Startup Xona Seeks OK for 258-Satellite PNT Services Constellation

California-based startup Xona Space Systems seeks FCC authorization to launch a 258-satellite radionavigation satellite service in low earth orbit. In an Office of International Affairs application Tuesday, Xona said the aim is to provide centimeter-level positioning, navigation and timing services for U.S. and international markets using the L and C bands. It said it anticipates launching 60 satellites a year to replenish its aging ones.
