AIS vessel tracking where every estimate carries its evidence.

Position source
Live AIS
Every estimate is shown with the signal behind it.
Isolation
Per-organisation
Multi-tenant from the first release.

Shipment tracking built on live AIS data. The design rule throughout is that a number on the screen must be able to say where it came from.

What it actually does

  • Every arrival estimate is shown with the signal it was derived from, so an operator can tell a fix from an inference.
  • Multi-tenant from the first release, with per-organisation data isolation rather than a shared table.
Calibrate Freight LIVE

Every estimate
carries its evidence.

An operator can tell a fix from an inference, because the signal behind each arrival estimate is shown with it.
