1. A system for estimating the location of beacons based on spatial relationships and beacon reference data associated with other beacons, said system comprising:

  • a memory area for storing sets of beacon identifiers, said memory area further storing beacon reference data for the beacon identifiers in at least a first one of the sets; and

    a processor programmed to;

    identify a second one of the sets lacking beacon reference data for at least one of the beacon identifiers in said second one of the sets;

    determine one or more beacon identifiers common to the first one of the sets and to the second one of the sets;

    select, from the determined beacon identifiers, beacon identifiers corresponding to beacons that are spatially diverse; and

    calculate the beacon reference data for said at least one of the beacon identifiers based on the beacon reference data associated with the selected beacon identifiers and stored in the memory area.
