1. A tracking device, comprising:

  • a positioning module for satellite navigation;

    a long-range transceiver for digital cellular communication; and

    a microcontroller, controlling the positioning module and the long-range transceiver,wherein;

    the microcontroller is further configured to operate the long-range transceiver to regularly transmit position information of the tracking device to a server during a data-collection period for behavior analysis of a tracked object equipped with the tracking device and for safe-zone demarcation of the tracking device, the safe-zone demarcation is adaptive to habitual behaviors of the tracked object, and the habitual behaviors are obtained from the behavior analysis;

    the position information indicates appearance positions of the tracking device that show positions at which the tracking device appears;

    the data-collection period lasts N days, N is a number and each day of the N days is divided into time slots;

    a correlation analysis is performed on the appearance positions of the tracking device in the same time slot between the N days, to estimate confidence levels of the appearance positions for each time slot of a day; and

    each time slot of a day corresponds to a position-confidence threshold for the safe-zone demarcation.
