Abstract
A system and method for locating an object is provided. A locating circuit substantially secured to the object. A plurality of monitoring units are positioned remotely from the locating circuit, each positioned in a different location, wherein at least a portion of the plurality of monitoring units are positioned in an outdoor environment. An omnidirectional signal is intermittently communicated between the locating circuit and the plurality of monitoring units. A calculator is in communication with each of the plurality of monitoring units. The calculator determines a duration of transmission time of the omnidirectional signal for each of the plurality of monitoring units, and the locating circuit. The calculator calculates a location of the locating circuit using the determined duration of transmission time for each of the plurality of monitoring units and the locating circuit.
