Air Force Receives Aircraft Self Protection Security System

April 20, 2006

Raytheon's near object detection sensor technology protects aircraft from a variety of threats.


TEWKSBURY, Mass. /PRNewswire/ -- Raytheon Company's Integrated Defense Systems (IDS) business recently delivered to the Air Force the first of an Aircraft Self Protection Security System (ASPSS). Using near object detection sensor (NODS) technology, the system provides electronic perimeter security for aircraft parked on the tarmac of an airfield or in a field location.

Raytheon also has developed the Vigilant Eagle Airport Protection System, which protects airplanes from man-portable air defense systems threats during takeoffs and landings. The two systems are complementary: Vigilant Eagle provides security for active aircraft, and ASPSS protects parked aircraft.

The four-sensor version of ASPSS is a low-cost, portable system the Air Force recently accepted after tests at Eglin Air Force Base, Fla., under a $2.1 million cost-plus-fixed-fee contract administered by the Electronic Systems Center, Hanscom Air Force Base, Bedford, Mass.

"This aircraft self protection security system warns of potential close proximity threats to aircraft parked on the ground," said Mark Russell, Raytheon IDS vice president of Engineering.

The NODS technology consists of three components: a near object detection sensor the size of a book, a communications module, and a personal digital assistant (PDA)-like alarm and display device. The near object detection sensor and communications module are mounted on a tripod and placed around the parked aircraft. The PDA-like display unit and another communication module, together known as an annunciator, are carried by security personnel. Each near object detection sensor covers approximately a 120-degree arc and is able to detect the presence of people and vehicles out to 100 m and beyond.

Four sensors can provide overlapping 360-degree coverage of a single aircraft, and more sensors can be arranged to cover multiple aircraft parked together.

According to Russell, Raytheon IDS will be delivering a three-sensor solution to the Air Force in the near future and a multiple aircraft version in late summer.

In addition to aircraft protection, the technology shows promise for fence line, fixed facilities, and commercial applications where cleared zone security is a consideration, Russell said.

Integrated Defense Systems is Raytheon's leader in Joint Battlespace Integration, providing affordable, integrated solutions to a strong international and domestic customer base, including the U.S. Missile Defense Agency and the U.S. armed forces.

Raytheon Company, with 2005 sales of $21.9 billion, is an industry leader in defense and government electronics, space, information technology, technical services, and business and special mission aircraft. With headquarters in Waltham, Mass., Raytheon employs 80,000 people worldwide.
