摘要
本文分析了依巴谷空间天体测量卫星主探测器析像管和恒星测绘仪的工作缺点;介绍了用CCD作为HIPPARCOS主探测器的优越性,预期的观测结果,以及误差分析比较。
The defects of main detector, Imange Dissector Tube (IDT), in HIPPARCOS Space Astrometry Satellite are discussed.The performance of CCD as a main detector in new HIPPARCOS mission is given in detail. We have estimated the expected results and errors in determination of astrometry parameters.
