Key Intelligence Findings
GPS Spoofing — 35 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 3,483 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Evasion Navigation — 1 Zigzag Events
Erratic course-over-ground patterns up to 149.1° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers.
