Abstract
For the improvement of lifesaving rate and reduction of sequelae on serious illness patients who are transported by ambulance, we propose a new mobile communication system, i.e. motion pictures transmission from mobile ambulance via satellite to the emergency medical center for the adequate diagnosis by the medical doctors. For this purpose, satellite antenna tracking system onboard the experimental car has been developed. This paper describes the overall system of the mobile ambulance data transmission via highly inclined satellite for the avoidance of shadowing and then some details of the antenna tracking system.
