1. A method for establishing a reference grid and locating an object within the reference grid, the method comprising:

  • receiving, by at least one anchor node of a plurality of anchor nodes in a network, an indication that a selected anchor node is to function as a master anchor node;

    transmitting, by the master anchor node, a ranging message as an ultra-wideband (UWB) signal;

    receiving, by the master anchor node, a ranging message response from each of the plurality of anchor nodes in the network;

    generating, by the master anchor node, a reference grid representing physical locations of the plurality of anchor nodes within the network based upon the received ranging message responses; and

    distributing, by the master anchor node, the reference grid to each of the plurality of anchor nodes.
