摘要： A position tracking system for determining a position of a vehicle. The position tracking system invention includes at least two position-enabled mesh nodes mounted to the vehicle and a mesh network operatively associated with the at least two position-enabled mesh nodes mounted to the vehicle. The mesh network is configured to determine a position of the vehicle based on signals received from the at least two position-enabled mesh nodes mounted to the vehicle. The position tracking system also includes a display system, which is operatively associated with the mesh network and which displays the position of the vehicle.

摘要： Methods and apparatus for locating and tracking objects in a mining environment are disclosed that include selecting an operational area within which the locations of a plurality of objects are to be determined and tracked over time. Radio transceiver systems and associated display systems provided to the plurality objects are operated to form an ad-hoc, peer-to-peer network. The relative positions of the various objects are determined by measuring the time-of-flight of radio signals exchanged between various ones of the radio transceiver systems and analyzing the time-of-flight of such exchanged radio signals. The relative positions of at least some of the objects within the operational area are then displayed on the display system.

摘要： A radio-based position location system for determining a relative position of a first object with respect to a second object may include a first radio operatively associated with the first object. A first directional antenna having at least a high gain region is mounted to the second object so that the high gain region is directed generally outwardly from the second object and defines a first detection zone. A second directional antenna having at least a high gain region is also mounted to the second object and is oriented so that the high gain region is also directed generally outwardly and defines a second detection zone. A second radio connected to the first and second directional antennas exchanges radio signals with at least the first radio to determine the relative position of the first object with respect to the second object at least in part by determining a time-of-flight of a radio signal. The radio signals are primarily exchanged via the first directional antenna when the first object is in the first detection zone, whereas the radio signals are primarily exchanged via the second directional antenna when the first object is in the second detection zone.
