Jamming satellite avoidance method and mega-constellation business device
A jamming satellite avoidance method changes an orbital altitude for each of orbital planes with different normal vectors in a mega-constellation satellite group composed of 100 or more satellites, so as to avoid a jamming satellite controlled by a ground device that is different from a device that controls the mega-constellation satellite group. The jamming satellite is an artificial satellite that includes a propulsion device and adopts a nominal orbital altitude and a nominal orbital inclination at which the mega-constellation satellite group flies, and maintains an average orbital altitude and an average orbital inclination while operating the propulsion device irregularly, and is controlled by the ground device that is different from the device that controls the mega-constellation satellite group.
1. A jamming satellite avoidance method, comprising:
changing an orbital altitude for each of orbital planes, each of the orbital planes existing on mutually different planes, in a mega-constellation satellite group composed of 100 or more satellites, so as to avoid a jamming satellite controlled by a ground device that is different from a device that controls the mega-constellation satellite group; and
synchronously controlling the 100 or more satellites to maintain an average orbital altitude and an average orbital inclination for the mega-constellation satellite group relative to a nominal orbital altitude and a nominal orbital inclination at which the mega-constellation satellite group flies while changing the orbital altitude and the orbital inclination for each of the orbital planes over time.
2. A jamming satellite avoidance method, comprising:
changing a frequency of a radio wave to be transmitted or received or performing spread spectrum in a mega-constellation satellite group composed of 100 or more satellites, so as to avoid radio jamming by a jamming satellite controlled by a ground device that is different from a device that controls the mega-constellation satellite group; and
synchronously controlling the 100 or more satellites to maintain an average orbital altitude and an average orbital inclination for the mega-constellation satellite group relative to a nominal orbital altitude and a nominal orbital inclination at which the mega-constellation satellite group flies while changing the orbital altitude and the orbital inclination for each of the orbital planes over time.
