卫星激光测距(SLR)是确定大地测量参考框架,特别是实现全球网的起源和规模的重要技术。SLR导出的参考框架实现的主要限制因素之一是基准精度,其显著地受到当前全球SLR站分布的影响。在本文中,一个潜在的未来发展的SLR网络上估计的基准参数的影响进行了研究。的SLR网络的当前状态进行比较,以模拟潜在的未来网络具有额外的站,改善全球网络的几何形状。此外,还考虑到了可能导致更多观测量的技术进步。因此,我们发现,网络的改进导致网络翻译参数的分散度降低了24%,规模降低了20%,而技术的改进导致翻译参数的分散度降低了27%,规模降低了49%。地球方向参数从这两种效果中受益高达15%。
Satellite laser ranging (SLR) is an important technique that contributes to the determination of terrestrial geodetic reference frames, especially to the realization of the origin and the scale of global networks. One of the major limiting factors of SLR-derived reference frame realizations is the datum accuracy which significantly suffers from the current global SLR station distribution. In this paper, the impact of a potential future development of the SLR network on the estimated datum parameters is investigated. The current status of the SLR network is compared to a simulated potential future network featuring additional stations improving the global network geometry. In addition, possible technical advancements resulting in a higher amount of observations are taken into account as well. As a result, we find that the network improvement causes a decrease in the scatter of the network translation parameters of up to 24%, and up to 20% for the scale, whereas the technological improvement causes a reduction in the scatter of up to 27% for the translations and up to 49% for the scale. The Earth orientation parameters benefit by up to 15% from both effects.
