| 中文摘要 | 为提高针对影响同步通信卫星正常工作的地面干扰源定位精度,回避无邻近卫星无法定位问题,提出低轨卫星辅助的新方法。该方法充分利用低轨飞行所带来的长基线、近距离的好处,并以多普勒差为观测变量,卫星轨道参数为待估参数,可进一步改善定位精度。针对建立的定位数学模型进行计算,其结果显示,当低轨卫星的高度在5000km时,全区域定位精度优于1km。; In order to improve the positioning precision of interference source which affects the normal operation of the synchronous communication satellites and avoid positioning difficulty without neighboring satellite, a new method called LEOAP(LEO satellite aided positioning) is brought forward. The method takes full advantages of longer base line and nearer distance of LEO, with the Doppler difference measurements as observational variables and the orbital parameters of satellite as the parameters to be estimated. Based on the mathematic model of the LEOAP presented, computation is performed, whose results show that interference source positioning precision can reach 1 km by the aid of LEO satellite at the altitude of 5000 km. |
