Inmarsat-3 F4 Traffic To Start Migrating to F5 Thursday

With its Inmarsat-3 F5 satellite in orbit and to take over traffic currently carried by Inmarsat-3 F4 starting on Thursday, Inmarsat is asking the FCC International Bureau for a 60-day special temporary authorization starting that day for F5 to operate with mobile earth stations while an application to replace F4 with F5 is pending. The two satellites were last in a series of third-generation satellites and are virtually identical in design and operate in the same parameters, Inmarsat said in a set of IB filings last Thursday (see here, here and here).
