Abstract
The described geolocation techniques determine a location of an earth-based vehicle using a non-geostationary satellite. For instance, the non-geostationary satellite receives signals transmitted by the earth-based vehicle, determines the arrival times of the signals, and the position information of the satellite corresponding to the arrival times of the signals. The arrival times and position information of the satellite are sent to a signal processing unit to determine a location of the vehicle.
Claims24
A system for performing geolocation, comprising:
- a data collection apparatus in a non-geostationary satellite, the data collection apparatus includes a processor to implement a method comprising:
- receiving a number of signals from an earth-based vehicle;
- determining arrival times of the number of signals;
- obtaining position information of the non-geostationary satellite corresponding to the arrival times of the number of signals;
- and
- sending, to a signal processing unit, the arrival times and the position information of the non-geostationary satellite for the number of signals;
- the signal processing unit configured to determine a location of the earth-based vehicle, the signal processing unit includes a processor to implement a method comprising:
- receiving the arrival times and the position information of the non-geostationary satellite for the number of signals;
- selecting a plurality of candidate locations to determine the location of the earth-based vehicle;
- and
- processing the arrival times, the position information, and the plurality of candidate locations to determine the location of the earth-based vehicle.
A signal processing unit to determine a location of an earth-based vehicle, the signal processing unit includes a processor to implement a method comprising:
- receiving arrival times and position information of a non-geostationary satellite associated with a number of signals received by the non-geostationary satellite from the earth-based vehicle;
- selecting a plurality of candidate locations to determine the location of the earth-based vehicle;
- and
- processing the arrival times, the position information, and the plurality of candidate locations to determine the location of the earth-based vehicle.
