BLITS卫星 (Ball Lens In The Space)

 

2009年9月17日发射,轨道倾角98.77度,高度832公里,太阳同步轨道.重7.53公斤.

圆形轨道,周期101.3分钟.

直径85.13mm,内部的球形反射器直径53.52mm.只有SLR技术可以对其进行POD

(Precision Orbit Determination ).

任务的目的是试验和验证球状玻璃回射器的卫星之概念和获取SLR数据,解决地球

物理学地球动力学和毫米级相对论以及亚毫米级精度的SLR测量等科学问题.

"The purpose of the mission is experimental verification of the spherical glass retroreflector satellite concept as well as obtaining SLR data for solution of scientific problems in geophysics, geodynamics, and relativity by millimeter and submillimeter accuracy SLR measurements."---1

格拉茨卫星激光测距站,用重复率2千赫兹的激光确定了BLITS的旋转参数,发表了论文.---2

"The 2 kHz SLR station Graz measures spin parameters of this satellite, providing information about the rotational dynamics of the body. The measurements obtained during the period from September 26, 2009 to November 24, 2010 show a significant change of the spin configuration"---2
