Dual-satellite geolocation system is an effective passive location technique. This method can locate a stationary emitter on Earth by using time and frequency differences of arrival (TDOA/FDOA).In this paper, the rank of the observation matrix was proposed as standards of location observability, established location models, analysed the observability of aerial moving target location with the representative motion, such as uniform linear model and maneuvering turn model. Finally, simulation results presented a conclusion that Dual-satellite geolocation system could implement location for aerial moving target under some restrictions.
