摘要
本文介绍了日本发射的测地卫星及广州、上海对它的观测.用本文计算卫星轨道的方法,发现该卫星的轨道比原计划要低得多,而其他轨道根数正常,并对其原因作了探讨.本文认为,该卫星的闪光方式可以提高卫星的瞬时亮度,但宜缩小卫星的直径,以减少大气和光压摄动以及卫星质心改正,提高激光测距精度.
The geodetic satellite launched by Japan as observed from Guangzhou and Shanghai is discussed. Obital determination shows that the actual orbit of this
Satellite is much lower than designed orbit, but other orbital data are normal. This paper offers an explanation. The flash model of the satellite increases its instantaneous brightness. But this kind of satellite should be smaller in diameter so as to decrease the air and radian pressure perturbations as well as error in correcting the mass-center and increase the accuracy of laser-ranging.
