Key Intelligence Findings
AIS Blackout Confirmed — 4 Events
Deliberate AIS transponder deactivation detected. Each event represents a period where ANNE JARRETT was operating outside electronic surveillance. Consistent with covert cargo transfer or evasion operations.
GPS Spoofing — 1 Position Jumps
AIS coordinates fabricated at impossible locations. Maximum jump of 4,448 km confirms the AIS transmitter is broadcasting false positions. Systematic identity concealment is in progress.
Evasion Navigation — 33 Zigzag Events
Erratic course-over-ground patterns up to 159.4° std deviation, far exceeding the 50° anomaly threshold. Pattern consistent with surveillance evasion maneuvers or anchor position AIS noise.
