08 Jul 13. Northrop Grumman Corporation has taken another significant step to reduce the risks and costs associated with producing an extremely high frequency (EHF) satellite communications system for the U.S. Air Force’s B-2 stealth bomber. In a demonstration conducted May 23, Northrop Grumman proved that a new active electronically scanned array (AESA) 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. The demo included the antenna, a Navy Multi-band Terminal and the satellite. Northrop Grumman is the Air Force’s prime contractor for the B-2, the flagship of the nation’s long range strike arsenal, and one of the world’s most survivable aircraft. An EHF satellite communications system would allow the B-2 to send and receive battlefield information significantly faster than its current satellite communications system. 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 communication waveforms. The new antenna is designed to support both tactical and strategic missions. Its innovative “no radome” design allows it to bring new communications capabilities to the B-2 while maintaining the aircraft’s major operational characteristics. Earlier this year, Northrop Grumman validated the performance of the new antenna on instrumented test ranges. The tests verified the antenna’s performance over its entire transmit and receive frequency band, and over its required range of scan angles.
08 Jul 13. BAE Systems is advancing the ability of today’s warfighters to securely and reliably communicate battlefield information via jam-resistant waveforms. As the developer of the Wideband Networking Waveform (WNW) Anti-Jam (AJ) mode for the Department of Defense, the company tested its mid-tier PHOENIX™ networking radios at Joint Base McGuire-Dix-Lakehurst (Fort Dix) in New Jersey. The over-the-air test was conducted within the scope of a Cooperative Research and Development Agreement (CRADA) between the U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC), and BAE Systems. The CRADA provides industry with unique opportunities to collaboratively work alongside government engineers, allowing BAE Systems access to government facilities and resources at Fort Dix. The Product Director for C4ISR and Network Modernization — a directorate of CERDEC — provided the venue to host, instrument, and observe the BAE Systems-led tests. (Source: Yahoo!/BUSINESS WIRE)
