update on our next generation ice tracker

Thanks to a lot of work by students over the past year we are on track to producing our new u-blox based trackers for Iceland this summer

Our new choice of microcontroller board running Circuitpython – it is connected to the GPS, its radio and if it is a base station – an off-site internet connection board. The processor is a 120MHz ARM Cortex-M4F.
The dGPS board by Sparkfun allows us to take measurements within about 30-50s, accurate to about 2cm. They use 1/10th of the power of our previous units so our batteries can be smaller.
This is the SWARM sat-coms board by Sparkfun – allowing data communications to the web from anywhere on the planet! We will test this from a base station to shjow that the system can work anywhere and send data back to researchers daily.
