GPS Receivers Resist Jammers

A rugged GPS receiver developed for the U.S. Air Force is resistant to jamming signals.

GPS satellites and their signals provide guidance and precision location information for many users, including the U.S. Air Force. Fighter pilots and others depend on the accuracy and reliability of those satellite signals. To ensure improved performance with their GPS systems, Rockwell Collins recently fulfilled an order for a 770 Military-Code (M-Code) GPS receiver for the USAF’s Space and Missile Systems Center (SMC), with hardware designed for fifth-generation aircraft. The latest receivers (see photo), which are committed to the Military GPS User Equipment (MGUE) program, are specifically designed to provide high resistance to jamming signals.

An M-Code GPS receiver is designed to be resistant to jamming signals.

“From advanced fifth-generation aircraft to ground and maritime applications, this technology meets the warfighters’ needs for reliable and secure GPS navigation for increased situational awareness,” said Troy Brunk, vice president and general manager, Communication, Navigation & Electronic Warfare Systems for Rockwell Collins. “This delivery demonstrates a major advancement in military technology.”

The M-Code systems are designed to provide increased GPS performance for military users, at the same time co-existing with civilian or conventional military GPS receivers. M-Code receivers can be applied to new and retrofitted platform and provide autonomous operation, meaning that a user can calculate position by comparing M-Code signals to existing signals when more than one signal code is required.
