Abstract:
1. A device for orienting a satellite antenna carried in a movable carrier by detecting a current coordinate of the movable carrier in accordance with a series of positioning signals received from a group of GPS satellites, the satellite antenna being arranged to orient a selected program satellite to receive a program signal sent from the program satellite, comprising: a satellite tracking system comprising: a GPS position receiver that receives the current coordinate of the movable carrier with respect to the program satellite; a register that stores the preset coordinate of the program satellite; a GPS position comparator that compares the current coordinate of the movable carrier with the preset coordinate of the program satellite to generate a deviation signal; and a microprocessor that receives the deviation signal and correspondingly issues a correction control signal; and an antenna adjusting device adapted to mechanically and operatively couple to the satellite antenna, comprising an adjusting mechanism that receives the correction control signal and operates in accordance with the correction control signal to orient the satellite antenna.
