Paper Abstract

In order to resolve the problem of high precision in positioning ground interference sources by which someone attack geostationary satellites, we brought forward a new method called LEOAP (LEO Satellite Aided Positioning). Taking advantage of the longer base line and nearer distance which is brought through using low orbit satellite, we built a positioning model of LEOAP based on the measurement of differential Doppler parameters, with orbital parameters of satellite as parameters to be estimated. Results of simulation show that the precision of positioning aided by low orbit satellites at the height of 5000 km can reach 1 km, thus proving the correctness of LEOAP.
