System and method for position, navigation, and timing (pnt) integrity monitoring

A system for monitoring position, navigation, and timing (PNT) integrity, comprising:

• a navigation device for receiving PNT signals from one or more satellites, wherein the navigation device generates location data based on the PNT signals, wherein the location data includes a PNT geographic location of the navigation device;
• a monitoring system for receiving the location data and metadata associated with the location data and communication of the location data to the one or more satellites and a monitoring system;
• and
• a processor operatively connected for computer communication to the navigation device and the monitoring system, wherein the processor:
• analyzes the location data and the metadata by applying one or more test criteria, wherein each test criteria utilize historical geographic location data about the navigation device and a predetermined location-based threshold;
• and
• upon determining that a result of the one or more test criteria indicates a disruption condition of the PNT signals, executes a countermeasure at the navigation device.

A non-transitory computer-readable storage medium storing instructions that, when executed by a monitoring system, cause the monitoring system to perform a process for position, navigation, and timing (PNT) integrity monitoring, the process comprising:

• receiving location data about a navigation device based on PNT signals received by the navigation device from one or more satellites, wherein the location data includes a PNT geographic location of the navigation device;
• receiving metadata associated with the location data and communication of the location data to the one or more satellites and the monitoring system;
• analyzing the location data and the metadata by applying one or more test criteria, wherein each test criteria utilize historical geographic location data about the navigation device and a predetermined location-based threshold;
• and
• upon determining that a result of the one or more test criteria indicates a disruption condition of the PNT signals, executing a countermeasure at the navigation device.
