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

• Drilling
• Radar survey
• Probes
• Geophone nodes
• Surface radio network
• Base station
• Reference station
• Long Range Wireless Communications
• Cameras
• GPS / GNSS

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