Image: CoPilot AI What’s new: The UK government has contracted for development of a Resilient PNT Standard. The entity doing the work is a spin off of the Royal Institute of Navigation. Why it’s important: Standards are essential because words mean things. It is very difficult turning words like “resilience” into hardware and software. Agreements on definitions are standards against which systems and equipments can be measured. They are absolutely essential for communications, compliance, compatibility, interoperability, certification, etc. What else to know: The project scope and definition is admittedly a bit vague at this point. RIN CEO Ramsey Faragher says in a LinkedIn post “The first job of our standards committee will be to agree on its scope and aims, but my inception point for the standard is that it will concentrate on safety critical applications within all Critical National Infrastructure, and will likely focus on the correct use of […]
Analysis Summary
# Regulation/Compliance: UK Resilient PNT Standard
## Overview
This initiative involves the development of the United Kingdom’s first formal national standards for Resilient Positioning, Navigation, and Timing (PNT). The standard aims to create uniform definitions and technical benchmarks for "resilience," moving beyond vague terminology to actionable hardware and software requirements. It serves as a foundational framework for ensuring that Critical National Infrastructure (CNI) can maintain PNT capabilities in the face of interference, jamming, or system failures.
## Key Details
- **Issuing Authority:** Department for Science, Innovation & Technology (DSIT); Developed by RIN Enterprise Ltd (Royal Institute of Navigation spin-off).
- **Effective Date:** Development began September 2026; Publication expected post-2029.
- **Jurisdiction:** United Kingdom.
- **Status:** Proposed / Under Development (Contracted).
## Requirements
### Mandatory Requirements
*Note: Specific mandatory controls are currently being defined by the standards committee.*
1. **Safety-Critical Interoperability:** Systems within CNI must meet defined resilience benchmarks to ensure compatibility and certification.
2. **Standardized Definitions:** Adoption of formal, technical definitions for "Resilience" as applied to PNT hardware and software.
### Recommended Practices
1. **Radio-Based Source Diversification:** Early focus suggests organizations should prioritize the correct use and integration of diverse radio-based PNT sources.
2. **Dependency Mapping:** Organizations should identify failure chains where safety-critical applications rely on GNSS/GPS signals.
## Affected Organizations
- **Industries:** All Critical National Infrastructure (CNI) sectors, including Telecommunications, Energy, Transport, and Emergency Services.
- **Organization Size:** Not specified, but likely to impact any entity managing "safety-critical" applications.
- **Geographic Scope:** United Kingdom.
## Compliance Timeline
- **25 September 2026:** Procurement notice published and contract awarded.
- **FY 2026/27:** Project inception and scoping phase by the RIN standards committee.
- **31 December 2027:** Expiration/expected alignment point for related US IEEE P1952 standards.
- **30 July 2029:** Scheduled end of the UK development project and publication of the formal standard.
## Implementation Guidance
### Assessment Phase
- **Audit Dependencies:** Identify every system within the organization that relies on PNT (GPS/GNSS) for timing or location.
- **Gap Analysis:** Evaluate current equipment against emerging definitions of "resilience" (e.g., ability to detect and mitigate spoofing).
### Implementation Phase
- **Hardware Updates:** Prepare for future requirements to integrate resilient PNT user equipment (RPUE).
- **Redundancy Integration:** Incorporate non-GNSS PNT sources (e.g., eLoran, LEO PNT) as per the standard’s focus on radio-based sources.
### Validation Phase
- **Certification:** Once published, equipment must be measured against the new standards to achieve UK compliance certification.
## Technical Requirements
- **Resilience Benchmarks:** Technical controls for hardware/software to ensure continued operation during signal degradation.
- **Signal Integrity:** Measures to verify the authenticity of radio-based PNT sources to prevent spoofing.
## Penalties & Enforcement
- **Fines:** TBD (Standard is currently in the development phase under the Procurement Act 2023).
- **Other Consequences:** Potential loss of certification for safety-critical operations; increased insurance premiums for non-compliant infrastructure.
- **Enforcement:** Likely to be enforced through UK CNI regulatory bodies and DSIT oversight.
## Related Standards
- **IEEE P1952:** The U.S. standard for Resilient PNT User Equipment (expected 2027). The UK standard will likely seek compatibility with this international effort.
- **NIST PNT Profile:** Foundational cybersecurity framework for PNT services.

## Practical Recommendations
- **Monitor Committee Output:** Follow the Royal Institute of Navigation (RIN) updates as they define the technical scope over the next 12 months.
- **Advocacy:** Use the current "vague" phase to engage with government leaders regarding the specific dependencies of your industry sector.
- **Future-Proofing:** When procuring new PNT-dependent hardware, inquire about the manufacturer’s alignment with IEEE P1952 or the emerging UK Resilient PNT Standard.
