Key Intelligence Findings

AIS Blackout Confirmed — 1 Event

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

GPS Spoofing — 6 Position Jumps

AIS coordinates fabricated at impossible locations. Maximum jump of 325 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.

Velocity Fraud — 12 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 — 3 Zigzag Events

Erratic course-over-ground patterns up to 96.6° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
