Abstract

本文首先对鹊桥卫星任务轨道进行计算,通过数值方法给出一条有效的近似模拟鹊桥卫星探测任务的目标轨道。计算给出了云南天文台距鹊桥卫星的最大和最小距离,并对最大距离和最小距离激光测距回波光子数进行对比分析,对影响鹊桥卫星激光测距成功率的关键因素进行研究对比分析。计算在最近观测距离时间段鹊桥卫星与月球的最小距离和最小z方向垂直距离,针对鹊桥卫星分析计算给出2019年下半年云南天文台鹊桥卫星激光测距观测任务时刻表,根据以往月球激光测距积累的经验,通过对观测任务时刻表的分析计算结合影响测距的因素给出了提高激光回波光子数和测距成功率的改善方法。

Other Abstract

In this paper, we first calculate the queqiao satellite mission orbit, and give a valid approximate orbit to simulated queqiao satellite detection task by numerical integration method. By calculating the maximum and minimum distances between the queqiao satellite and Yunnan Observatory, the maximum distance and the minimum distance queqiao satellite laser ranging echo photon number are compared and analyzed respectively, which affects the queqiao satellite laser ranging. The key factors of the success rate of queqiao satellite laser ranging are studied and compared. Calculate the minimum distance between the queqiao satellite and the moon and the minimum z-direction vertical viewing distance during the most recent observation distance period. According to the analysis and calculation of the queqiao satellite, the schedule of the task observation of the queqiao satellite laser ranging observation of the Yunnan Observatory in the second half of 2019 is given. According to the experience of lunar laser ranging accumulation in the past, the improvement method of laser echo photon number and ranging success rate is given by the calculation and analysis, the observation task schedule combined with the factors affecting the ranging.
