As the world becomes more dependent on Global Positioning System (GPS) technology, protecting the satellite signal from jamming, computer hackers, errors and inaccuracies has become a matter of global security.

Raytheon is building the ground station for a new generation of satellites that will bring more safety and precision to GPS, affecting everything from the farms that grow our food to the warfighters that protect our freedoms to the aircraft that carry our loved ones home for the holidays.

On Thursday, May 31, Raytheon is teaming with industry partners Lockheed Martin, ITT Exelis, General Dynamics and Honeywell to convene GPS Modernization Day on the Hill, as a way to inform Congressional members, staff and other Capitol Hill stakeholders of GPS’ significance and our growing reliance on positioning, navigation and timing information. The event will feature exhibits and models demonstrating the new capabilities being developed as part of the GPS Modernization Initiative, including GPS III satellites, Next Generation Operational Control System (OCX) and Military GPS User-Equipment.

The Need for GPS Modernization
GPS is a critical, national asset—and adversaries are aggressively working to erode our GPS military advantage. Recent conflicts illustrate the growing vulnerability to GPS jamming. By 2020, advancements in spoofing and cyber attack, combined with the proliferation of jamming devices, make the current GPS system increasingly vulnerable under evolving war fighting conditions. Because nearly every military asset relies on GPS, modernizing the system has become essential to ensuring the safety, security and effectiveness of our armed forces.

The U.S. Air Force’s GPS III satellite program, the Next Generation Operational Control System (OCX), and Military GPS User Equipment are the most reliable and affordable means to sustain and modernize GPS. To ensure our soldiers can operate safely on battlefields of the future, the U.S. Air Force’s GPS modernization plan will deliver a number of critical attributes including increased accuracy, availability, anti-jam power, integrity, reliability and international interoperability.  Further, GPS modernization will be a catalyst for profound new business and economic applications, improving air traffic control, increasing crop yields, monitoring environmental trends and more, as it brings on significant capabilities.

Some key improvements include: 
  •   Higher power, jam proof military signals
  •   Increased signal and time transfer accuracy
  •   Improved Information Assurance, signal integrity and 
      cyber security
  •   New civil signal meeting US Government international
      collaboration commitments
  •   Net-centric, flexible and evolvable control system

“Raytheon couldn't be more appreciative for this opportunity to help educate our government leaders on the critical importance of modernizing the country's GPS capabilities. We are proud of our leadership role in developing and implementing the GPS-OCX ground system which is at the heart of the modernization program,” says Lynn Dugle, IIS President.
