Key Intelligence Findings
GPS Spoofing — 8 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 3,651 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Velocity Fraud — 1 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 81.0 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 34 Zigzag Events
Erratic course-over-ground patterns up to 193.6° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
