1. A satellite constellation forming method comprises a satellite deployment step S, a spacecraft acceleration step S, a spacecraft orbiting step Sand spacecraft deceleration step, and the aforementioned steps are repeated in order. In the satellite deployment step S, deploying one of the satellites into the circular orbitfrom the spacecrafton the circular orbit. In the spacecraft acceleration step S, accelerating the spacecraftand switching the orbit from the circular orbitto a spacecraft transfer orbitin the same orbit plane. In the spacecraft orbiting step S, making the spacecraftorbit along the spacecraft transfer orbita plurality of times. In the spacecraft deceleration step, decelerating the spacecraftand switching the orbit from the spacecraft transfer orbitto the circular orbitin the same orbit plane.

Satellite constellation forming method and forming device

A spacecraftincludes wingsor an airframewhich generates lift in an atmosphere, a thrusterwhich accelerates or decelerates rotating speed in an orbit, an attitude controllerwhich controls an attitude of the airframe, and an orbital plane controllerwhich controls the orbital plane change. The orbital plane controller causes the spacecraftto enter the earth's atmospherewithin a pre-change orbital plane Fb (A&#x2192;B&#x2192;C), changes the orbital plane by using the lift of the wingsor airframein the earth's atmosphere(C&#x2192;D&#x2192;E), and then lifts the spacecraftup to the post-change orbital altitude (E&#x2192;F).
