FCC Approves Amazon's Satellite Broadband Plan Over SpaceX's Objections

An anonymous reader quotes a report from Ars Technica: Amazon's Kuiper division can start launching satellites to offer broadband service in the US, the Federal Communications Commission said yesterday. The FCC's International Bureau approved Kuiper's orbital debris mitigation plan. This approval was needed to satisfy a condition imposed in 2020 when the Amazon subsidiary received tentative approval for a network of 3,236 satellites in low-Earth orbit. "Our action will allow Kuiper to begin deployment of its constellation in order to bring high-speed broadband connectivity to customers around the world," yesterday's FCC order said. Amazon's biggest competitor for low-latency satellite broadband will be SpaceX's Starlink service, but Amazon's launch schedule puts it a few years behind SpaceX. The companies have fought each other in FCC proceedings, with Amazon objecting to SpaceX's satellite plans and SpaceX filing objections to Amazon's. In approving Amazon's plan yesterday, the FCC dismissed objections from other satellite providers such as SpaceX and Viasat. As the FCC order notes, SpaceX argued that the commission "should limit Kuiper to deploy only 578 satellites in its 630 kilometer orbital shell, and defer action regarding the remainder of the constellation," in order to "address Kuiper's ability to coexist with other systems in and around its 590 kilometer and 610 kilometer shells, and allow for 'continued monitoring' of deployment." A Space filing last month said, "Granting an initial 578 satellites of Amazon's 3,236-satellite system would offer Amazon a path to begin deploying for 'many months,' while providing the Commission with time and additional data to assess the serious issues raised in this proceeding." [...] According to the FCC, SpaceX also argued "that Kuiper's satellite disposal strategy will place the Kuiper satellites in an elliptical orbit that, because of the variable effects of atmospheric drag on orbit evolution, will result in large uncertainties in the predicted trajectories of the Kuiper satellites, making it difficult for other operators to assess and mitigate risk." SpaceX contended that "the large covariances involved in the elliptical orbits may therefore pose a risk to SpaceX's satellites operating at the same altitudes during their orbit raising phase of operations." However, Kuiper responded that it "will perform orbit determination using Global Positioning System (GPS) measurements on all Kuiper satellites during the deorbiting process and share high-accuracy location information with operators on a real-time basis." The FCC accepted that plan and imposed it as a condition on the license. SpaceX and Viasat both "raised concerns that Kuiper's satellite designs are not sufficiently finalized to enable review," but Amazon said the design is complete and that it doesn't expect material changes, the FCC order said. Kuiper would have to apply for a license modification if it does make significant changes.
