A non-transitory computer-readable medium embodying a set of computer-executable instructions, which, when executed in connection with a computerized system comprising a central processing unit, a localization signal receiver, a display and a memory, cause the computerized system to perform a method comprising:

• a. receiving at least one localization signal using the localization signal receiver;
• b. measuring a strength of the received localization signal;
• c. determining whether the computerized system is co-located with an anchor device;
• and
• d. if the computerized system is determined to be co-located with the anchor device, determining a location based at least on the measured strength of the received localization signal.
