Northrop Grumman Tests First Airborne Ka-Band Satellite

May 25, 2010

Northrop Grumman Corporation /quotes/comstock/13*!noc/quotes/nls/noc has successfully completed flight testing of an airborne satellite communications system, part of a network that will significantly enhance communications capabilities for warfighters. This represents the first airborne terminal system to be certified for connection to the Wideband Global Satellite (WGS).

The flight test used the communications terminal system installed on a modified business jet aircraft to connect with a WGS via the Ka-band link. The test -- which measured terminal performance including high data rates -- is the second of three phases required to certify the airborne communications system for WGS operations.

"This is a tremendous step forward in realizing the objective of a redundant, robust and multi-layered approach to airborne communications and ISR (intelligence, surveillance and reconnaissance) dissemination that our senior leaders and warfighters deserve. It was really a superb joint effort involving close Army, Navy and Air Force cooperation and partnerships throughout the test phases," said Craig Lucas, program director for the U.S. Army Communications-Electronics Research, Development and Engineering Center (CERDEC).

Northrop Grumman is performing the certification under the Multi-Role Tactical Common Data Link (MR-TCDL) Developmental and Operational Test program contract. The MR-TCDL system provides combat personnel with critical real-time networking connectivity by enabling extremely fast exchange of data via ground, airborne and satellite networks.

"MR-TCDL's ability to dynamically route IP data seamlessly between space, aerial and ground layers is why it's the centerpiece of joint aerial layered networking concepts. This successful demonstration of airborne Ka access is critical to achieving this end," said Dave Gay, global communications division chief for U.S. Strategic Command.

The Defense Micro-Electronics Activity awarded the 30-month, $69 million MR-TCDL contract to support CERDEC.

The WGS satellites are elements of a system that increases U.S. communications capabilities, supporting the U.S. Department of Defense's war-fighting information exchange requirements, enabling execution of tactical command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR); battle management; and combat support information. The Ka-band WGS link uses a less-congested frequency band than other satellites and enables high data-rate information assimilation by airborne and ground-based terminals.

Northrop Grumman's teammates on the program include U.S. Strategic Command, Offutt Air Force Base, Neb.; L-3 Communications South West, Salt Lake City, Utah; Alpha Research & Technology Inc., El Dorado Hills, Calif., and Orion Air Group, Tucson, Ariz.
