1. A method for controlling a satellite communication of a satellite flying on a trajectory over the earth, the method comprising
providing a first target location on the surface of the earth;
determining the trajectory of the satellite over the earth;
identifying a first interference restrictive area, which the satellite trajectory passes;
determining an elevation angle in respect to the satellite and the first target location, wherein the elevation angle is an angle between a horizontal plane of the earth and a vector pointing from the first target location to the satellite along the trajectory at given moment of time; and
activating a first communication beam from the satellite towards the first target location when the elevation angle is between an activation angle and a deactivation angle, wherein
the activation angle is less than the deactivation angle if the first interference restrictive area is located in a forward direction in respect to the satellite motion along the trajectory, and
the deactivation angle is less than activation angle if the first interference restrictive area is located in backward direction in respect to the satellite motion along the trajectory and;
deactivating the first communication beam when the elevation angle is beyond the deactivation angle.
