ANTENNA SYSTEM FOR SATELLITE LOCK-ON AND METHOD FOR OPERATING THE SAME
First Claim
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.

Abstract
An antenna system and a corresponding method for satellite lock-on applied to vehicles automatically lock on at least one satellite in the space by means of a lock-on signal. The technique features on a scan driving signal that initiates a space scan of the antenna system so as to obtain a scan data. According to peak values of the scan data, coordinates of a plurality of satellites in the space are realized and individually recorded. Then, after receiving a lock-on signal, the satellite coordinate of the satellite to be locked is retrieved so as to drive the antenna to point at the satellite to be locked.
