Abstract
A system and method for determining the position of people and/or objects, whether mobile or stationary, is presented herein. The system uses fixed and/or portable FM transmitters to transmit synchronized signals. These signals are acquired by a Receiver device which uses the signal timing to perform Time Difference of Arrival calculations to determine the Receiver's location. Then, using some arbitrary communications method, such as wireless communications, the Receiver device can forward its location to some arbitrary type of application system.
