Our experiment has been selected to run on the ISS in the context of the Astro Pi Proxima Mission. Our code was run on the ISS by ESA astronaut Thomas Pesquet with the help of mission control.
The UltimaSpace experiment was coded in python. It used the Pyephem ephemeris module to calculate the position of the ISS and logged it alongside the magenetometer readings.
Our method of visualization uses a Geochart to show the weakest magnetic points and the magnetic field strength around them. The points can be clicked to see a magnified view.
