GSO Operators Say SpaceX EPFD Issues Make Second-Gen Approval Impossible

The evidence on record, including Viasat and Dish Network technical analyses of equivalent power flux density (EPFD), is enough to justify the FCC dismissing or deferring consideration of SpaceX's proposed second-generation constellation at least until the company modifies its plans in a way that ensures EPFD compliance, multiple geostationary orbit operators told the International Bureau Friday. Its planned second-generation constellation will exceed applicable EPFD limits in the Ku and Ka bands, "causing impermissible levels of interference" to multiple geostationary satellite networks, said EchoStar, DirecTV, Inmarsat, Dish and Viasat. SpaceX didn't comment Monday.
