Abstract:
1. A method of providing an enhanced location based service via a mobile device, including: determining, by a processor of the mobile device, an initial position; generating, by the processor, at least one set of local position information based on locally determined location information; receiving, by an antenna of the mobile device, location information from one or more external location tracking systems; generating, by the processor, at least one set of external position information based on the location information received from the one or more external location tracking systems; receiving, by the antenna, distance information from multiple mobile devices in a communication group; generating, by the processor, at least one set of proximity position information based on the distance information received from the multiple mobile devices in the communication group; generating, by the processor a final location estimation set comprising a position, a velocity, and an acceleration, based on the at least one set of local position information, the at least one set of external position information, the at least one set of proximity position information and the initial position; and using, by the processor, the final location estimation set to provide a location based service.
