Supports: Capability · maturity

Xona August3 2026 announces FCC permission for production constellation broadcasting while scheduling its first six production satellites for October. Authorization is separate from deployment and continuous global service.

Supports: Capability · maturity

Furuno September10 announces a coauthored Xona ION paper presenting numerical simulations of faster convergence under dynamic LEO visibility, potentially one-fifth to one-tenth GNSS convergence time. This is a simulation result and announced presentation, not a measured all-environment operational guarantee.
