Raw signal is not intelligence. At Pacific Data Helix, we transform fragmented AIS pings and manual terminal logs into a verified truth-set for global commerce.
"We don't just aggregate data; we audit the physical movements of 100,000+ vessels to eliminate the noise of modern logistics."Explore our solutions
Every data point we serve is passed through a multi-layered verification stack. We map the digital identity of a vessel against its physical reality.
We analyze AIS transmission frequency and trajectory. If a vessel "teleports" or maintains a speed physically impossible for its class, the entry is flagged and isolated for manual review.
Satellite imagery is cross-referenced with tugboat logs and berth booking systems to confirm port analytics accuracy—ensuring "Arrival" means the ship is physically present.
Our algorithms cross-check draught readings with bill-of-lading declarations to verify load density, providing a realistic view of shipping data volume per voyage.
A systematic, strictly utilitarian approach to processing global maritime intelligence from collection to delivery.
Continuous absorption of global AIS, weather patterns, and satellite synthetic aperture radar (SAR) feeds across 9,000 global terminals.
Heuristic noise reduction. Removal of duplicate pings, static interference, and spoofed MMSI identifiers using historical fleet patterns.
Predictive modeling of Estimated Time of Arrival (ETA) based on congestion, weather, and historical seasonal throughput in Bangkok and beyond.
Final output generation. Delivery via high-speed API or structured reporting for supply chain decision-makers.
Every analytical model has constraints. At Pacific Data Helix, we are transparent about the trade-offs we manage to maintain the highest integrity in maritime trade monitoring.
In open ocean zones, signal refreshes can vary by 15-45 minutes. Our ETAs utilize Bayesian probability to account for this gap.
Old hardware occasionally transmits dual identities. Our system reconciles these using IMO number verification as the primary key.
Internal Verification Anchor
We achieve a 98.4% correlation between digital data and ground-truth terminal reports at Tier-1 ports globally.
When a vessel disables its transponder, it creates a "data shadow." We utilize Cross-Modality Reconstruction, combining historical destination patterns with current port scheduling and nearby vessel sightings. By analyzing the traffic flow around the dark zone, we can estimate exit times and headings with a high degree of confidence until the signal is restored.
Port "noise" occurs when multiple vessels wait in the same anchorage. Our system uses Geofencing with dynamic polygon adjustment. Instead of a simple radius, we map the actual terminal berths. A ship is only marked as "Arrived" when its speed drops below 0.5 knots within the specific dock polygon, cross-referenced with tugboat VHF traffic if available.
We employ a weighted multi-source consensus algorithm. Government data is given highest priority for identity, carrier APIs for scheduling, and terrestrial AIS for real-time location. If sources conflict beyond a 5% margin of error, the data point enters a "Staged" state until a third independent vector—usually satellite SAR imagery—can resolve the discrepancy.
