随着千赫兹(k Hz)卫星激光测距技术的发展,高精度、高重频的卫星测距数据为卫星自转速率的研究奠定了基础。基于中国科学院云南天文台k Hz卫星激光测距系统的卫星实测数据,分析了AJISAI卫星的自转情况。利用正交最小二乘法对原始观测数据进行了预处理,然后利用频谱分析的方法获得了AJISAI卫星实测数据的频谱图,结合AJISAI卫星角反射器面板的排列规律,分析得出2014年4月AJISAI卫星自转的速率约为0.4382 Hz,利用国内的测距数据得到了地球动力学卫星的自转速率。该方法可以推广到对其他类似激光卫星自转速率进行测定,同时为高精度卫星自转模型的建立提供了基础条件。

Other Abstract

With the development of kilo-Herz (kHz) satellite laser ranging technology, high precision and high frequency data of satellite laser ranging is becoming a foundation for the research of satellite spin. Based on Yunnan Observatories kHz satellite laser ranging system, the AJISAI satellite spin is analyzed. Firstly, the original observation data by the orthogonal least square method are proprocessed, and the data of AJISAI using the method of spectrum analysis are studied. Finally, AJISAI satellite corner reflector panel arrangement is combined, AJISAI satellite spin is analyzed, and the satellite spin mean rate is about 0.4382 Hz. This method can be extended to other laser satellite spin determination. At the same time, this method provides a basic condition for building a high precision satellite spin model.
