SYSTEM AND METHOD FOR DETERMINING A RECEIVER GROUND POSITION

A positioning, navigation and timing solutions for a ground-based device is determined by receiving a satellite RF signal at the ground-based device. It is determined whether the RF signal is from a satellite of interest. A satellite of interest has known data, enabling an estimation of a current lo...

Zusammenfassung:	A positioning, navigation and timing solutions for a ground-based device is determined by receiving a satellite RF signal at the ground-based device. It is determined whether the RF signal is from a satellite of interest. A satellite of interest has known data, enabling an estimation of a current location of the satellite. The RF signal frequency of the satellite of interest is used to collect observed Doppler measurements and time of receipt of the RF signal. The position, navigation and timing solution is determined as a function of the observed Doppler measurements, known data regarding the characteristics of the satellite, and predicted Doppler measurements to enable an estimation of the current location of the receiver.
