Abstract: A method for establishing a location anchor network includes receiving, by a location application executing on a processor, GPS positions from each of the plurality of location anchors, determining, by the location application, a preliminary network topology using the GPS positions for each of the plurality of location anchors, receiving, by the location application, an inter-location anchor spacing between the plurality of location anchors, determining, by the location application, a final network topology based on the GPS position and the inter-anchor spacing, and storing the final network topology in a memory. The plurality of location anchors are portable, and the plurality of location anchors are deployed at a location associated with a structure. The final network topology defines a position estimate for each location anchor of the plurality of location anchors.
