摘要
本文介绍了上海天文台对苏联发射的两颗地球动力学卫星《Etalon》的观测概况.1990年4月至12月,共获得73圈激光测距资料,其中最多一圈的测距数为4256个,测量距离超过了两万公里.
A summary of the laser ranging tO Etalon geodynamics satellites at Shanghai Observatory, which were launched by USSR in 1989, is presented in this paper. Totally 73 passes have been obtained from April to December, 1990. A maximum of 4256 ranging data has been recorded in one pass. In general those satellites with a range of over 20000km can be easily measured by our laser ranging system.
