Abstract
A satellite constellation forming system forms a satellite constellation (20) including two orbital planes each having a different normal direction and in each of which the same number of satellites fly. A satellite constellation forming unit gradually changes an orbital altitude of at least one orbital plane of the two orbital planes from a state in which satellite passage timings of satellites flying in the two orbital planes do not coincide with each other at an intersection neighborhood point (Pc) between the two orbital planes in each of the two orbital planes, while maintaining the state in which the satellite passage timings do not coincide with each other.
Claims15
A satellite constellation forming system to form a satellite constellation including two orbital planes each having a different normal direction and in each of which the same number of satellites fly, the satellite constellation forming system comprising
- processing circuitry to gradually change an orbital altitude of at least one orbital plane of the two orbital planes from a state in which satellite passage timings of satellites flying in the two orbital planes do not coincide with each other at an intersection neighborhood point between the two orbital planes in each of the two orbital planes, while maintaining the state in which the satellite passage timings do not coincide with each other.
A satellite constellation forming method of forming a satellite constellation including two orbital planes each having a different normal direction and in each of which the same number of satellites fly, the satellite constellation forming method comprising
- changing gradually an orbital altitude of at least one orbital plane of the two orbital planes from a state in which satellite passage timings of satellites flying in the two orbital planes do not coincide with each other at an intersection neighborhood point between the two orbital planes in each of the two orbital planes, while maintaining the state in which the satellite passage timings do not coincide with each other.
A satellite constellation comprising two orbital planes each having a different normal direction and in each of which the same number of satellites fly,
- wherein an orbital altitude of at least one orbital plane of the two orbital planes is gradually changed from a state in which satellite passage timings of satellites flying in the two orbital planes do not coincide with each other at an intersection neighborhood point between the two orbital planes in each of the two orbital planes, while maintaining the state in which the satellite passage timings do not coincide with each other.
A ground device of a satellite constellation forming system to form a satellite constellation including two orbital planes each having a different normal direction and in each of which the same number of satellites fly, the ground device comprising:
- a communication device to transmit and receive signals for tracking and controlling each satellite in a satellite group constituting the satellite constellation;
- and
- processing circuitry to generate an orbit control command to gradually change an orbital altitude of at least one orbital plane of the two orbital planes from a state in which satellite passage timings of satellites flying in the two orbital planes do not coincide with each other at an intersection neighborhood point between the two orbital planes in each of the two orbital planes, while maintaining the state in which the satellite passage timings do not coincide with each other,
- wherein the communication device transmits the orbit control command to each satellite.
