Claim 18:
19. A satellite visibility assignment method, comprising:
setting, based on visibility information, visibility units each including a combination of a satellite and a station to communicate with the satellite, a lower limit of a visibility start time, and an upper limit of a visibility end time;
setting one or more combinations of the set visibility units;
determining whether the visibility start time and the visibility end time are settable for each of the set one or more combinations of the visibility units within a range satisfying at least one constraint of a visibility time, a visibility interval, the lower limit of the visibility start time, or the upper limit of the visibility end time, and calculating the visibility start time and the visibility end time through an optimization calculation when the visibility start time and the visibility end time are settable; and
selecting, from the set one or more combinations of the visibility units, a combination of the visibility units to be used based on determination as to whether the visibility start time and the visibility end time are settable and based on an evaluation index value acquired based on the visibility start time and the visibility end time set when the visibility start time and the visibility end time are determined to be settable.
