ABSTRACT:
An active GPS tracking system and method includes a user setting interface for receiving a reporting distance, a distance trigger module, a GPS module and a wireless communication module. The distance trigger module calculates a moving distance of the active GPS tracking system, and generates and sends an interrupt signals to the GPS module to make it enter a working mode when the moving distance is greater than or equal to the reporting distance. Then, the GPS module determines a current position of the active GPS tracking system and determines whether an actual displacement is greater than or equal to the reporting distance to determine if reporting the current position. If the actual displacement is greater than or equal to the reporting distance, the wireless communication module receives the current position from the GPS module, and reports to a monitor center.
