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
GPS is a critical, national asset with increasing global dependence. Declared operational in 1995, the U.S. Air Force’s GPS has become an integral tool, one the U.S. military relies on to keep troops safe and one businesses depend on to improve productivity and efficiency.
Adversaries are aggressively working to mitigate our GPS advantage. By 2020, advancements by potential enemies in jamming, spoofing and cyber attack make the current GPS system increasingly vulnerable under evolving war fighting conditions. Investments in U.S. weapons systems and war fighting strategies leveraging space-based Position, Navigation & Timing (PNT) are at stake.
To ensure the U.S. maintains its military advantage and leadership, the U.S. Congress authorized a GPS enterprise modernization project in 2000, commonly known as GPS III, to maintain and upgrade existing GPS capabilities. The project involves new, more capable satellites and a flexible, secure control system that together will provide new navigation signals for both civilian and military users, and will improve accuracy, availability and resistance to intentional jamming.
To guarantee our warfighters successfully complete missions and operate safely on battlefields of the future, the U.S. Air Force’s modernization plan will deliver advanced capabilities and enhance the overall performance of GPS.
Some key improvements include:
- Higher power, jam proof military signals
- Increased signal and time transfer accuracy
- Improved Information Assurance, cyber security and improved aviation signal integrity
- New civil signal meeting U.S. Government international collaboration commitments
- Adaptable spacecraft bus for low-risk affordable capability insertion in the future
- Net-centric, flexible and evolvable control system
Additionally, GPS has become a global utility that not only military users depend on, but civil and commercial users rely on daily for critical position, navigation and timing (PNT) information. GPS modernization will be a catalyst for profound new business and economic applications, improving air traffic control, increasing crop yields, monitoring environmental trends, employing millions of Americans and so much more. The new advanced capabilities offered by GPS Modernization including increased accuracy, availability, anti-jam power and international interoperability will impact the following applications:
- Public Safety and Disaster Relief
- Surveying and Mapping
While the primary focus of the U.S. Air Force’s GPS modernization plan is the addition of new navigation signals, GPS technology enables commercial users to benefit from greater precision, accuracy and timing information, which result in fuel savings, productivity and time savings, as well as improved public safety and national security.
Today, more than 3.3 million jobs rely on GPS technology. According to the U.S. Department of Commerce, the new L2C signal, part of the GPS modernization efforts designed to meet commercial needs, will likely generate more than $5.8 billion in user productivity gains over a 30 year timeframe.
Existing performance limitations and the emergence of growing cyber threats drive the need for GPS modernization and Next Generation Operational Control System (OCX) to ensure continued access to this global utility.
Raytheon is building the control segment that will operate the next generation of GPS satellites. GPS OCX will upgrade the existing legacy system. OCX is the next generation operational gateway service designed to provide secure, accurate and reliable navigation and timing information to effectively support military, commercial and civil users. GPS OCX will be the service integrator between ground, space and user segments to enhance mission command and control, and situational awareness capabilities, while seamlessly supporting billions of users around the world.
OCX will be developed in an incremental fashion that will deliver capabilities to the field and the required growth and flexibility to meet military and civil needs for the next 30 years.
Future OCX capabilities include enhanced space launch support, increased situational awareness for GPS operators and support for future satellite blocks with advanced capabilities such as new signals, NAVWAR capabilities, high-speed cross-links and additional payloads.
OCX segment updates GPS command and control (C2) and mission management capabilities, transforming the focus of GPS operations from satellite C2, to user-oriented, effects-based operations. In addition, GPS OCX will facilitate additional civil signals (L1C, L2C and L5) and new signal structures (M-Code) to provide navigation integrity, improved accuracy and increased availability.
OCX is built on a secure, service-oriented architecture that provides:
- Command, Control and Mission Management for all GPS II and III spacecraft (GPS IIR-M, IIF and GPS III)
- Control of all GPS signals, including modernized signals (M-code, L1C, L2C and L5)
- Robust Information Assurance to protect against evolving cyber threats
- Ability to plan and execute GPS NAVWAR missions
- Reduced sustainment costs through automation and efficient software architecture
- Flexibility to accommodate new functionality and evolving CONOPS
- Net-ready and Global Information Grid compliance to ensure warfighters have access to secure, valuable real-time system information
The GPS OCX program meets and addresses the challenges facing GPS with a flexible, adaptable and modular architecture based on service-oriented principles. Its modern capabilities will be the cornerstone for revolutionizing GPS command and control (C2) mission ability and evolve global position, navigation and timing services to meet the current and future needs of civil, commercial and military users worldwide.
