Northrop Grumman Aerospace Systems (NGAS) has selected EMS Technologies Defense & Space (D&S) to provide an anti-jam beam-forming network for the fourth advanced extremely-high-frequency (AEHF) spacecraft.
Under the $11.5m contract, EMS will deliver the nulling system, which will help in safeguarding the AEHF constellation’s Milsatcom architecture, as it is designed to protect the spacecraft’s tactical network from jamming and piracy.

EMS Defense & Space vice-president and general manager Marion Van Fosson said the products would help to provide secure communications to the warfighter.
For the AEHF programme, EMS D&S manufactures mission-critical satellite communications subsystems, including low noise amplifier assemblies, amplitude and phase weighting, power combining, switching networks and signal nulling subsystems.
The Lockheed Martin-built AEHF spacecraft are a series of communications satellites operated by the US Air Force Air Force Space Command.
