Satellite constellation forming system, satellite constellation forming method, ground facility, and business device

A satellite constellation forming method of a satellite constellation forming system to form a satellite constellation which is composed of a satellite group and in which the satellite group cooperatively provides a communication service, the satellite constellation having a plurality of orbital planes in each of which a plurality of satellites fly at a same orbital altitude,

• wherein each satellite of the satellite group includes an inter-satellite communication device and a satellite-ground communication device,
• the satellite constellation forming method comprising
• forming the satellite constellation which has ten or more orbital planes with different normal directions, and in which at least one relative angle in an azimuth direction of adjacent orbital planes of the plurality of orbital planes is arranged to be uneven and satellite-ground communication devices of satellites flying in orbital planes spaced unevenly have a communication range that achieves complete ground coverage above the equator, and forming a passage region R for a space object to pass through in the satellite constellation.

A ground facility included in a satellite constellation forming system to form a satellite constellation which is composed of a satellite group and in which the satellite group cooperatively provides a communication service, the satellite constellation having a plurality of orbital planes in each of which a plurality of satellites fly at a same orbital altitude,

• wherein each satellite of the satellite group includes an inter-satellite communication device and a satellite-ground communication device,
• the ground facility comprising
• processing circuitry to form the satellite constellation which has ten or more orbital planes with different normal directions, and in which at least one relative angle in an azimuth direction of adjacent orbital planes of the plurality of orbital planes is arranged to be uneven and satellite-ground communication devices of satellites flying in orbital planes spaced unevenly have a communication range that achieves complete ground coverage above the equator, and form a passage region R for a space object to pass through in the satellite constellation.
