## Governing question

When should navigation information be trusted, qualified, or rejected?

## Direct answer

Navigation integrity concerns whether navigation information is trustworthy for a stated operation and whether the user receives a timely indication when it should not be used. The required error bounds, alerting behavior, monitoring, and response depend on the application; integrity is distinct from accuracy and availability.

## Why it matters

Incorrect navigation information can be more hazardous than unavailable information because a system may continue acting on a plausible but misleading result. Buyers must therefore specify acceptable risk, monitoring, alerting, and operational response for the intended use.

## Definition

The degree to which navigation information and its associated status can be relied upon for a stated use, including the ability to identify when that reliance may no longer be appropriate.


## Capability relationships

Navigation Integrity is closest to Assured PNT. Integrity supplies evidence about the correctness and status of navigation information; assurance determines whether the combined evidence is sufficient for mission reliance.

## Standards and authority context

The GPS Standard Positioning Service Performance Standard defines integrity in terms of trust in positioning or timing information and timely alerts, while FAA guidance shows how integrity monitoring affects operational use. LJP does not generalize aviation thresholds to other sectors.

## Package

Navigation Integrity is one peer Capability Namespace within Sovereign PNT & Resilient Timing at https://sovereignpnt.com/.

## Credibility boundary

This namespace does not define integrity algorithms, alert limits, monitoring implementations, certification criteria, safety requirements, or operational thresholds.
