摘要
目前卫星激光测距(SLR)中所采用的IRV星历已经使用了近20年,近几年来随着对高轨卫星的测距和卫星白天测距的开展以及考虑到今后激光测距技术的发展,需要对SLR所采用的星历进行改进,以适应SLR发展的需求。从2006年8月起国际激光测距网(ILRS)将使用一种新的可用于多种目标测距的星历——CPF星历,该星历不仅可用于人造卫星的激光测距,而且还可用于月球及其转发器等目标的激光测距。该文介绍了这种SLR新星历和应用它进行卫星位置台站预报的情况,分析了其预报精度。
The Ranging present ＂Tuned IRV＂ ephemeris have been used for nearly 20 years by Satellites Laser stations. Recently with the range to high orbit satellites and the laser ranging on daytime being in progress; and besides, considering the development of SLR technology in the future, the SLR ephemeris should be improved to meet the future development. At the beginning of August of 2006 a new kind of ephemeris, CPF ephemeris, which is adaptive to ranging to kinds of objects will be used by the ILRS. The new ephemeris would be applied not only to SLR, but also ranging to the moon and transponders. This paper introduces this new ephemeris format and applys it to predicting satellitic position and then analyses CPF ephemeris prediction accuracy.
