Lockheed Martin demonstrated that the U.S. Navy's Mobile User Objective System (MUOS) satellites may help solve communication challenges in the arctic. Now people spread over thousands of square miles could have access to more secure, reliable communications. During company-funded tests, MUOS voice and data signals reached much farther north than previously thought, just 30 miles and 0.5 degrees of latitude shy of the North Pole.

A team demonstrated Wideband Code Division Multiple Access (WCDMA) capability using three different radios as far north as 89.5 degrees, under peak orbit conditions. This inherent voice and data access is well beyond the 65-degree system requirement. The additional coverage comes at a time when demand is surging for dependable polar communications.

The demonstrations show MUOS has an advantage over legacy satellite communications. Lockheed Martin performed two rounds of testing late last year aboard an L-100 aircraft, the commercial variant of the C-130 Hercules. Multi-hour flights set out from Barrow, Alaska to test transmit and receive capabilities.

Three terminal providers developing MUOS-compatible radios were on board, including the General Dynamics PRC-155 Manpack, the Harris PRC-117G Manpack and the Rockwell Collins ARC-210 V5 airborne terminal. Anticipated shipping lanes will see full coverage 24 hours a day, with signal gradually dropping off farther north to 89.5 degrees, which can be achieved at peak orbit conditions. Airborne terminals can connect further north than sea level terminals, but at reduced durations.
