Claim Text:
1. A device comprising: a GNSS receiver configured to receive a GNSS signal having a signal strength; and a control unit coupled to the GNSS receiver, the control unit comprising a network transceiver and a database, wherein the control unit is configure to detect a change of the signal strength and determine a position of the device in response to the detected change of the signal strength, wherein if the signal strength is less than a threshold value, the position of the device is determined based on a network address and data included in the database, and wherein the GNSS receiver is configured to enter a low-power mode following each tracking phase, exit the low-power mode in response to instructions from the control unit to calculate the position of the GNSS receiver and to reenter the low-power mode after the position of the GNSS receiver is calculated.
