[Satellite TODAY 08-22-11] EMS Technologies’ Defense and Space division has been awarded an $11.5 million contract with Northrop Grumman Aerospace Systems to provide an anti-jam beam-forming network for the fourth Lockheed Martin-built Advanced Extremely High Frequency (AEHF) spacecraft, EMS announced Aug. 19.

   EMS’ nulling system aims to help safeguard the AEHF constellation’s military satcom architecture and is designed to protect the spacecraft’s tactical network from jamming and piracy.

   “Our products will help to provide secure communications to the warfighter … EMS’s lightweight and cost-effective nulling technology is space-qualified and it is also featured on the preceding versions of AEHF payloads. EMS has achieved gold and silver supplier ratings from Northrop Grumman for the AEHF program for several years,” EMS Defense and Space Vice President and General Manager Marion Van Fosson said in a statement.
