The base station lives permanently on the ice and links to the probes and outside world. It also takes measurements.

This was the base in Norway.

It uses a small low power computer running Linux on an ARM processor. It has a dGPS, weather station, solar and wind power, radio modem, GSM phone and radio links to talk to the probes.

Iceland Base Station

The 2008 design for Iceland was physically stronger, used gumsense/gumstix, Open Embedded linux, and GPRS for internet connection. Its power consumption is much lower (microamps) than the system made for Norway so it will have better longevity. Here you see Rob tweaking the system.
