Abstract(in English) In maritime mobile satellite communications, mechanical controllable satellite following bases are used to compensate changes of antenna orientation due to fluctuations of a ship attitude caused by waves or winds of the sea Orientations of antennas are limited so that transmitted electromagnetic waves from the antennas are not affected by structures on ships Thus it is allowed to transmit wave when a clearance angle is greater than a certain criteria Our research group have researched about fundamental relation between clearance angles and interferences for other satellites or other systems on the ship by numerical simulations for a simplified model In this report, a more realistic ship model are used for the simulations As a result, a clearance angle, which interferences to the receiving satellite are small, has been found out under the conditions of the simulations in this report
