Key Intelligence Findings
AIS Blackout Confirmed — 20 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where DARRELL L. 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 1,551 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 — 15 Zigzag Events
Erratic course-over-ground patterns up to 146.4° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
