Key Intelligence Findings
AIS Blackout Confirmed — 1 Event
Deliberate AIS transponder deactivation detected. Each event represents a period where CGC WILLIAM HART was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
GPS Spoofing — 33 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 4,569 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 67.1 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.
Evasion Navigation — 6 Zigzag Events
Erratic course-over-ground patterns up to 179.0° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
