Reverse-ephemeris lunar navigation system for long-distance route determination

The disclosed system and method transmit a signal from the surface (or surroundings) of a celestial object to a satellite (for which you know the orbital elements) that re-transmits the signal back to a transceiver on the surface of the celestial object from which a time delay to obtain a range meas...

Beschreibung
Zusammenfassung:	The disclosed system and method transmit a signal from the surface (or surroundings) of a celestial object to a satellite (for which you know the orbital elements) that re-transmits the signal back to a transceiver on the surface of the celestial object from which a time delay to obtain a range measurement and a Doppler shift to obtain the range-rate can be measured. With knowledge of the satellite's orbital elements and the range and range-rate, a location of the transceiver can be determined.
