AMSAS / Passifera

Maritime AIfused atwatch speed.

Hubble Stack AMSAS is an AI-enabled Maritime Security Analytics System designed as a non-intrusive decision-support layer over the existing Coastal Surveillance Network. It turns fragmented sensor feeds into one risk-ranked operational picture.

The mission

You cannot intercept what the system cannot correlate.

Dark vessel candidates

Radar-only contacts, AIS gaps, missing identity, and track continuity become review-ready evidence instead of scattered operator clues.

Spoofing and mismatch logic

Duplicate MMSI, invalid identity, EO class mismatch, route conflict, and registry inconsistencies are surfaced with confidence.

Suspicious behavior patterns

Loitering, geofence entry, route deviation, unexpected meetings, and abnormal movement are ranked as Vessels of Interest.

VOI ranked alert
HIGH / PASSIFERA-82

Explainable risk, not black-box alarm noise.

AMSAS combines deterministic rules, geospatial logic, statistical anomaly detection, and ML models. The system prioritises evidence and keeps authorised watchkeepers in control.

Fusion layer

Multi-sensor fusion

Associates radar, AIS, EO, VHF, PANS, weather, and external intelligence into one maritime entity.

Auditable

Evidence-first alerts

Every alert carries track history, geofence events, transcripts, documents, EO frames, or registry matches.

Operator aid

RAG MDA assistant

Searches vessel history, PANS records, VHF transcripts, reports, and intelligence records with cited context.

Human led

Advisory-mode AI

AI recommends and explains while final watchkeeping decisions remain under authorised human control.

Pilot path

From proposal to controlled operational validation.

010-5 months

Foundation and offline prototype

Acquire sample data, define schemas, build ingestion, implement baseline fusion, geofence logic, risk scoring, and an initial dashboard.

024-9 months

AI modules and validation

Add anomaly detection, behavior analytics, EO classification, PANS extraction, VHF ASR/NLP, error analysis, and false-alert tuning.

038-14 months

Controlled live deployment

Integrate selected live feeds in advisory mode, compare outputs with watchkeeper observations, and build model governance.

0414-18 months

ICG collaboration and scale-out

Run UAT, refine operational workflows, harden security, prepare V&V evidence, training material, and deployment guidance.

Validation metrics

Built to be measured in the pilot, not merely admired in a deck.

The demonstration target is a pilot-ready maritime decision-support system with measurable association accuracy, false-alert reduction, latency, extraction quality, and operator workload impact.

Prototype scenario

A clean narrative for demo, validation, and stakeholder review.

  1. Simulated AIS and radar feeds enter the ingestion layer.
  2. A radar contact continues without an AIS match.
  3. Another vessel enters a restricted geofence and begins loitering.
  4. EO classification conflicts with the AIS-declared vessel type.
  5. PANS data shows a missing or mismatched pre-arrival record.
  6. VHF transcripts reveal suspicious meeting-related communication.
  7. The risk engine ranks the vessel HIGH with evidence attached.
  8. The MDA assistant summarises why a watchkeeper should investigate.

Secure by design

Deploy as an on-prem or private-cloud intelligence layer.

AMSAS is shaped for coastal surveillance environments where audit, explainability, role-based access, model traceability, and operator trust matter as much as detection speed.
