| 1. A method of modifying a location calculation for a group of transmitters, the method comprising:
determining relative locations for the group of transmitters by obtaining a relative location of each of the transmitters
with respect to at least one other transmitter in the group of transmitters;
determining initial geolocations for the group of transmitters, the initial geolocations determined by an external receiver
that is not part of the group;
calculating distances between the transmitters from the initial geolocations;
comparing the calculated distances to the relative locations to compute at least one calibration factor for the group, the
at least one calibration factor being used to adjust subsequent geolocations of the group to substantially include the relative
locations of the transmitters; and
calculating calibrated geolocations for the group of transmitters from the subsequent geolocations that are modified by the
at least one calibration factor.
