Every sensor on the water, one living picture.

Gisiott builds geographic information systems and sensor networks for waterway operations. Live traffic pictures, radar and remote sensor estates, risk modelling, and the quiet instruments that keep a coastline watched.

What we build

Instruments for people who watch the water

Four disciplines, one thread: take signals from real sensors in hard environments and turn them into a picture an operator can trust at 03:00.

Live traffic pictures

Web-native traffic displays fusing AIS, radar tracks, and electronic charts. Thousands of live targets, one-second refresh, in a browser.

AIS · RADAR · ENC · S-100 READY

Remote asset monitoring

Radars, radios, aids to navigation and shore stations instrumented end to end. Availability, drift, and fault telemetry surfaced before an operator notices anything wrong.

SNMP · TELEMETRY · ALERTING

Risk modelling

Navigational risk studies for waterways: collision and grounding frequency modelling, drift simulation, and traffic analytics built on years of archived movement data.

IWRAP · DRIFT MODELS · ANALYTICS

Operational dashboards

The systems an equipment estate runs on: fault boards, daily digests, runbooks, and monitoring dashboards that answer the phone so people don't have to.

DASHBOARDS · AUTOMATION · OPS
Selected work

Built, shipped, and on watch tonight

Systems in production for waterway and coastal operators in Southern Africa.

Traffic picture

A vessel traffic platform in the browser

Live traffic picture with watch-zone alarms, replay, electronic charting, and per-role permissions, serving operators across multiple sites from a single codebase.

SAR operations

Watch display for search and rescue

Terrestrial and satellite feeds merged into one coastal picture: thousands of offshore targets named, aged honestly, and monitored end to end, with a warm standby for failover.

Risk modelling

Quantified navigational risk for commercial ports

Collision and grounding frequency modelling from real traffic archives, delivered as defensible numbers a harbour master can act on.

Asset monitoring

A coastline of sensors, monitored as one system

Radars, radios, recorders, and servers across remote stations: instrumented, alarmed, and escalated to the right person before a fault becomes an outage.

Method

A small team with a very large pair of hands

Gisiott engineers with AI in the loop. Every system is designed, built, reviewed, and documented in an agentic workflow where the judgment is ours and the throughput is unreasonable.

FIELD FIRST

Domain before code

We operate the estates we build for. Decisions come from watchstanders, technicians, and real fault history, not from a requirements document.

AI-NATIVE

Agentic engineering

Design, implementation, adversarial review, and documentation run through coordinated AI agent workflows under engineering supervision. Weeks of work lands in days, reviewed twice.

PROVE IT

Monitored or it didn't happen

Everything we ship gets telemetry, alarms, and a place on the fault board the day it goes live. If a chart goes blank at sea, we know before the operator does.
