Raytheon reached another milestone in developing the GPS Next-Generation Operational Control System, known as GPS OCX, with the completion of the factory qualification test of the Launch and Checkout System (LCS).

GPS OCX will enable dramatically increased performance and security of the GPS system that benefits millions of people worldwide.

Raytheon tested 74 OCX segment requirements at its Aurora, Colorado, factory in a cyber-hardened environment, verifying that the LCS is well on its way to meeting U.S. Air Force requirements.

Next, the remaining OCX segment requirements will be qualified in a retest period, and those requiring external interfaces will be qualified onsite at Schriever Air Force Base before delivery of the overall OCX LCS in 2017.

The final phase of testing — Site Acceptance Testing — will follow the delivery of the system.

“The completion of the Factory Qualification Test proves we can meet the U.S. Air Force requirements and are on a path to delivering the OCX LCS in 2017,” said Bill Sullivan, vice president and program manager for Raytheon’s GPS OCX. “This critical system will enable the launch of the GPS III satellites, which represents the first major capability deployment in the U.S Air Force’s effort to modernize GPS.”

The Factory Qualification Test achievement builds upon other OCX milestones achieved in 2016, including:

  • Completion of Black Wide Area Network testing of unclassified external interfaces for GPS OCX with perfect scores on mission capability and cyber controls
  • 100 percent requirements pass rate on Electro-Magnetic Interference testing on the OCX Monitor Station Receiver Element, or OMSRE
  • Successful Critical Design Review for OMSRE hardware development
  • Completion of the LCS component-level qualification test
  • Risk-reduction testing functional checkout for the OCX ground system software, demonstrating OCX’s capabilities for precision navigation and timing in a fully cyber-hardened environment

The U.S. Air Force-led GPS Modernization Program will yield new positioning, navigation and timing capabilities for U.S. military and civilian users across the globe. Developed by Raytheon under contract to the U.S. Air Force Space and Missile Systems Center, GPS OCX is replacing the current GPS operational control system and will support the launch of the GPS III satellites.

The new system will provide enhanced performance, the effective use of modern civil and military signals and secure information-sharing with unprecedented cyber protection.
