MARITIME DOMAIN AWARENESS • OSONWANNE GROUP LLC
WakeWatch MDA: which contacts matter, and why
WakeWatch fuses open vessel-tracking (AIS) data with sanctions, port and learned-normalcy context, runs twelve explainable anomaly detectors, and hands ranked alerts straight to the tools analysts already use.
One real day of public AIS, end to end

What it detects
Dark activity
Transponders switched off where receivers were clearly hearing other ships, vessels appearing or vanishing at sea, and go-fast profiles by small craft at night.
Meetings at sea
Ship-to-ship rendezvous and loitering offshore, scored higher when a participant went dark nearby or is sanctions-listed.
Identity and sanctions
Cloned or shared vessel IDs, impossible position jumps, invalid IMO numbers, and OFAC sanctions matches verified on IMO before name.
Built to plug in, not to replace
Watch floors already have their tools. WakeWatch is an analytics layer that feeds them in the formats they ingest today.
TAK / C2
Cursor-on-Target
Suspect-surface events for TAK Server, ATAK and WinTAK.
MAPS / COP
GeoJSON and REST
Map layers for ArcGIS, QGIS and common operating pictures, plus alert and vessel-dossier APIs.
YOUR DATA
Analyze in place
Send any AIS stream to the engine and get scored alerts back. Live mode re-scores real-time feeds every 60 seconds.
Every score shows its work
A likelihood, not a yes/no
Each alert carries a score, the signed factors behind it, and the data sources that produced it.
Suppressed with a reason
Receiver range limits, marinas, anchorages, fishing and service craft are filtered out, and every suppression stays auditable.
Learns from analysts
Confirm and dismiss feedback turns into tuning proposals, so the queue gets sharper over time.
