EMS Technologies Inc. has completed delivery of anti-jamming hardware to Northrop Grumman for installation on the payloads for the Advanced Extremely High Frequency (EHF) satellites, EMS announced July 23.

EMS Defense & Space Systems provided an anti-jamming antenna nuller called a Beam-Forming Network, which gives the satellite the ability to shape its receive beam so that jamming is ineffective. EMS delivered the technology under a five-year, $29 million contract.

The Advanced EHF program is designed to provide highly secure communications for U.S. warfighters and will provide about 10 times more communications capacity and six times higher channel data rates than its predecessor, Milstar 2. Northrop Grumman is the payload provider to prime contractor Lockheed Martin.

Launch of the first satellite is planned for mid-2008.
