Key Intelligence Findings
Velocity Fraud — 1 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 102.2 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 36 Zigzag Events
Erratic course-over-ground patterns up to 136.4° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.

AIS SOG FRAUD
Speed anomaly events are triggered when AIS Speed Over Ground (SOG) exceeds the 30-knot detection threshold. AMERICAN CONTENDER reports speeds up to 102.2 kn — consistent with deliberate AIS SOG field manipulation to corrupt tracking algorithms.
