Hybrid constellation and flying object monitoring system

A hybrid constellation comprising:

• a communication constellation including a plurality of artificial satellites flying on a same orbital plane for each of a plurality of orbital planes;
• and
• a mission satellite to be introduced among any artificial satellites on any of the plurality of orbital planes, wherein
• each of the plurality of artificial satellites includes a fore-and-aft communication device for communication as directed ahead in a flying direction and behind in the flying direction and a left-and-right communication device for communication as directed leftward in the flying direction and rightward in the flying direction,
• the mission satellite includes a fore-and-aft communication device and a mission device, and
• the communication constellation
• forms an annular communication network by each of the artificial satellites forming a communication network with an artificial satellite ahead in the flying direction and an artificial satellite behind in the flying direction by using the fore-and-aft communication device, for each orbital plane,
• forms a mesh communication network by each of the artificial satellites forming a communication network with an artificial satellite on an adjacent orbital plane on each of left and right in the flying direction by using the left-and-right communication device, on the plurality of orbital planes,
• after the mission satellite starts flying among the artificial satellites, reconstructs and forms the annular communication network including the mission satellite and also reconstructs and forms the mesh communication network, and
• each of the artificial satellites on each orbital plane crosses each of a northern edge of the orbital plane and a southern edge of the orbital plane in synchronization with artificial satellites on other orbital planes;
• when crossing the northern edge of the orbital plane, forms a communication network with an artificial satellite crossing a northern edge of an adjacent orbital plane, which is an orbital plane adjacent to the orbital plane, by the fore-and-aft communication device;
• and, when crossing the southern edge of the orbital plane, forms a communication network with an artificial satellite crossing a southern edge of the adjacent orbital plane, by the fore-and-aft communication device.
