EL SEGUNDO, Calif., Oct. 10 /PRNewswire/ -- Raytheon Company has been
awarded two contracts to develop the next-generation anti-jam technology for
militarized Global Positioning System (GPS), the first step in production of
the Digital Antenna Electronics (DAE) program for all Department of Defense
aircraft.
Raytheon's Precision Guidance Systems (PGS) organization was awarded a
$1.9 million option to its Digital Antenna Electronics (DAE) contract with the
U. S. Navy's Space & Naval Warfare Systems Center for GPS anti-jam research
and development. The contract modification authorizes Raytheon to develop,
produce, and test DAE prototypes that are compatible with standard aircraft
anti-jam antenna systems in preparation for competitive procurement of
production DAE units. The DAE production effort is valued at $25 million.
Raytheon Systems Limited, a Raytheon Company located in the United
Kingdom, has been awarded the other DAE contract option to continue
development of an alternative design.
"DAE will offer a major near term improvement to the current analog
standard until fully digital solutions are developed," said Dimitri Theodorou,
director of Raytheon PGS. "It will provide anti-jam protection superior to
that achieved with existing analog systems, through the combination of
innovative architectures, null-steering /limited beam-forming, and advanced
signal processing techniques."
The DAE will be compatible with current military receivers and will be
capable of functioning with both the current and future modernized GPS signal
structures, such as M-code and spot beam modes.
Precision Guidance Systems, an organization within Raytheon's Space and
Airborne Systems (SAS) business, designs and develops GPS Selective
Availability Anti-Spoofing Module receivers, integrated navigation systems for
weapons, hand held GPS products, airborne multi-mode receivers, and
specialized naval guidance products. PGS is the industry leader in GPS anti-
jam solutions, including analog and digital adaptive antenna systems and
ultra-tight coupled GPS/INS systems.
With headquarters in Lexington, Mass., Raytheon Company (NYSE: RTN) is a
global technology leader in defense, government and commercial electronics,
and business and special mission aircraft.
Information for Editors on GPS Anti-Jam Technology
GPS is widely used as a source for position, velocity, and time
information on U. S. military platforms. However, the GPS signal is of low
power and vulnerable to interference. Threats range from cheap, expendable,
low-power jammers that can be widely distributed across an area of conflict,
to medium and high-power ground and air-based jammers that can deny usage of
GPS over hundreds of miles. The GPS Joint Program Office established the
Navigation Warfare (NAVWAR) program in 1996 to address the electronic warfare
threat to the GPS system. The NAVWAR program was tasked with protecting DoD
and allied use of GPS during times of conflict, preventing its use by
adversaries, and maintaining normal availability to the civil user outside the
area of conflict.
The primary near-term solution to meet NAVWAR objectives involves fielding
anti-jam antenna systems on weapons platforms. The present anti-jam antenna
system in production, GPS Antenna System-1 (GAS-1), is an analog system with
anti-jam capability limited to the formation of spatial nulls in the direction
of interference. Over 1,000 units of the GAS-1 have been produced by Raytheon
Systems Limited, in Harlow, UK. The GPS roadmap for user equipment
anticipates a fully digital receiver with nulling/multi-beam steering as a
long term solution. DAE offers a major near term improvement by using digital
signal processing to enhance jammer suppression by providing a limited beam
steering capability to assist in filtering out jammer noise, while preserving
the current GAS-1 AE form, fit, and interfaces.
