Patent ID: 8059029

Claim:
An active GPS tracking system used to report a position of a target to a monitor center, comprising: a user setting interface, used to receive a reporting distance; a distance trigger module, used to calculate a moving distance of the active GPS tracking system and generate and send an interrupt signal when the moving distance is greater than or equal to the reporting distance; a GPS module that enters a working mode if receiving the interrupt signal, and used to determine a current position of the active GPS tracking system, and determine whether an actual displacement is greater than or equal to the reporting distance to determine if the current position is required to be reported; and a wireless communication module, used to receive the current position from the GPS module, wherein if the actual displacement is greater than or equal to the reporting distance, the wireless communication module reports the current position to the monitor center; and a processor to execute the user setting interface, the distance trigger module, the GPS module and the wireless communication module; wherein the GPS module enters a sleep mode if sending the current position.
