Abstract
A system and method for determination the relative location of a mobile object is described that includes building a database of known/expected locations with the exact longitude and latitude for each location. Next, an estimated location for a mobile object is generated using information from the cellular network and an area boundary is defined around the mobile object that defines, with some probability, where the object is actually located. The known locations in the database that fall within the area boundary are then identified and a relative probability is calculated for each known location that indicates its relative likelihood of where the mobile object is actually located. From this information at least the most probable location of the mobile object is determined along with a measure of estimation confidence.
