The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Asked vs spent: the PB2024 book requested $121.8M for FY2024; the PB2026 book reported $101.4M as actual total obligation authority — $20.4M below the request. 101.4 − 121.8 = -20.4 USD millions — the compact figures above are rounded for reading.

Description
Description — GPS III Space Segment
The Global Positioning System (GPS) is a space-based navigation system that fills validated Joint Service requirements for worldwide, accurate, common grid three-dimensional positioning/navigation for military aircraft, ships, and ground personnel. The consistent accuracy, unaffected by location or weather and available in real time, significantly improves effectiveness of reconnaissance, weapons delivery, mine countermeasures and rapid deployment for all services. GPS must comply with Title 10 United States Code (USC) Sec. 2281, which requires that the Secretary of Defense ensures the continued sustainment and operation of GPS for military and civilian purposes, and 51 USC Sec. 50112, which requires that GPS complies with certain standards and facilitates international cooperation. The system is composed of three programs: User Equipment (funded under Program Element (PE) 1203164F, 1203164SF), Space (funded under PE 1203165F, 1203265F, 1203265SF, 1203269F, and 1203269SF), and a Control Network (funded under PE 1206423F, 1206423SF and 1203165F). The satellites broadcast high accuracy data using precisely synchronized signals that are received and processed by user equipment installed in military platforms. The user equipment computes the platform position and velocity and provides steering vectors to target locations or navigation waypoints. The control segment provides daily updates to the navigation messages broadcast from the satellites to maintain system precision in three dimensions to 16 meters (spherical error probable) worldwide. Additionally, GPS supports the United States Nuclear Detonation Detection System mission and provides strategic and tactical support to the following Department of Defense missions: Joint Operations by providing capabilities for Positioning, Navigation, and Timing (PNT); Command, Control, Communications, and Intelligence; Special Operations; Military Operations in Urban Terrain; Defense-Wide Mission Support; Air Mobility; and Space Launch Orbital Support. GPS III is the next generation of Space Vehicles (SV) supporting the GPS constellation. GPS III SVs deliver significant enhancements, including a new international civil (L1C) Galileo-compatible signal, and enhanced anti-jam power. GPS III SVs 08-10 are in the Production and Deployment Phase. The Air Force GPS directorate received USD(AT&L) approval to purchase GPS III SVs 09-10 at the December 2014 Defense Acquisition Board in order to sustain the constellation while competitive options were pursued. The GPS III SVs 09-10 purchases are on the current Lockheed Martin contract as technical equivalents of SVs 01-08. SV 09 is funded with FY 2014 Missile Procurement, Air Force (MPAF) advance procurement and FY 2015 MPAF regular procurement. SV 10 is funded with FY 2015 MPAF advance procurement, and FY 2016 Space Procurement, AF regular procurement. SV 01 and SV 02 were successfully launched in December 2018 and August 2019, respectively. SV 01 was operationally accepted in January 2020 and SV 02 was operationally accepted in March 2020. SV 03 was successfully launched in June 2020 and operationally accepted in July 2020. SV 04 was successfully launched in November 2020 and operationally accepted in December 2020. SV 05 was successfully launched and operationally accepted in June 2021. SV 06 was successfully launched and operationally accepted in January 2023. SV 07 was successfully launched and operationally accepted in January 2025. SV 08 achieved Available for Launch (AFL) in June 2021 and has a projected Initial Launch Capability (ILC) in Q3, FY 2025. SV 09 achieved AFL in August of 2022 and SV 10 achieved AFL in December 2022. FY26 funding will support SV 07 (launched December 2024), SV 08 (launched May 2025), and SV09 launches in FY 2025, and SV10 projected launch in FY 2026. Funding for this exhibit is contained in PE 1203265SF.
Justification
Justification — GPS III Space Segment
FY 2026 funding will procure independent technical and integration support critical to managing SVs 07-10. Funding supports SV07-10 Operational 365 Days On-Orbit Incentive Milestones and SV10 Launch and Declared Operational On-Orbit Incentive Milestones. Funding also supports SV 10 crosslinks support, mission assurance activities, launch preparation events, and planned Initial Launch Capability in FY 2026. FY 2026 funding will allow the program to rapidly respond to implement system resiliency and situational awareness necessary to operate through the contested space domain. Activities may include, but are not limited to, program office support, studies, technical analysis, and activities that may leverage commercial, U.S. Government partnership, and international opportunities to respond to existing and emerging adversarial threats with speed and agility, etc.

Follow the dollar
Appropriation → program element → top high-confidence awards → recipient families → congressional districts.
Follow-the-dollar covers 312 of 1,938 programs — only high-confidence budget→award links are shown. why coverage is partial? →
The diagram illustrates the cited table below — amounts shown in the diagram are transaction sums per award (no citation chips); the per-district obligations in the table cite USAspending queries.
Related awards
Award linkage is shown for 32 of 200 profiled companies — high- and medium-confidence USAspending matches, each row labeled; medium is the weaker evidence. why partial award coverage? →
Rows marked medium rest on evidence weaker than a program-level match, and of more than one kind. An account-based row, where the award drew from the same appropriation account as this program, is an association, not evidence that this program paid for the contract. Where the evidence is instead an FPDS acquisition-program tag or a subaward description, the program is established but which of its budget lines paid is not. An announcement link a recorded review did not leave standing is medium too. Only high rows rest on the contract naming this program with a recorded review upholding it and no recorded rejection or refutation applying.
| Recipient | PIID | Confidence |
|---|---|---|
| LOCKHEED MARTIN CORP | FA880708C0010 | high |
| ENGILITY SERVICES, LLC | FA880715C0005 | medium |
Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
Lobbying mentions
