System and method for enabling a wireless computing device to continuously determine its position includes a wireless computing device and a wireless positioning system substantially collocated therewith. The wireless positioning system has a first positioning mode in which it communicates with a wireless positioning network to enable the geographic location of the computing device to be determined upon reception of signals from the positioning network and a second positioning mode in which it enables the geographic location of the wireless computing device to be determined upon reception of signals from one or more of the wireless beacons and analysis of the signals in light of positional information about wireless beacons contained in a database. The wireless positioning system switches between the positioning modes depending on reception of signals from the wireless positioning network.
