ITT Exelis recently delivered the 500th state-of-the-art antenna that provides global positioning system (GPS) anti-jam protection for U.S. and allied militaries.

The N79 Controlled Reception Pattern Antenna, or CRPA, is used on fixed and rotary-wing aircraft, ships and unmanned platforms operating in environments with high temperatures and severe vibration.  The antenna prevents deliberate jamming and unintentional interference of timing signals when integrated with anti-jam GPS systems including the next-generation Advanced Digital Antenna Production (ADAP) and its predecessor, the GPS Antenna System-1 (GAS-1).

“Consistent GPS connections are extremely important to our fighting forces, and these antennas help ensure that link works at the most critical times. Because of our vertically integrated processes and dedicated workforce, we can rapidly respond to our customer requirements and consistently deliver a quality product.” said Mark Fournier, ITT Exelis Director of Antenna and Space Programs.

The seven-element antenna enables warfighters to navigate closer to their targets in the presence of up to six interference sources.  Exelis has been producing the anti-jam GPS antenna in its Bohemia, New York, facility since 2005.
