OneWeb, Telesat, Kepler Continue Fight With SpaceX Over Starlink

filings Tuesday. SpaceX's read of Section 25.261 of the rules doesn't line up with its plain language and reads requirements in it that don't exist, OneWeb said. It said the rules on selection order for home spectrum priority don't require anything of a satellite other than being part of the relevant system, launched and capable of operating in the relevant band. The company said its six satellites all fit that bill and SpaceX is wrongly applying rules on the geographic scope of spectrum sharing to shoehorn in home priority requirements that don't exist. Telesat also said SpaceX was conflating separate provisions of Section 25.261 and that the company's interpretation goes against FCC stated objectives of fostering competition and efficient spectrum use. It said adding the possession of an operating earth station to the first choice determination makes it dependent on arbitrary factors like whose earth station application is opposed and how quickly that earth station application is processed. Kepler echoed those arguments and said it launched and began operating its satellite more than year before any other Ku-band claimant. It said SpaceX's read of the rules "serves no interest other than to skew the home spectrum priority in its favor." SpaceX said OneWeb's recon petition was followed by its "series of shifting arguments and assertions [in] a never-ending cycle." It said OneWeb is distorting its arguments to make Ku-band user terminal interference sound more likely and that OneWeb mustn't be aware of the technology in SpaceX's Starlink system that will have multiple user terminals pointing at a visible SpaceX satellite from different angles. It said that's "perhaps understandable given the substantial limitations of its own proposed system."
