Key Intelligence Findings
GPS Spoofing — 1 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 135 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Evasion Navigation — 35 Zigzag Events
Erratic course-over-ground patterns up to 102.8° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
