Tracking assets.

Following an asset

Search any vessel or aircraft by name or identifier and select Follow. Followed assets appear in your tracking list, their positions update continuously from AIS and ADS-B feeds, and their full movement history becomes available on demand.

Building geofences

A geofence is a boundary that watches for asset behaviour rather than imagery change. Draw one around a port, a strait or an exclusion zone, then create alerts for the behaviours you care about:

• Entry: an asset crosses into the zone
• Exit: an asset leaves the zone
• Loitering: an asset stays inside the zone longer than a time you set
• Meeting: two followed assets come unusually close, useful for spotting transfers at sea

When vessels go dark

Ships avoiding attention sometimes switch off their transponders. GEOSY flags gaps in a followed vessel's track and, where satellite imagery covers the area, helps you check what was actually present during the silence. A gap is not proof of wrongdoing, but it is always worth a look.

Reading a movement history

Open any followed asset to see its track over your chosen period, with stops, speed changes and zone events marked. Drag across the track to replay it. Every history can be pinned into a case or exported through the API.
