POSEIDON-OS

Free, open-source maritime port intelligence platform.

Fuses ESA Sentinel-2 satellite imagery with public AIS transponder data to monitor hostile naval ports in near-real-time.

Target ports

• Sevastopol Naval Base
• Novorossiysk Port
• Kerch Strait

Capabilities

• YOLOv8 ship detection on Sentinel-2 optical imagery (10m resolution)
• AIS fusion — cross-reference satellite detections vs transponder data
• Dark vessel identification — ships visible from satellite but NOT broadcasting AIS
• 14-day activity baseline + anomaly detection
• REST API — 7 endpoints, JSON intelligence reports

Sample output

{
  "port": "Sevastopol Naval Base",
  "threat_level": "HIGH",
  "vessel_count": { "satellite": 6, "ais": 5, "dark": 1 },
  "alerts": [
    "2 landing ships detected — potential amphibious activity",
    "1 dark vessel — possible military/covert ops"
  ]
}
