  • Raytheon completes qualification testing of GPS launch and checkout system

    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.

    Raytheon has reached another milestone in its development of the U.S. Air Force’s Global Positioning System Next Generation Operational Control System, known as GPS OCX. This new system offers significant improvements to the GPS on which the U.S. military and millions of civilians rely, including enhanced availability, accuracy and security.

    OCX’s development is delivered in “blocks,” with Block 0 comprising the Launch and Checkout System to take GPS III satellites into early orbit. Block 1 is built on Block 0 and delivers the full OCX capability, which allows the Air Force to transition from its current GPS ground controls to the modernized and secure GPS OCX master control station.

    Raytheon recently completed a series of Risk Reduction functional checkouts of OCX Block 1 capabilities, with a focus on OCX software. This latest development activity integrated iteration 1.5 of the OCX Block 1 Master Control Station with the GPS System Simulator and ran operational scenarios, representing the first end-to-end integration of available Block 1 capabilities. The testing included GPS constellation management and sustainment, demonstrating OCX’s abilities for precision navigation and timing capabilities in a fully cyber-hardened environment.

    The test included running Kalman filters and generating GPS satellite navigation uploads. The completion of the Risk Reduction functional checkout informs and benefits future OCX development efforts. Future development will add to the existing capability and expand capability to include both the civil and military modernized signals.

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

    GPS OCX provides a number of significant modernized capabilities for GPS users, including robust cybersecurity and deployment of jam-resistant, operational military code, or M-code. The OCX Launch and Checkout System provides an early delivery of much of the overall block 1 OCX capability, and will support the GPS III satellite launches.

  • Raytheon GPS Ground Program Passes Review

    The ground control system (OCX) that Raytheon is developing for the next-generation GPS program has passed a Pentagon review, reports Reuters. The program will be monitored to ensure it stays on track, a senior Air Force official said on Feb. 6 as reported by the news service.

    Major General Roger Teague, director of space programs for the Air Force acquisition chief, said a review by chief arms buyer Frank Kendall went well, but program officials and the contractor got “tough marching orders” to stick to schedule and cost targets.

    Raytheon’s program manager Matt Gilligan said the review provided the company with “clear direction, the best technology, and appropriate resources to…deliver OCX on a schedule that meets GPS enterprise needs.”

    Kendall had ordered the review after an Air Force restructuring that increased the cost of the program by 80 percent to $1.6 billion.
