Key Intelligence Findings

AIS Blackout Confirmed — 1 Event

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

Velocity Fraud — 11 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 — 9 Zigzag Events

Erratic course-over-ground patterns up to 152.0° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
