||In maritime mobile satellite communications,
receiving satellite signal level
varies due to direction and motion of a ship.
Then the communications are sometimes interrupted,
because the receiving satellite signal level decreases
when the antenna is shadowed by the ship's body.
Thus it is important to evaluate how qualities of satellite
communications vary during ship operations.
To evaluate temporal variances of receiving satellite
signal level of the ship in motion, modeling and numerical
simulation were performed with considering the effect
that the antenna was shadowed by the ship's body.
In addition, effects of pitching, rolling and yawing
were taken into accounting the calculations.
