§1 — Definition
Assured PNT
The disciplined evaluation of whether positioning, navigation, and timing information is sufficiently dependable for a stated mission, operating condition, and decision context.
§2 — Relationships
Closest related capability
Difference
Relationship
Closest comparison and adjacent concepts.
Assured PNT is closest to Navigation Integrity because both concern justified reliance. Integrity focuses on the trustworthiness and alerting status of navigation information; assurance combines that evidence with mission requirements, operating conditions, cybersecurity, governance, and other controls.
What separates them
Assured PNT is the broader mission-confidence judgment; Navigation Integrity addresses whether navigation information and its status support continued use or require qualification or rejection.
How they work together
Integrity evidence can support assurance, but assurance also considers mission requirements, operating conditions, resilience, cybersecurity, governance, and other evidence.

§3 — Standards and AuthorityPrimary authority ↗ Primary authority ↗
Where the terminology comes from.
CISA acquisition guidance connects PNT resilience requirements to operational needs, threats, recovery, and source behavior, while NIST provides a broader risk-management framework for responsible PNT use. LJP uses Assured PNT in a cross-sector, implementation-neutral sense and does not claim certification authority.

§4 — Evaluation
Apply the distinction to the decision at hand.
The namespace helps technical, safety, acquisition, and governance teams ask what evidence and decision criteria are appropriate before relying on PNT for a particular use.
§5 — LJP Foundation
How this capability fits the package.
Assured PNT focuses on confidence, evidence, governance, and mission fitness. It distinguishes a justified assurance judgment from simple source availability and from claims that one architecture is universally trustworthy.
Assurance connects mission requirements to evidence and confidence while resilience addresses continuity and integrity addresses information trustworthiness.
