1. A satellite signal control box, coupled with at least one antenna unit mounted on a vehicle through a driving system to drive the antenna unit to point at at least one of a plurality of satellites in the space, comprising:

  • a driving control circuit coupled with the driving unit and receiving a scan driving signal to trigger the antenna unit to scan in the space so as to generate a scan data;

    a processing unit, coupled with the driving control circuit for analyzing the scan data so as to obtain individual satellite coordinates of the satellites; and

    a memory unit coupled with the processing unit for storing the satellite coordinates of the satellites;

    wherein, upon receiving a lock-on signal, the processing unit captures the respective satellite coordinate of one of the satellites to be locked (target satellite) according to the lock-on signal;

    wherein the processing unit thereafter sends an antenna control signal to the driving control circuit according to the satellite coordinate being captured and then the driving control circuit triggers a driving signal to reach the driving system so as to point the antenna unit at the target satellite.
