On Thursday, SpaceX made the accusation in a FCC filing defending the company’s proposal for a second-generation Starlink network, which aims to one day supply high-speed internet to millions of users across the globe. Viasat has been among the rival satellite providers demanding the FCC impose certain conditions on the proposal, citing concerns the second-gen Starlink network will cause radio interference and collisions in space. However, SpaceX claims Viasat is resorting to legal tactics to both delay the second-gen Starlink network and to also uncover proprietary data about it.

Viasat didn’t immediately respond to a request for comment. But earlier this month, it told the FCC that SpaceX’s application for the second-gen Starlink network failed to provide “key antenna and transmission information about its proposed system expansion,” including the number of beams on each satellite, and the channels per beam.

In an email, Viasat told PCMag it's only asking that SpaceX be required "to provide basic information under longstanding FCC policies and to substantiate SpaceX’s unsupported assertions in its application." "That data is needed to ensure that SpaceX actually can share spectrum and operate in a safe manner. It speaks volumes that SpaceX refuses to back its broad assertions with facts and other data," Viasat added. Get Our Best Stories!
