ABSTRACT:
A vehicle position information transmitter via satellite, a method thereof, a vehicle position tracking system using the same and a method thereof are provided. The transmitter transmits vehicle position information and vehicle ID to the vehicle position information management center through the vehicle position information relay satellite if a satellite network communication state is good as the result of comparing a satellite signal intensity with a mobile communication signal intensity, or transmits vehicle position information and vehicle ID to the vehicle position information management center through the terrestrial network if a terrestrial network communication state is good as the result of comparing a satellite signal intensity with a mobile communication signal intensity.
