Claim 7:
8. A ground device of a satellite constellation forming system that forms a satellite constellation which is composed of a satellite group and in which the satellite group cooperatively provides a service, the satellite constellation having a plurality of orbital planes in each of which a plurality of satellites fly at a same orbital altitude, the ground device comprising:
a communication device to transmit and receive signals to track and control each satellite of the satellite group constituting the satellite constellation; and
processing circuitry to generate an orbit control command that controls each of the satellites of the satellite group and forms the satellite constellation in which orbital altitudes of the plurality of orbital planes are mutually different, and relative altitude differences between orbital planes in the plurality of orbital planes are sequentially arranged to be sinusoidal,
wherein the processing circuitry generates the orbit control command to sequentially change an orbital altitude of each orbital plane of the plurality of orbital planes while maintaining a sinusoidal arrangement of the relative altitude differences between adjacent orbital planes in the plurality of orbital planes, and
wherein the communication device transmits the orbit control command to each satellite.
