太阳同步轨道卫星交点地方时漂移估算方法研究

A Method to Estimate the Excursion of Sun Synchronous Orbit Satellite Orbital Nodical Local Time

根据我国第一代极轨气象卫星"风云一号"C(FY 1C)星轨道实际观测值,分析了太阳同步轨道卫星轨道漂移的一般规律,提出了一种简便有效的卫星交点地方时漂移估算方法,并用FY 1C星实际的交点地方时漂移量,对该方法进行了分析和改进。

In this paper, the common rule of sun synchronous orbit satellite orbital excursion was obtained by analyzing the actual orbit data of FY1C, the first generation polar orbital meteorologic satellite in China, and a simple but effective method to estimate the excursion of satellite orbital nodical local time was also presented. By contrasting actual excursion of FY1C, the method was analyzied and amended. 
