Key Intelligence Findings
GPS Spoofing — 35 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 2,530 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Velocity Fraud — 43 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 — 18 Zigzag Events
Erratic course-over-ground patterns up to 160.5° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.

Type Mismatch Assessment
AIS Declared Type
vessel_type=37 (Pleasure Craft)
Behavior Consistency
INCONSISTENT — year-round multi-port operations with 193 anomalous events are not consistent with pleasure craft use
Speed Capability
