The U.S. Space Force has been steadily upgrading its existing GPS Ground Operational Control System (OCS). It has announced Operational Acceptance of the GPS Contingency Operations (COps) upgrade, developed by Lockheed Martin. COps enables control of the operational GPS constellation, now containing 21 M-Code capable GPS satellites, including Lockheed Martin’s first two GPS III satellites until the next generation OCX ground control system is delivered. The final steps to fully-enable the ultra-secure, jam-resistant Military Code (M-Code) signal on the Global Positioning System (GPS) are now underway.
M-Code operational availability on track for 2020
The Space Force’s M-Code Early Use (MCEU) upgrade, delivered earlier this year, will enable the OCS to task, upload and monitor M-Code within the GPS constellation, as well as support testing and fielding of modernized user equipment, prior to the completion of the next-generation ground control systems.
This spring, work will begin to install the components needed to command and monitor the M-Code encrypted GPS signal, which enhances anti-jamming and protection from spoofing, as well as increases secure access for our forces, into the GPS OCS. M-Code signals are currently available on all the on-orbit GPS IIR-M, IIF and III space vA key to enabling M-Code is a new software-defined receiver Lockheed Martin developed and is installing at all six Space Force monitoring sites. The M-Code Monitor Station Technology Capability (M-MSTIC) uses a commercial, off-the-shelf general-purpose Graphics Processing Unit (GPU) to cost-effectively receive and monitor M-Code signals. Operators can monitor the signal as needed. M-MSTIC complements MSTIC’s, which Lockheed Martin developed and fielded to replace aging hardware receivers that were becoming difficult and expensive to maintain.
Warfighters depend on GPS signals every day for many critical missions, so anything to make these signals more resistant to jamming and spoofing is extremely important – and available today. The more powerful GPS III/IIIF satellites coupled with Lockheed Martin’s upgrades to the GPS ground system are making that possible.
Second GPS III satellite joins GPS Constellation
On March 27, the Space Force declared Operational Acceptance of Lockheed Martin’s second GPS III satellite. Another M-Code enabled satellite, GPS III Space Vehicle 02, “nicknamed Magellan,” is modernizing today's GPS satellite constellation with new 3x greater accuracy and up to 8x improved anti-jamming capabilities. GPS III also provides a new L1C civil signal, compatible with other international global navigation satellite systems, like Europe's Galileo.
Lockheed Martin is currently contracted to build up to 32 GPS III/GPS III Follow On (GPS IIIF) satellites to help modernize the GPS constellation with new technology and advanced capabilities. The delivery tempo for these modernized GPS satellites will allow for several launches per year. The third M-code enabled GPS III satellite, named “Columbus,” is expected to launch in April 2020.
Cybersecurity significantly hardened with Red Dragon Cyber Security Suite
Cyber defenses across the upgraded GPS system were recently evaluated by a government assessment team and passed the Operational Utility Evaluation. Lockheed Martin delivered the Red Dragon Cybersecurity Suite (RDCSS) Phase III upgrade during the fourth quarter of 2019, dramatically improving Defensive Cyber Operations (DCO) visibility into GPS network traffic. Other add-ons include user behavior analytics to analyze patterns of traffic and network taps to improve data collections.
Lockheed Martin has sustained the GPS Ground OCS since 2013. In November of 2018, the team completed the AEP 7.5 architectural change – replacing the hardware and software to improve resiliency and cybersecurity. In December of 2018, the Air Force awarded Lockheed Martin the GPS Control Segment Sustainment II (GCS II) contract to further modernize and sustain the AEP OCS through 2025.
The GPS III team is led by the Production Corps, Medium Earth Orbit Division, at the Space Force's Space and Missile Systems Center, at Los Angeles Air Force Base. The GPS OCS sustainment is managed by the Enterprise Corps, GPS Sustainment Division at Peterson Air Force Base. 2 SOPS, at Schriever Air Force Base, manages and operates the GPS constellation for both civil and military users.
