Patent ID: 7656311

Claim:
A position tracking system for determining a position of a vehicle within an environment, comprising: a plurality of position-enabled mesh nodes positioned within the environment; at least two vehicle-mounted, position-enabled mesh nodes mounted to respective first and second locations on the vehicle, at least one of the first and second locations corresponding to an extremity of the vehicle, said at least two vehicle-mounted, position-enabled mesh nodes exchanging radio signals with said plurality of position-enabled mesh nodes positioned within the environment to form a mesh network, said at least two vehicle-mounted, position-enabled mesh nodes and said plurality of position-enabled mesh nodes positioned within the environment also exchanging radio signals to determine their relative positions with respect to one another based only on the radio signals exchanged between the position-enabled mesh nodes forming the mesh network, said position tracking system determining the relative position of the vehicle, including the extremity of the vehicle, with respect to said plurality of position-enabled mesh nodes positioned within the environment; and a display system operatively associated with said mesh network, said display system displaying the position of the vehicle relative to said plurality of position-enabled mesh nodes positioned within the environment.
