The combined effects of the two loads on the network and the station are compared and analyzed in four aspects: the long baselines in the east and the west and the baselines in the sea. The results show that the baselines in the east-west direction are more susceptible to the effects of the two loads than the baselines in the north and south directions. The influence of short baselines shows seasonal variation which provides a reference for monitoring crustal movement gravity field shape and variation and the establishment and maintenance of modern geodetic datum system.
