AIS Position Validation
Advanced RF signal-based vessel detection and tracking to validate vessels’ positions based on the unique real time coverage offered by the Spire constellation.
How does AIS position validation work?
AIS Position Validation independently calculates a vessel’s location at the time of the 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.
KPIs
- 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
- Real time information (data takes 20 minutes to process)
Accuracy
- Approx. 80% validated calculated positions lie within ~40 nautical miles from their AIS reported positions
Monitoring
- All events: 650K+ daily events
- Valid events: +-99.5%
- Invalid events: +-0.5%
Additional Benefits
- 24/7 email and customer support
