| 摘 要： | 针对低地球轨道（LEO）卫星对全球卫星定位系统（GPS）卫星的掩星观测任务,在考虑LEO和GPS卫星几何关系及掩星观测天线视场的条件下,建立轨道模拟系统,对全球和区域内的掩星事件进行了模拟。对单颗卫星,用分离变量法讨论了卫星轨道参数对掩星事件数量和时空分辨率的影响,比较了大气层与电离层掩星事件的差别,并根据分析结果用混...

| Abstract: | Focused on the task of carrying out GPS occultation observations with a receiver set on LEO satellite,the orbit simulation system was developped while the geometry relationship between satellites and condition of GPS receiving antenna's inspection was taking into account in this paper,which was applied to simulate the global and regional occultation events.For single satellite,each orbit parameter's effect on amount and space-time resolution of occultation events was analyzed by variable-separate method.The... |
