3 动态 GPS定位自从利用 GPS载波相位观测的机载动态定位于 1 985年第一次得到证实之后 ,可靠的 GPS解支持航空摄影测量、遥感活动和地球物理测量的能力显著改进了。这些改进来源于若干因素的综合 :第一 ,运动 GPS接收机可以跟踪 8颗或更多颗卫星 ;第二 ,可以得到精密星历供后处理之用 ;第三 ,提出了一些算法 ,它们能以少量的相位和伪距观测量在运动中初置相位偏差。这些因素综合起来 ,产生了精确到厘米级的动态定位能力。这就是动态 GPS定位技术。它可以把距离延伸到约 1 0 0 km。采用 KARS( Kine-matic And Rapid Static)程序…  相似文献

There are three aspects in the study of GPS meteorology network in the Wuhan region. The first is the comparison of the GPS precipitable water vapor between final ephemeris and ultra-rapid ephemeris for which the relative coefficient is 99.97 and the root mean squares is 0.048 mm. It can be concluded that ultra-rapid ephemeris can be used to get the GPS precipitable water vapor for the real-time prediction. The second is the comparison of precipitable water vapor of GPS stations and the distribution of water vapor in the Wuhan region is acquired. The change of GPS precipitable water vapor and rainfall in a rainfall process are compared and analyzed. The change of GPS precipitable water vapor can reflect and predict the process of rainfall.  相似文献

This paper describes the ocean loading tides corrections of GPS stations in Antarctica, such as the Great Wall station and Zhongshan station. Based on the theory of ocean loading tides, the displacement corrections of ocean loading tides on GPS stations in Antarctica are calculated by using the CRS4.0 ocean loading tides model. These corrections are also applied to GPS data processing. The GPS data are analyzed by the GAMIT software with and without these corrections. We compared and analyzed the GPS baseline components to get the differences. The results show that the ocean tidal displacement corrections have obvious effects upon GPS baseline components. Therefore, we should not ignore the ocean loading tides corrections of GPS stations in Antarctica to obtain precise and reliable results.  相似文献
