Key Intelligence Findings
GPS Spoofing — 1 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 124 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Velocity Fraud — 18 Speed Anomaly Events
AIS SOG field manipulated to broadcast physically impossible speeds up to 99.3 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 11 Zigzag Events
Erratic course-over-ground patterns up to 116.6° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
