While competing with terrestrial broadband service providers for the 12GHz spectrum usage rights of their Starlink consumer terminals, SpaceX made important concessions to Kuiper Systems LLC (an Amazon subsidiary).SpaceX asked the FCC earlier this year to allow Amazon to change the satellite's orbital height, plane and angle, that is, to cancel some orbital overlaps between Starlink and Kuiper satellites and increase the distance between them.
SpaceX's Starlink cluster operates at an altitude of 570 km, with 20 satellites in each cluster, belonging to 36 orbital planes. SpaceX's request for changes requires the FCC to allow the company to halve the height of the constellation from the previous 1300 km. Part of Amazon's Kuiper cluster will operate at an altitude of 590 km.
This ensures that when the Kuiper satellite cluster is fully deployed, the highest altitude of SpaceX satellites will be 580 km, which is one kilometer lower than the 9 km orbit tolerance of Kuiper satellite cluster. SpaceX believes that by making concessions to Amazon, the FCC should conditionally allow the company to deploy Starlink satellites in one of the two proposed orbits. It consists of 348 satellites, and a team of 58 satellites operates six orbital planes respectively, allowing SpaceX to cover Starlink to Alaska.
SpaceX has asked the FCC to allow it to test Starlink in Alaska and bring Starlink coverage through polar orbit. SpaceX will also support key tasks in Satellite Internet access areas for federal users, thus contributing to the national security of the United States.
