A condition in which the device or system contains no compromised internal components or data fields (e.g., data stored to memory) and from which the device or system can recognize and process valid input signals and output valid PNT solutions. An initial pre-deployment configuration is a basic example. The accuracy of the immediate PNT solution is not specified in this definition, as it will depend on the specifics of the device or system’s performance and the degradation allowed by different resilience levels.
