摘要: 针对利用LEO星载GPS接收机对GPS卫星进行掩星观测的任务,在建立LEO卫星轨道模拟系统的基础上,考虑卫星几何关系和天线视场的情况下,对掩星事件进行了模拟。分析了对于单颗LEO卫星,掩星事件的分布和数量随着LEO轨道参数包括轨道升交角距、升交点赤经、轨道高度和倾角而变化的规律,并得出了相应结论

Abstract: Focused on the task of carrying out GPS occultation observations with a receiver set on LEO satellite, this paper developes the LEO orbit simulation system based on which the occultation events can be simulated taking into account the geometric relationship of the satellites and the field of view of the receiver antenna. In this paper, the impacts of 4 types of LEO orbit parameters—argument of latitude(AOL), right ascension of ascending node(RAAN), orbit height and inclination—on the distribution and number of occultation events a single LEO satellite observed are discussed through simulation and some conclusions are drawn.
