Abstract

A method of optimizing driving of an antenna for communication of an artificial satellite, by controlling a rotation angle of the antenna, according to an embodiment of the disclosure, includes: receiving a basic profile indicating a change in a rotation angle of the antenna such that a center line of the antenna points to a ground station in response to movement of the artificial satellite; determining a processing section with reference to points at which a rotation velocity of the antenna, for the basic profile, is zero; and generating an optimization profile that determines the change in the rotation angle of the antenna by configuring the rotation velocity of the antenna, for the processing section, with a preset optimized rotation velocity.

A method of optimizing driving of an antenna for communication of an artificial satellite by controlling a rotation angle of the antenna, the method comprising:

receiving a basic profile indicating a change in a rotation angle of the antenna such that a center line of the antenna points to a ground station in response to movement of the artificial satellite;
determining a processing section with reference to points at which a rotation velocity of the antenna, for the basic profile, is zero;
and
generating an optimization profile that determines the change in the rotation angle of the antenna, by configuring the rotation velocity of the antenna, for the processing section, with a preset optimized rotation velocity;
wherein the receiving of the basic profile comprises:
receiving information regarding the optimized rotation velocity of the antenna, determined according to a structure of the artificial satellite;
receiving information regarding a rotation angle determined according to a structure of the antenna and at which communication between the antenna and the ground station is allowed;
and
generating an uppermost profile and a lowermost profile, based on the rotation angle at which the communication between the antenna and the ground station is allowed and the basic profile.
