| Abstract: | The characteristics,function,structure and principle of the BeiDou Dual-Satellite Navigation System are described,and the limitation of the BeiDou's active location in application is discussed.Considering that the active location mode of the BeiDou cannot keep radio silence and there are needs for radio-silent satellite location,a new approach of passive location technique with the three BeiDou geostationary satellites is presented,including principle,implementation,location accuracy analysis and the present obtainable result of location accuracy.In the end,the merits and application posture about the passive location technique with the three BeiDou geostationary satellites are elaborated. |
