New many system based on broadcasting and communication will be able to take a more useful and fast informations around out lifestyle. But ship, airplane and car never use the application of the cable communication system and also have a weak point of receiving qualitics using convennntional V/UHF TV broadcasting.
One of typically case of mobile systems, a ship has been isolated long time during the navigation. However, For the last couple of years, the DBS have been proposed very useful systrm to access the broading service in more widely sea. But the antenna tracking system for maritime DBS receving is required complicated control system because of the those complex motion represented pitching, yowing and rolling etc.
In our research, we have developed the antenna tracking system for receving in mobile.
