The invention provides a high-speed aircraft positioning method with a satellite constellation; the method comprises the steps: (1) positioning by adopting an inclined orbit satellite constellation containing eight satellites or a Sun-synchronous orbit satellite constellation; (2) setting the on-the-star beam angle of eight satellites to be+-60 degrees and utilizing the direction toward the earth's core as the satellite altitude; and (3) setting the satellite orbital altitude of the eight satellites to be the same and to be 400-600km. The inclined orbit satellite constellation containing eight satellites or the Sun-synchronous orbit satellite constellation is capable of achieving the purpose of positioning a high-speed aircraft; the positioning requirement of the high-speed aircraft in an high-dynamic environment can be satisfied by being independent of an GPS navigation system and adopting less satellites; and the method has good economical efficiency.
