New satellite communications antenna for B-2 stealth bomber
a demonstration conducted May 23, Northrop Grumman proved that a new
antenna it has developed for the B-2 can establish and maintain
communications services with an on-orbit Air Force Advanced EHF
(AEHF) communications satellite.
new active electronically scanned array (AESA) antenna and EHF
satellite communications system would allow the B-2 to send and
receive battlefield information significantly faster than its current
satellite communications system.
demo marks the first time that AESA antenna technology has been used
to communicate with the AEHF network," said Byron Chong,
Northrop Grumman's B-2 deputy program manager. During the test, he
added, Northrop Grumman successfully demonstrated extended data rate
(XDR) communications between the AESA antenna and the AEHF satellite
at EHF frequencies. XDR communications take advantage of the AEHF
satellites' most advanced, most secure signaling protocols and
