自1996年7月以来,DGFI处理南美洲大陆和周边地区永久观测GPS站的所有可用数据,作为IGS区域网络助理分析中心,用于SIRGAS参考系统(IGS RNAAC SIR)。现在大多数RNAAC台站的观测周期足够长,可以求解出可靠的速度。DGFI为ITRF2000提交了DGFIOOP01解决方案。在这里,我们提出了一个新的计算扩展到2001年初的观测。文中着重讨论了潮汐计附近站的垂直运动。
Since July 1996 DGFI processes all the available data of permanently observing GPS stations in the mainland of South America and in the surrounding areas as an IGS Regional Network Associate Analysis Center for the SIRGAS Reference System (IGS RNAAC SIR). The observation periods of most of the RNAAC stations are now long enough to solve for reliable velocities. DGFI submitted its solution DGFIOOP01 for ITRF2000. Here we present a new computation extended to the observations in early 2001. Emphasis is given to the vertical movements of stations near tide gauges.
