Abstract
A system for locating an object within a monitored environment includes a tag transmitter that transmits an RF signal to receivers having unsynchronized clocks. A processor is operative with each receiver and determines clock timing relationships for the clocks based on one of at least propagation or processing delays in the receivers to synchronize receiver performance.
