讨论X射线脉冲星导航技术应用于“夸父A”卫星的可行性。在“夸父A”卫星上搭载X射线探测器接收3颗脉冲星的脉冲信号,通过测量信号到达卫星和太阳系质心的时间偏差和频率漂移6个观测量,可以确定卫星的3维位置和3维速度。根据卫星状态与目标轨道的偏差采用小推力方法可以对卫星进行轨道控制。本文对此进行了数值模拟,并给出了相应的分析。结果表明利用X射线脉冲星导航,在现有的技术下就可以将“夸父A”卫星控制在日地系第一平动点halo轨道的附近。
Discuss the feasibility of applying X-ray pulsar navigation technology to the “Kuafu A” satellite. In the “Kuafu A” satellite equipped with X-ray detector to receive three pulsar pulse signal, by measuring the signal to reach the center of gravity of the satellite and solar system time drift and frequency drift of 6 observations, you can determine the satellite’s 3-dimensional position And 3-dimensional speed. According to the deviation of the satellite state and the target orbit, the small thrust method can be used to control the orbit of the satellite. This article has carried on the numerical simulation, and has given the corresponding analysis. The results show that with the use of X-ray pulsar navigation, the “Kuafu A” satellite can be controlled near the halo track of the first translational point on the Japanese-Japanese system under the existing technology.
