GPS & Navigation Systems (GNS)

An Industry Leader in Military GPS Solutions

GPS & Navigation Systems (GNS) acts as the Center of Excellence to coordinate military GPS user equipment efforts for Raytheon Company. GNS offers the most advanced military GPS user equipment available, including avionics, high anti-jam systems, integrated GPS/INS navigators, and high performance Selective Availability Anti-Spoof Module (SAASM) receivers.

GNS capabilities include:

  • Front-end system analysis and modeling
  • Design, development, and integration
  • Functional, performance, and environmental testing
  • High-reliability production
  • Depot maintenance
  • World-class test and evaluation facilities

In addition to navigation systems, Raytheon produces a full line of anti-jam products designed to keep signals secure.

Avionics GPS Systems

Miniature Airborne GPS Receiver (MAGR) 2000 and MAGR 2000 SSAAM

The MAGR 2000 design is a GPS Receiver Applications Module (GRAM) based open system architecture that is modular in design and incorporates modern electronics. The MAGR 2000 is a form, fit, and function backward compatible replacement of the MAGR, and provides enhancements including improved acquisition and GPS solution performance, all-in-view GPSsatellite tracking and GPS integrity.

MAGR 2000 includes a SAASM upgrade.

High A/J GPS Systems

Advanced GPS Inertial Navigation Technology (AGINT)

Raytheon was selected by AFRL to develop an affordable, small, anti-jam GPS receiver system using frequency spatial time adaptive processing (FSTAP). The AGINT design has a multi-element RF front end, digital adaptive A/J filter, and SAASM GPS receiver.

In Phase I, Raytheon demonstrated a breadboard to show the feasibility of the proposed AGINT processing concept and technology.

The Phase II effort developed a brassboard, which is capable of 120 dB of jamming protection against multiple broadband and narrowband jammers, and can provide beamsteering to four separate GPS satellites.

Integrated GPS/INS Systems

GPS-Aided Inertial Navigation System (GAINS)

GNS has extensive experience in developing integrated GPS/INS systems.

The GAINS is implemented with an open architecture and modular design such that the system is easily tailorable to individual platform requirements for high accuracy, precise positioning service and all-weather GPS guidance. GAINS provides blended GPS/INS guidance for: the EGBU-15 glide bomb, the Enhanced Paveway® II laser-guided bomb, the SM-3® interceptor, the Paveway IV precision-guided bomb, and the MALD® Miniature Air-Launched Decoy.

Receiver Module Products

Raytheon Advanced Protection Technology Receiver (RAPToR-III)

The RAPToR common weapon receiver represents the most capable military GPS technology presently available. Features such as 24 channels of simultaneous L1/L2 tracking, patented Direct Measurement Processing (DMP), ultra-t GPS/INS coupling, innovative fast satellite acquisition, and the smallest SAASM device in existence are unique to Raytheon.

Modernized User Equipment (MUE)

GNS has been awarded an MUE Receiver Card development program contract to design the next generation of military GPS receivers. Using advanced microelectronics and breakthroughs in security solutions, the end result of this effort will be a family of high-performance, low cost M-code GPS user equipment.
