Five companies will continue to provide Inmarsat mobile satellite services to U.S. military and other government customers under contracts with a combined potential value of $65.7 million, according to a June 11 Pentagon announcement.

The companies are: ADCI of Delaware LLC of Chevy Chase, Md.; AOS Inc. of Dallas; CapRock Government Solutions of Fairfax, Va.; Global Communications Solutions Inc. of Victor, N.Y.; and O’Gara Satellite Systems Inc. of Rancho Palos Verdes, Calif.

Each contract has one base year with a one-year option, and all work is scheduled to be completed by June 5, 2014, according to the contract announcement. The indefinite-delivery, indefinite-quantity contracts were awarded on a sole source basis to the five incumbent companies.

The mobile satellites services to be provided under the contracts will support land, maritime and aeronautical communications, according to the announcement. London-based Inmarsat operates a global constellation of satellites in geostationary orbit that provide mobile services in L-band frequencies.
