Abstract:
1. A positioning system for a movable object, comprising a positioning terminal adapted to be disposed on the movable object, said positioning terminal including: a satellite-based positioning module adapted to receive satellite-transmitted signals and to generate positioning data from the satellite-transmitted signals; a detecting module adapted to detect status of the movable object, and operable to generate an alarm signal when said detecting module detects an abnormal status of the movable object; a processing module coupled to said satellite-based positioning module and said detecting module, said processing module including a storage medium for storing the positioning data from said satellite-based positioning module, and a processing unit for processing the positioning data stored in said storage medium and for outputting geographical information that contains geographical location of the movable object, said processing unit further outputting alarm information based on the alarm signal received from said detecting module; and a first wireless communication module coupled to said processing module, and operable to wirelessly transmit the geographical information and the alarm information from said processing module; wherein said first wireless communication module is further operable to receive a control signal that is provided to said processing module, said processing module selectively activating said satellite-based positioning module to update the positioning data and selectively enabling and disabling operation of said detecting module according to the control signal received thereby.
