7个天文台站人卫经纬仪静态系统差的检测

Detecting the Static Systematic Errors of Satellite Theodolites in Seven Astronomical Observations of Stations

给出了中国科学院７ 个天文台站经纬仪静态系统差的测算结果。根据经纬仪的光学和机械构造， 提出一种有１０ 个误差参数的经纬仪静态系统差模型。又根据星表中的恒星沿赤经基本均匀分布的特点， 提出一种快速查找指定恒星的方法。对于《中国天文年历》中所载的１２１８ 颗恒星的星表， 使用这种快速查找方法， 平均只需查找４ 次即可。

The results to detect the static systematic errors of satellite theodolites in seven astronomical observations or stations,Chinese Academy of Sciences,have been given in this paper.According to the structure on optics and mechanism of theodolites,a model with 10 error parameters for static systematic errors of theodolites is proposed.Further,a method for fast searching appointed stars is derived.
