Abstract
Methods and systems for providing an improved geolocation of a plurality of transmitters are disclosed. In one embodiment, a method for providing a geolocation of a plurality of transmitters includes determining a relative location of each transmitter in the plurality of transmitters with respect to at least one other transmitter in the plurality of transmitters; determining an initial geolocation of the plurality of transmitters; computing a calibration factor by comparing the initial geolocation of the plurality of transmitters to the relative locations of the plurality of transmitters; and determining a calibrated geolocation of the plurality transmitters by adjusting at least one final geolocation of the plurality of transmitters by the calibration factor.

A method for providing a geolocation of a plurality of transmitters, comprising:
- determining a relative location of each transmitter in the plurality of transmitters with respect to at least one other transmitter in the plurality of transmitters;
- determining an initial geolocation of the plurality of transmitters;
- computing a calibration factor by comparing the initial geolocation of the plurality of transmitters to the relative locations of the plurality of transmitters;
- and
- determining a calibrated geolocation of the plurality of transmitters by adjusting at least one final geolocation of the plurality of transmitters by the calibration factor.
A system for providing a calibrated geolocation of a plurality of transmitters, comprising:
- a plurality of transmitters, the plurality of transmitters configured for multidirectional signal communication, the plurality of transmitters operable to create a known relative location for each transmitter with respect to another transmitter;
- at least one receiver in multidirectional signal communication with the plurality of transmitters, the at least one receiver configured to determine a geolocation for each of the plurality of transmitters;
- a calibration module for generating a calibration factor determined by comparing the known relative locations to the geolocation of the plurality of transmitters;
- and
- an output module for determining the calibrated geolocation by adjusting a final geolocation of the plurality of transmitters by the calibration factor.
A system for providing a geolocation of a transmitter platform, comprising:
- a platform configured with two or more spatially diverse transmitters, each transmitter configured to receive a signal and send a signal;
- at least one receiver in communication with the two or more spatially diverse transmitters, each receiver configured to send a signal and receive a signal to determine geolocations of the two or more spatially diverse transmitters;
- a computer for calculating a calibration factor determined by comparing a known relative location and the geolocations of the two or more spatially diverse transmitters;
- and
- an output calibrated geolocation display determined by adjusting a final geolocation of the plurality of transmitters by the calibration factor.
