Air Force to Battle Hostile Navigation Environments with High-Assurance GPS Receiver Technology from Rockwell Collins

Rockwell Collins has been selected by the U.S. Air Force Life Cycle Management Center (USAF AFLCMC) to provide its latest-generation Digital GPS Anti-Jam Receiver (DIGAR). With unsurpassed GPS threat protection levels, DIGAR receivers will bring highly-reliable navigation for U.S. Air National Guard and U.S. Air Force Reserve F-16 aircraft operating in contested, electromagnetic environments, according to Rockwell Collins. This will be the first combat fighter aircraft to be installed with the latest version of the receiver.

Harris Corp. Delivers Sixth GPS III Satellite Navigation Payload

Harris Corporation has provided Lockheed Martin with its sixth of 10 advanced navigation payloads contracted for the U.S. Air Force’s GPS III satellite program, the company announced today.

The GPS III navigation payload features a Mission Data Unit (MDU) with a unique 70-percent digital design that links atomic clocks, radiation-hardened processors and powerful transmitters – enabling signals three times more accurate than those on current GPS satellites. The payload also boosts signal power, which increases jamming resistance by eight times and helps extend the satellite’s lifespan.

GPS Hackers Could Send Weapons to Wrong Target – GAO Report

A recent General Accountability Office (GAO) report is highly critical of the cyber security, or lack thereof, in U.S. weapons systems. One of the examples of cyber-attacks it lists is GPS spoofing.

The report, published this month, goes on to say:

“…weapon systems are dependent on external systems, such as positioning and navigation systems and command and control systems in order to carry out their missions—and their missions can be compromised by attacks on those other systems. A successful attack on one of the systems the weapon depends on can potentially limit the weapon’s effectiveness, prevent it from achieving its mission, or even cause physical damage and loss of life.”
