摘要
随着科学技术的迅猛发展,现今的天体力学和天体测量已经发生了日新月异的变化.人类已经能够近距离探测太阳系内的一些天体,精度也达到了前所未有的程度.例如,激光测月(LLR)的精度已经达到了3mm,正在向1mm迈进;激光测卫(SLR),如激光地球动力学卫星(LAGEOS)的测轨精度已经达到了0.5mas;甚长基线干涉测量(VLBI)的精度已经好于0.1mas;对于未来的两个空间探测计划,全天天体测量干涉仪(GAIA)和空间干涉测量任务(SIM)都有望达到μas的精度.
With the development of the unprecedented techniques for observation and the improvement of the advanced methods for measurement, it is time for astrometry to unfold a new era indubitably. Presently, the satellite laser ranging like LAser GEOdynamics Satellite (LAGEOS) has achieved a precision of 0.5 mas for orbit determination, the precision of Lunar Laser Ranging (LLR) has approached one millimeter,
