Abstract
Systems and methods for locating an object are disclosed herein. The locator system includes a plurality of reference units and a processor in communication with the reference units. The reference units are positioned about a region in which a mobile unit is located, and each reference unit includes a transceiver for transmitting and receiving a transaction-based location signal to and from the mobile unit. The processor is configured for estimating time offsets between the mobile unit and reference units and aligning the transaction-based location signals from the reference units by removing the time offsets. The processor is further configured for collectively processing data representative of the aligned location signals based on a plurality of potential locations to identify at least one of the potential locations as a likely mobile unit location.
