WASHINGTON — Two of the world’s largest geostationary satellite fleet operators said March 10 that launch providers who compete with them by deploying their own constellations could influence their choice of rockets.

Executives from SES and Eutelsat at the Satellite 2020 conference here said they are watching as SpaceX deploys its own Starlink constellation of broadband satellites, which could make SpaceX one of their competitors.

Blue Origin could also become a competitor if it launches Amazon’s Kuiper broadband constellation, according to Eutelsat Deputy CEO Michel Azibert and Hughes President Pradman Kaul, since Jeff Bezos owns both Amazon and Blue Origin.
