Antennas: EMS Defense & Space to supply SATCOM antenna for Army RC-12

Military communications experts at Science Applications International Corp. (SAIC) in McLean, Va., needed an X-band satellite communications (SATCOM) antenna system for the U.S. military RC-12 signals-intelligence aircraft. They found their solution at EMS Defense & Space in Norcross, Ga.

Satellite antenna designers at EMS Defense & Space will provide SAIC with an X-band SATCOM antenna system by converting the EMS Wavestorm GS-X antenna to an airborne version, called the Wavestorm AS-X. The RC-12 aircraft is a military version of the Beechcraft Super King Air 200 twin-engine turboprop.

EMS will provide the slot array antenna aperture, antenna control unit, positioner, RF electronics, autonomous navigation and stabilization, and installation support. EMS engineers developed the Wavestorm GS-X antenna to support wideband communications requirements for systems transmitting across X-band satellites. The antenna’s low-profile slot-array technology is designed for high-bandwidth data transmission. EMS demonstrated the antenna system in the U.K. over the Skynet 5 satellite constellation by transmitting full-motion video at data rates as fast as 14 megabits per second.
