Space Bureau Asks About Shutting Off SpaceX SCS Service

The FCC Space Bureau wants more detail from SpaceX about how it can shut off its mobile supplemental coverage from space (SCS) service in the event it causes harmful interference. In a letter to SpaceX this week regarding its pending modification of its second-generation satellite system authorization to allow SCS service (see 2302080001), the bureau asked (docket 23-135) how ceasing the service might potentially affect service to adjacent unserved or underserved areas. It also asked for clarification about why there is a notable difference in power levels in its U.S. and German ITU filings.
