摘要
本文列出了1990年度上海天文台人卫激光观测的测距结果和对测距系统所作的一些改进。
The SLR system at Shanghai Observatory has been improved in 1990. The Z-80 CPU computer has been replaced with an IBM PC/XT-286 computer system. The softwares for prediction and real time display have been renewed. The total 437 passes and 143136 observations are obtained (See Table 1, Table 2 and Table 3). Etalon-1 and Etalon-2 have been observed since April 1990, and the maximum range is over 20000 km. The range accuracy is about 3-4 cm. Several satellite passes in the twilight have been successfully tracked.
