ABSTRACT:
Disclosed is a device and method for dynamically adjusting orientation of a satellite antenna carried in a movable carrier, including a satellite tracking system and an adjusting device. The satellite tracking system includes a position processor that receives a group of positioning signals comprising a current coordinate from a group of GPS satellites and retrieve a program signal comprised a preset coordinate among at least one of program satellites, a comparator comparing the current coordinate with a preset coordinate to generate an deviation, and a microprocessor processing the deviation to issue a control signal that is fed to the adjusting device for changing orientation of the antenna to match with that of the program satellite.
