The technologies we use range from radar, GPS, radio communications to embedded processors and IoT:

• GPS / GNSS
• Satellite communications
• Drilling
• Radar survey
• Probes
• Geophone nodes
• Surface radio network
• Base station (for probes)
• Reference station (for probe system)
• Long Range Wireless Communications
• Cameras

This simplified overview shows the probes communicating via the base station and reference station back to the server in the UK. In Iceland there are many surface stations and the base links to the internet via WiFi or GPRS.

The final version of the system shown above evolved from the addition of sensors, cameras and more IP-based networking.
