AIS Position Validation Software

Using additional RF data through doppler frequency shift and associated accurate timing data collected at the time of receipt of transmitted AIS messages, AIS Position Validation independently calculates a vessel’s location at the time of AIS transmission (even if AIS messages do not include valid GPS data).

This can be compared to the reported position contained within the AIS messages received from a vessel.

• Continuous global coverage
• Calculated position and timestamp in any given 24 hour period since October 2022
• Distance between reported and calculated position
• Range of event types, each with timestamp and timestamp
• Real time information (data takes 20 mins to process)

• Complementary to other dark vessel detection methods
• Support AIS spoofing detection
• No need for human validation
• Data lookback since October 2022
• Contributes to data integrity
• AIS Position Accuracy: Approx. 80% validated calculated positions lie within ~40 nm from their AIS reported positions
• Monitoring AIS Positions:

• • All events: 650K+ daily events
  • Valid events: +-99.5%
  • Invalid events: +-0.5%
  • Out of footprint events: +-0.04%
