Key Intelligence Findings

GPS Spoofing — 2 Position Jumps

AIS coordinates fabricated at impossible locations. Maximum jump of 5,523 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.

Velocity Fraud — 2 Speed Anomaly Events

AIS SOG field manipulated to broadcast physically impossible speeds up to 35.1 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.

Evasion Navigation — 5 Zigzag Events

Erratic course-over-ground patterns up to 138.9° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
