Key Intelligence Findings

AIS Blackout Confirmed — 4 Events

Deliberate AIS transponder deactivation detected. Each event represents a period where LESNEY BYRD was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.

GPS Spoofing — 1 Position Jumps

AIS coordinates fabricated at impossible locations. Maximum jump of 806 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 102.2 knots. Systematic falsification of movement data to corrupt automated tracking algorithms.

Evasion Navigation — 58 Zigzag Events

Erratic course-over-ground patterns up to 121.6° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
