摘要：An improved extended ephemeris navigation receiver includes a fully

autonomous satellite navigation receiver for receiving microwave transmissions fromorbiting navigation system satellites, and able to demodulate navigation messages thatinclude the ephemerides for those navigation system satellites. The improvementsinclude a force model of the accelerations acting on a particular satellite vehicle, and areexclusive to the receiver. A single observation of the ephemeris for each SV is input andpropagated days into the future by integrating each SV's orbital position with its

corresponding force model. The fully autonomous satellite navigation receiver thereafterhas available to it extended ephemeris predictions that can be used as substitutes whensaid navigation messages from the respective SV cannot otherwise be immediatelyobtained and demodulated.
