LEO-LEO掩星事件持续时间及卫星间相对角速度仿真分析
Simulation of Duration of LEO-LEO Occultation Events and Relative Angular Velocity between Satellites
摘要
Abstract
The effects of satellite orbit parameters on the duration of LEO-LEO occultation events and relatively angular velocity between satellites are discussed through simulation.The results show that the orbit parameters of LEO-LEO satellites,which have great effects on the duration of LEOLEO occultation events,are the orbit inclination,followed by right ascension of ascending node and the orbit height.However,the argument of perigee has little effect on the duration.As the inclination angles of LEO-LEO satellites are complementary angles,the duration reaches its minimum value 98s.If the sum of the orbit inclination and the difference of Right Ascension of Ascending Node (RAAN)of two satellites is from 120° to 240°,the duration is about from 100 s to 150 s.The higher the satellite orbit is,the shorter the duration of the occultation is.During the occultation events,the maximum of relative angular velocity in the horizontal direction is about 0.14(°).s-1,and the maximum of relative angular velocity in the vertical direction is about 0.078(°).s-1.These conclusions provide valuable reference for the design of LEO-LEO occultation orbit,the transmitter,and the receiver.关键词
