Executive Order 13905: Strengthening National Resilience Through Responsible Use of Positioning, Navigation, and Timing Services
President: Donald J. Trump
Directed agencies and critical-infrastructure partners to identify and manage risks from disrupted or manipulated positioning, navigation and timing signals, including GPS-dependent services.
Status: In effect. Is Executive Order 13905 still in effect? Yes. Executive Order 13905 remains in effect. See Federal Register record.
What does Executive Order 13905 do?
NIST published its foundational PNT cybersecurity profile in February 2021 as a response to the order.
Evidence review, September 23, 2026: NIST published a foundational positioning, navigation and timing cybersecurity profile in response to the policy work.
Before and after
Before the order
Critical infrastructure can depend on GPS and other positioning, navigation and timing services whose disruption or manipulation can propagate into dependent systems.
After the order
NIST published its foundational PNT cybersecurity profile in February 2021 as a response to the order.
The NIST profile helps organizations identify and manage PNT risks; publication is not proof that infrastructure operators adopted it or that disruptions ceased.
Who had to do what
| Agency / official | What the signed order directed | Deadline / timing |
|---|---|---|
| Secretary of Commerce | Develop and publish PNT profiles with sector agencies/private-sector consultation; provide a GNSS-independent UTC source. | Profiles within 1 year; review every 2 years; UTC source within 180 days |
| Secretary of Defense | Use PNT profiles when updating the Federal Radionavigation Plan. | When updating the plan |
| Secretary of Transportation | Use profiles in radionavigation updates; develop a critical-infrastructure PNT pilot plan and complete it. | Pilot plan within 180 days; completion within 1 year of planning |
| Secretary of Energy | Develop and complete a critical-infrastructure PNT pilot. | Plan within 180 days; completion within 1 year of planning |
| Secretary of Homeland Security | Coordinate vulnerability testing, contract language, and adoption reports; use profiles in radionavigation updates; develop/complete a PNT pilot. | Testing plan within 1 year; pilot plan 180 days/completion 1 year later |
| Sector-Specific Agency heads and other applicable agency heads | Coordinate profile/testing work; develop/update procurement requirements through DHS; report adoption through DHS to national-security adviser and OSTP. | Contract language 90 days after profiles; adoption report 1 year after profiles, and biennially |
| Federal Acquisition Regulatory Council | Consult agencies and incorporate developed requirements into contracts where lawful/practicable. | Within 180 days after procurement-requirement work |
| OSTP Director | Coordinate national R&D/pilot plan for robust non-GNSS PNT and integrating multiple services. | Within 1 year; update every 4 years or as appropriate |
