Their measurements not only confirm Galileo performance at extremely high latitudes, but also offer knowledge of space weather events overhead. In particular they offer insights into the ionosphere – the electrically active upper layer of Earth’s atmosphere – above the southern continent, and the performance of Galileo software to correct ionospheric interference.
