Inmarsat experienced an outage on its I-4 F1 satellite, which provides L-band services for East Asia and the Pacific region, at 21.14 UTC on Sunday 16 April. This resulted in the temporary loss of services from the satellite and the company immediately instigated its recovery procedures.
Safety services are being prioritised and Inmarsat can confirm that immediately following the incident, it instigated the process to transfer maritime safety services, in line with the IMSO approved operational process to a contingency satellite. That process was completed successfully.
Inmarsat Classic Aero recovery has now started and is expected to be operational in a matter of hours. This will be followed by the transfer of Inmarsat-C services from the contingency satellite back to I-4 F1 and then a focus on the restoration of other services.
All other satellites in the L-band fleet are unaffected by the incident. This includes Inmarsat’s two new L-band satellites – I-6 F1 and F2 – which will be joined in 2027 by a further three new micro L-band satellites, the Inmarsat-8s, specifically designed to enhance safety service back-up for L-band customers.
