    The United States Space Force’s Space Systems Command (SSC) has a specialized branch responsible for certifying GPS accuracy called the GPS Certification Branch. It is a specialized team within SSC that is responsible for certifying the hardware, software, and firmware used in GPS-based systems.

    The certification process conducted by SSC’s GPS Certification Branch involves the evaluation of design and testing for various components of GPS-based systems. This includes user equipment — the devices used by individuals or organizations to receive GPS signals and determine their precise location.

    The GPS Certification Branch works with GPS manufacturers, agencies of the U.S. Department of Defense (DOD), and others to establish and maintain certification standards. Collaboration with industry experts, research institutions, and other certification bodies is also an important aspect of the branch’s work to stay informed about technological advancements and ensure the certification process remains up to date with the latest developments.

    The certification process also includes space segments — the satellites that transmit the GPS signals, monitoring stations, which track and monitor the performance of the GPS satellites, and the terrestrial modules — that provide end user secured and accurate signals.

    Certification of hardware, software, and firmware is critical to ensure that GPS systems meet the standards set by the DOD. This certification ensures that the GPS-based systems used by the military and other DOD agencies are reliable, accurate, and secure. It also ensures that they are interoperable and compatible with other military equipment and communication networks.

    The assessment process conducted by the GPS Certification Branch involves thorough testing and analysis of the design, performance, and security of the GPS components. This includes assessing the hardware’s ability to receive and process GPS signals accurately, the software’s ability to interpret and utilize the GPS data effectively, and the firmware’s ability to maintain system integrity and security.

  • Final GPS III satellite available for launch

    Space Systems Command (SSC) has declared GPS III Space Vehicle 10 (SV10) available for launch, marking completion of constellation modernization efforts and production for the GPS III program.

    “The completion of the tenth, and final, GPS III space vehicle is a significant milestone for GPS modernization,” said Scott Thomas, GPS III program manager for the GPS Space Vehicles Acquisition Delta within SSC’s Military Communications and PNT directorate. “This would not have been possible without the collaboration, communication, and accountability of our industry and government partners. The GPS III program contributions underpin U.S. national security needs for our warfighters and for more than four billion GPS users worldwide.”

    GPS III satellites deliver enhanced performance and accuracy through a variety of improvements, including increased signal protection with improved accuracy. GPS III also delivers a new L1C signal designed for interoperability with similar GNSS, and expands the civilian L5 signal, dubbed safety-of-life, which is not yet operational.

    GPS III SV06 was launched on a SpaceX Falcon 9 Block 5 vehicle on Jan. 18, and Operational Acceptance was declared on Jan. 31. GPS III SV07, SV08, SV09 and SV10 are awaiting launch at Lockheed Martin’s GPS III processing facility in Waterton, Colorado.

    Space Force orders 3 more GPS IIIF satellites from Lockheed

    The three new GPS satellites will be delivered under the third production option of the GPS III contract

    Space Systems Command (SSC), a division of the U.S. Space Force, has exercised its third production option valued at $744 million for the procurement of three additional GPS III Follow-On satellites from Lockheed Martin.

    The contract option covers GPS IIIF Space Vehicles (SVs) 18, 19 and 20.

    GPS IIIF will provide several next-generation capabilities to meet increased demands of both military and civilian users. Building on the technical baseline of satellites 01 to 10, the newer satellites will provide increased anti-jam capabilities for the military with the addition of a Regional Military Protection capability.

    Precision ranging measurements will be enabled by a laser retro-reflector array and will address the consolidation of telemetry, tracking and commanding frequencies.

    Additionally, GPS IIIF leverages major international collaboration with the Canadian Department of National Defense and other U.S. government organizations such as the National Oceanic and Atmospheric Administration, the Air Force Rescue Coordination Center, and the U.S. Coast Guard Office of Search and Rescue (SAR) by hosting a new SAR payload.

    This payload provides enhanced capabilities to the SAR mission with distress alert detection and location to 100 percent continuous global coverage and reduces location uncertainty to less than 5 km in support of 49 international partners.

    Finally, the program will host a redesigned Nuclear Detonation Detection System that has a lower overall size, weight and power requirement.

    “Along with our industry and government partners, the GPS IIIF team continues to add world-class capabilities that underpin U.S. national security needs to both our warfighters and civil users across the globe as the most utilized United States Space Force capability,” said Col. Jung Ha, GPS Space Vehicles senior materiel leader for SSC Military Communication and Positioning, Navigation and Timing.

    The GPS IIIF SV11-12 satellites were included in the original GPS IIIF contract awarded to Lockheed Martin in September 2018 to build up to 22 GPS IIIF satellites. Under that contract, SSC exercised the first production option for SV13-14 in October 2020 and second production option for SV 15-17 in October 2021.

    Space Systems Command to lead new office for security against missile threats

    New Combined Program Office to enhance U.S. ability to prevail against threats in space, including new hypersonic weapons

    Space Systems Command emblemSpace Systems Command (SSC) is leading a new tri-agency Combined Program Office (CPO) comprised of representatives from SSC, the Space Development Agency (SDA) and the Missile Defense Agency (MDA). The CPO was established on Aug. 19 to enhance the United States’ ability to deter, defend and win against competitors’ challenges in space.

    The Space Acquisition Council, established by Congress to manage space procurements across the Department of Defense, concurred on the CPO proposal, enabling the coordinated development and fielding of capabilities in the missile warning (MW), missile tracking (MT), and missile defense (MD) mission areas.

    The CPO will address growing challenges resulting from the transition of space from a peaceful domain to one that is congested, contested and competitive. Other nations now challenge access to and movement in space, and have demonstrated the capability and intent to hold U.S. and allied space assets at risk.

    “The MW/MT/MD mission is driving the U.S. Space Force’s new ‘requirements to execution’ roadmap, rapidly turning USSF Force Design into operational capabilities that will outpace and defeat very determined threats,” said U.S. Space Force Col. Brian Denaro, Space Sensing program executive officer and leader of the new CPO. “Our adversaries continue to develop missile technologies that are faster burning, dimmer and more maneuverable. This Combined Program Office, in partnership with SDA and MDA, will drive critical integration across a new resilient multilayer architecture that will warn, track and defeat these increasingly advanced and elusive missile threats.”

    Establishing this partnership among MW/MT/MD acquisition organizations will enhance the interface between requirements, operators and users, optimizing delivery of integrated and resilient sensor-to-shooter capabilities for the United States and its allies.

    “We are focused on delivering MW/MT/MD capabilities to the warfighter and the nation,” said U.S. Army Lt. Col. Alexander Rasmussen, Tranche 1 Tracking Layer program manager, SDA. “The Combined Program Office is a critical component in delivering this capability and enabling our nation to counter hypersonic and advanced missile threats. Together, SDA, MDA and SSC will ensure a synchronized end-to-end capability that sets the foundation for a continually evolving and advancing MW/MT/MD architecture.”

    “With the emerging advanced threats, space-based sensors are essential to missile defense,” said Walter Chai, director for space sensors at MDA. “The close collaboration between SDA, SSC and MDA will ensure that we are able to defeat these threats.”

    The CPO organizational structure integrates strategic decision-making across the interagency, establishing:

    1. clear roles, responsibilities, and authorities for SSC, SDA, MDA and other mission partners
    2. end-to-end system of systems accountability between requirements and weapon system delivery
    3. development and management of standards (models, open architecture, data, etc.)
    4. integration with operators, combatant commands and other weapon systems.

    Space Systems Command launches USSF-8 mission for US Space Force

    Space Systems Command, together with United Launch Alliance and other mission partners, successfully placed the fifth and sixth Northrop Grumman-built Geosynchronous Space Situational Awareness Program (GSSAP)-5/-6 satellites into orbit for the U.S. Space Force, after an on-time launch aboard an Atlas V rocket from Space Launch Complex (SLC)-41 at Cape Canaveral Space Force Station, Florida, at 2 p.m. EST (11 a.m. PST).

    “The evolving threat to our space environment requires new levels of resiliency and survivability, autonomy and automation, and unprecedented levels of integration and networking,” said Lt. Gen. Michael A. Guetlein, commander of Space Systems Command. “Today’s successful launch will enhance our capabilities in space domain awareness and our space-based space domain awareness architecture. Congratulations to the USSF-8 integrated team and all mission partners on a successful launch.”

    The GSSAP-5/-6 satellites join a constellation supporting U.S. Space Command’s space surveillance operations as a dedicated Space Surveillance Network sensor.

    GSSAP also supports the Combined Force Space Component Command by collecting space domain awareness data, allowing for more accurate tracking and characterization of manmade orbiting objects. GSSAP is led by SSC’s Special Programs directorate.

    The National Security Space Launch (NSSL) mission launched aboard ULA’s Atlas V in the “511” configuration, which was comprised of a five-meter diameter payload fairing from RUAG Space, a single Graphite Epoxy Motor (GEM)-63 solid rocket booster from Northrop Grumman, and a single RL-10 engine from Aerojet Rocketdyne on the Centaur upper stage.

    SSC’s Launch Enterprise acquired the launch service through ULA and was responsible for successfully placing the GSSAP satellites on orbit.

    The NSSL program provides assured access for the United States’s critical warfighting space assets, and this launch vehicle has reliably placed valuable assets into their intended orbits repeatedly, adding to the NSSL program’s success record of 88 consecutive launches. The program supports a full range of government mission requirements for the nation’s defense and intelligence sectors.
