The second GPS III satellite, nicknamed Magellan, has been designated healthy and usable.
According to a Notice of Advisory to Navstar Users (NANU) issued by the U.S. Coast Guard, the satellite has been designated usable as of April 1, 1945 ZULU.
The 2nd Space Operations Squadron (2 SOPS) accepted control of the Magellan on March 27 at the Schriever Air Force Base in Colorado.
Designated Satellite Vehicle Number 75 (SVN75) in the GPS constellation, Magellan is the second GPS III satellite to be accepted into the program, and the first to be accepted during a global pandemic.

“We’re continuing to make major strides even while working through this pandemic, and we continue to expand our capability to further the program along,” said Lt. Col Stephen Toth, 2 SOPS commander. “This is a huge, momentous occasion for us, that we’re reaching this milestone, that our programs are being delivered, that they’re being executed and the systems are performing as expected. Ultimately, we’re all very excited that we’ve accomplished this major milestone in the program’s history, and we’re very excited for the next things to come.”
The new generation of GPS III vehicles have a 15-year design life and signals that are three times more accurate than the current generation.
“[This means users will have] better accuracy anywhere in the world, with a user’s device being able to determine their location more reliably,” said Capt. Ryan Thompson, 2nd SOPS assistant director of operations.
Additionally, the new satellites have eight times improved anti-jam capability, allowing the military warfighter to operate better in contested, degraded and operationally limited environments.
The vehicles are designed to be forward and backward compatible, which allows them to adapt to the future while remaining fully adaptable to the previous generation of vehicles.
Eight more GPS III satellites are scheduled to launch from now until 2025.
Despite any challenges that may arise, 2nd SOPS remains focused on the mission and continues to make history in space.
“As we’ve moved forward into the Space Force, we’ve taken a bigger mindset approach toward being warfighters,” Toth said. “What COVID has actually brought out of us is the full understanding of what it is to operate with a warfighter mindset. We may not be at war with an enemy per say, but we are definitely at war with the virus. My job is to ensure we continue to provide position, navigation and timing to the world. And we take that very seriously, so despite the virus, we’ll ensure that our mission continues.”

The Space and Missile Systems Center achieved a major GPS milestone on March 27 with the Contingency Operations (COps) program and GPS III Space Vehicle (SV) 02, both of which received U.S. Space Force’s Operational Acceptance approval.
COps is an upgrade to the current GPS Operational Control System to operationally command and control GPS III satellites. These satellites are the newest generation built by Lockheed Martin, providing precise positioning, navigation and timing information with three times better accuracy, and up to eight times improved anti-jamming capability than previous generations of GPS satellites.
The first GPS III satellite, SV01, was launched on Dec. 23, 2018, and achieved Operational Acceptance on Jan. 2, 2020. USSF made SV01 available for use by military and civilian users for critical missions worldwide on Jan. 13.
Operating in a trial period since October 2019, COps supports developmental testing of the GPS III ground and space capabilities. The trial period culminated in a fully mission capable rating from the Air Force Operational Test and Evaluation Center’s Operational Utility Evaluation conducted on the new GPS III satellite and COps upgrade. This event successfully completed on Feb. 20.
Subsequently, GPS Operational Control System and COps received the second GPS III satellite — SV02, nicknamed “Magellan” — which the Space and Missile Systems Center launched on Aug. 22, 2019.
“The COps and GPS III SV02 Operational Acceptance marks another major milestone for the GPS enterprise and presents a clear picture that the Department of Defense is moving to the future,” said Lt. Col. Stephen Toth, 2nd Space Operations Squadron commander. “Of all the programs that will be delivered this year, there are few that carry with it as significant an impact to the warfighter and civilian users as this program will. This is truly a remarkable leap forward for the GPS enterprise and the capability it provides, and I couldn’t be more proud of the team that came together to make it happen.”

The Global Positioning System has provided the citizens of the United States and the world the gold standard for positioning, navigation and timing (PNT) for the past 40 years. These days, GPS is seamlessly integrated into our daily lives in ways that we hardly notice. In fact, most of us expect GPS to be available in much the same way that our lights come on when we flip a switch or water comes out when we use the kitchen faucet.
None of this is easy, however, and wouldn’t happen if it wasn’t for the incredible work and communication by the members of the GPS Program Office and our terrific enterprise partners. During the next 18–24 months, the GPS enterprise will deliver the new and more powerful modernized GPS III capabilities across all segments of the system, which have been in the works and promised for the past 8–10 years. As we transition to the Space and Missile Systems Center’s (SMC) 2.0, this is a very exciting time for the GPS program. Below are some updates on our major programs.
Program Updates
GPS III. The space segment of modernized GPS has reached our goals from 2018, and then some. SV01 “Vespucci” launched on Dec. 23, 2018, heralded by celebrations across the GPS community. The GPS III team was honored to share this event with so many giants of the GPS world. We completed space vehicle (SV) 01’s On-Orbit Checkout Test in July, meeting and exceeding all performance objectives, and plan to transfer SV01 Satellite Control Authority from SMC to the 14th Air Force by the end of the year. SV01 then begins operational testing and is expected to be certified for full operations in April 2020.
SV02 “Magellan” launched on Aug. 22 aboard a United Launch Alliance Delta IV Medium rocket — the last Delta of its class — to much fanfare and celebration as well. We completed SV02 orbit raising and initial checkout in early September, and Magellan is next in line to transition to operations in 2020.
We received delivery of SV03 and SV04 from Lockheed Martin Space Systems on May 16 and Sept. 10, respectively, with launches targeted for March and July 2020.
Challenges remain — this business is hard — but the GPS III team is focused on delivering capability: improving and streamlining the largest big-satellite production line in the Department of Defense and driving our launch campaign to bring modernized capabilities, higher power performance, and the shared international L1C signal to the GPS-using world.

GPS IIIF. The GPS III Follow-On program looks to continue the success of GPS III as it moves forward in production of the first two GPS IIIF satellites. The program is well into a year-long set of detailed design reviews projected to conclude in March 2020. With Lockheed Martin as the prime contractor for both GPS satellite programs, GPS IIIF can take advantage of production-line improvements learned from GPS III to significantly reduce assembly, integration and test timelines.
Additionally, the program is helping to shape SMC’s Enterprise Commonality Initiative: an effort focused on aligning common products and processes across multiple programs to improve quality, speed up delivery and lower costs. With plans to procure 22 satellites and a delivery timeline spanning 15 years, the program has implemented a technology-insertion strategy and partnered with the Air Force Research Laboratory to ensure a timely transition of new capabilities to meet future military requirements. It is great to see the progress GPS IIIF is making in delivering its new baseline capabilities along with the steps it’s taking toward future capability insertion. The first GPS IIIF satellite launch is forecast for 2026.
GPS Next Generation Operational Control System (OCX). This past year, we used OCX Block 0, also known as the GPS III Launch and Checkout System, to launch and initialize both GPS III SV01 and SV02 and have been flying them in caretaker status until they are ready to be incorporated into the operational constellation. On OCX Block 1, all coding is complete, and the program focus is transitioning from development to system integration, test, and then transitioning the system to operations. Program investments over the past couple of years to change the program culture and modernize the factory infrastructure (often referred to DevOps) is paying off and yielding real-time metrics used to make data-driven decisions and produce higher quality code at a significantly faster rate. As a result, OCX is no longer troubled, but is now a typical large-complex software-intensive program that will experience challenges and risks. Fortunately, the right tools are in place to deliver this critical capability.
GPS Legacy Ground Sustainment. We continue to sustain our existing GPS infrastructure associated with the current Operational Control System (OCS). These sustainment efforts ensure GPS will continue to deliver the gold standard in PNT while providing the crucial on-ramp to incorporate the next generation of modernized GPS capabilities. We operationally accepted the largest OCS upgrade in GPS history. This upgrade, known as Version 7.5, virtualized the network, implemented two-factor authentication, secured connections to worldwide ground antennas, and improved encryption for mission data.
Challenged with a need to rapidly mitigate mission risk and provide enhanced cyber protection, the Red Dragon Cybersecurity Suite (RDCSS) emerged as the GPS OCS monitoring platform, providing data aggregation, analytics and multi-level Indicators of Compromise (IOC). It has evolved into an efficient and effective means to detect, investigate, and report security events and incidents.
Additionally, in August 2019 we established an RDCSS connection into the Space Enterprise Defensive Cyber Operations (DCO) solution, known as the Cyber Defense Correlation Cell for Space. This created a layered defense and a tiered DCO environment for protecting and sustaining the GPS mission.
GPS User Equipment. Over the past year our soldiers, sailors, marines and airmen continued testing and integrating mature, next-generation GPS receiver cards that provide more accurate and reliable positioning, navigation and timing. The first
Military GPS User Equipment (MGUE) receiver card was qualified this year, and the core technologies are being leveraged to develop many other types of GPS receiver cards for a wide range of DoD weapon systems. This exciting work is the culmination of nearly two decades of modernization efforts throughout the GPS enterprise.
In the near term, we are utilizing M-code-capable lead platforms — the USAF B-2 Bomber, USMC Joint Light Tactical Vehicle, USN Arleigh-Burke Class Guided Missile Destroyer and Army Stryker combat vehicle — to prove those capabilities. The second increment of MGUE now underway will focus on requirements for precision-guided munitions, a joint common modular handheld unit, as well as circuit cards and components for low size, weight and power needs. With MGUE, the DoD and services are poised to have enduring PNT solutions the warfighter can leverage for years to come.
GPS Integration Roadmaps
Integration of modernized GPS III capabilities into our major programs is a key focus of the GPS Program Office as we deliver capabilities to our warfighter and civilians users. We have continued to refine our plans and further integrate our programs and teams to ensure a seamless transition and continued high level of service.
Enterprise Road to Launch (ERTL). The Road to Launch team achieved an historic victory of firsts in December 2018. We successfully launched GPS III SV01, the first of its class. SMC partnered with SpaceX to launch SV01 aboard a Falcon 9 rocket — their first National Security Space Launch. SV01 reached orbit under the command and control of our first GPS OCX delivery, the GPS III Launch and Checkout System.
This colossal accomplishment of firsts was only possible because of the exceptionally close integration, tenacity and highly collaborative effort among all players in the community — spacecraft, payloads, launch, control, signal monitoring, acquisition, operations, test and many others. For SV01, the ERTL has now passed the torch to the Enterprise Road to Mission team — but the Road to Launch team is as busy as ever.
The mission planners, launch and orbital operations crew ensured SV02 reached medium Earth orbit with needle-threading precision in August; the team is implementing improvements based on experience as we prepare for up to three more GPS III launches in 2020; and we are already ramping up efforts to design the launch campaign for GPS IIIF.
GPS Enterprise Road to Mission (ERM). With two GPS III satellites now on orbit, it is now time to execute the Enterprise “Integration Playbook” we have developed and coordinated over the past year. The Contingency Operations (COps) modification upgrade has now been integrated into OCS on the 2 SOPS operations floor and is undergoing Developmental Testing with the GPS III SV on orbit. The program anticipates operational testing in January 2020 and Operational Acceptance in April 2020. All of our community stakeholders are ready, and with the COps modification to OCS in place, it is time to get the GPS III satellites into mission and start providing its new capabilities to our users. Over the next few months, the GPS III capabilities are expected to be operationally certified and ready for use.
GPS Enterprise Road to M-Code Mission (ERM-M-Code). With COps now in place, the next major delivery will be M-Code Early Use modification to OCS, installation of new M-code signal monitoring equipment at sites around the globe, modification of mission planning software, MGUE Increment 1 development, service lead platform integration efforts, and operationalization of space receivers. It is our continued objective to improve the ability of the Combined Space Operations Center, to respond to urgent PNT needs of the combatant commanders as they engage more sophisticated adversaries. We remain closely aligned with our peers at USSTRATCOM, AFSPC and our worldwide users across the Joint Service and allied team.
Conclusion
It has never been a more exciting time to be part of the GPS program and enterprise. Our outstanding government and contractor teams have worked so incredibly hard on integrating and communicating our programs to ensure the successful and seamless delivery of GPS III capabilities to both our warfighter and civilian users. It is a great world we live in today, and GPS makes it even better.
GPS III Space Vehicle 02 (GPS III SV02) is complete, tested and expected to launch in 2019.
As the first Lockheed Martin-built GPS III satellite prepares to ship to the launchpad, the U.S. Air Force has declared that the second GPS III satellite is complete, fully tested and ready to launch.

The Air Force’s “Available for Launch” declaration is the final acceptance of Lockheed Martin’s second GPS III Space Vehicle (GPS III SV02), declaring it technically sound and ready to launch.
GPS III SV02 will bring new capabilities to U.S. and allied military forces, and a new civil signal that will improve future connectivity worldwide for commercial and civilian users.
GPS III SV02 now awaits official call up for launch in Lockheed Martin’s GPS III Processing Facility clean room in Denver. In June, the Air Force officially called up its first GPS III satellite for launch.
“The first GPS III satellite, GPS III SV01, was declared ‘Available for Launch’ in September 2017,” said Johnathon Caldwell, Lockheed Martin’s program manager for Navigation Systems. “It is now being prepared for shipment to Cape Canaveral, Florida, for a launch before the end of the year. With two GPS III satellites now ready for launch, and the third GPS III expected to be ready by early next year, we’re building strong momentum. These satellites will soon begin modernizing the current GPS constellation with new capabilities and more advanced technology.”

GPS III will be the most powerful GPS satellite ever on orbit. It will have three times better accuracy and up to eight times improved anti-jamming capabilities.
GPS III’s new L1C civil signal also will make it the first GPS satellite to be interoperable with other international global navigation satellite systems.
Lockheed Martin is now in full production on 10 GPS III satellites at its GPS III Processing Facility near Denver.
In June, GPS III SV03 completed thermal vacuum testing, strenuous environmental trials simulating operations in the harshest space environments. In May, the antenna deck was added to GPS III SV04, fully integrating it into a complete satellite ready to begin environmental testing.
Right behind GPS III SV04 on the production line, the fifth, sixth and seventh GPS III satellites are in component build-up. The fifth satellite has its navigation payload and is expected to be fully assembled later this summer. To date, more than 90 percent of parts and materials for all 10 satellites under contract have been received.
In April, the company submitted a proposal to the government to build up to 22 additional GPS III Follow On (GPS IIIF) satellites which would bring even further enhanced capabilities to the GPS constellation’s more than four billion users.

The U.S. Air Force’s third GPS III satellite in production flow at Lockheed Martin’s advanced satellite manufacturing facility in Denver is now fully integrated into a complete space vehicle.
GPS III Space Vehicle 03 (GPS III SV03) followed the first two GPS III satellites on a streamlined assembly and test production line. Technicians successfully integrated the satellite’s major components — its system module, navigation payload and propulsion core — into one fully assembled space vehicle on Aug. 14.
GPS III SV03 was assembled in Lockheed Martin’s GPS III Processing Facility, a $128 million, cleanroom factory designed in a virtual reality environment to drive efficiency and reduce costs in satellite production. Now fully assembled, the third satellite is being prepared to begin environmental testing.

GPS III SV03 closely follows the company’s second satellite in production flow. GPS III SV02 completed integration in May, finished acoustic testing in July and moved into thermal vacuum testing in August. The second GPS III satellite is expected to be delivered to the U.S. Air Force in 2018.
The fourth GPS III satellite is close behind the third. Lockheed Martin received the navigation payload for GPS III SV04 in October and the payload is now integrated with the space vehicle. The satellite is expected to be integrated into a complete space vehicle in January 2018.
In August, Lockheed Martin technicians began major assembly work on GPS III SV05.
All of these satellites are following Lockheed Martin’s first GPS III satellite, GPS III SV01, through production flow. In September, the Air Force accepted and declared GPS III SV01 “available for launch,” with launch expected in 2018.
“GPS III is the most powerful and complex GPS satellite ever designed and built, and it’s now into a smooth production flow,” said Mark Stewart, Lockheed Martin’s vice president for navigation systems. “The real credit goes to the Air Force for all the Back to Basics work done in advance, reducing program risk for all the GPS III satellites going forward. We are looking forward to bringing GPS III’s advanced capabilities to our warfighters in 2018.”
Lockheed Martin is under contract for 10 next-generation GPS III satellites as part of the Air Force’s modernized GPS. GPS III will have three times better accuracy and up to eight times improved anti-jamming capabilities. Spacecraft life will extend to 15 years, 25 percent longer than the newest GPS satellites on-orbit today. GPS III’s new L1C civil signal also will make it the first GPS satellite to be interoperable with other international global navigation satellite systems.
Lockheed Martin’s unique GPS III satellite design includes a flexible, modular architecture that allows for the insertion of new technology as it becomes available in the future or if the Air Force’s mission needs change. Satellites based off this design are already proven compatible with both the Air Force’s next generation Operational Control System (OCX) and the existing GPS constellation.
The GPS III team is led by the GPS Directorate at the U.S. Air Force Space and Missile Systems Center. Air Force Space Command’s 2nd Space Operations Squadron (2SOPS), based at Schriever Air Force Base, Colorado, manages and operates the GPS constellation for both civil and military users.
