Which stretch of water does your station cover?

Share a coverage screenshot and tell us what your @MastNode is watching.

The GNSS chip in every @MastNode was put there to timestamp ship messages.

With @onocoyRTK, it can do a second job: supplying GNSS reference data for centimetre-level positioning.

For the best dual-mining experience, get the MastNode + RTK bundle from mastnode.com.

A year ago, we won Best New Startup 2025 at the AIS Summit in Hamburg.

Since then, the network has grown from 300 to 850+ nodes.

A look back at where we were then. 👇

What happens after you install a @MastNode?

It starts receiving AIS signals from nearby ships and contributing them to MastChain.

Operators can track their station's reception, coverage, and rewards directly in the dashboard.

Who needs maritime AIS data?

→ Ports tracking vessel movements
→ Logistics companies planning arrivals
→ Researchers studying shipping activity
→ Maritime authorities monitoring traffic

Every well-placed @MastNode helps improve coverage and data quality across the network.
