At https://tallbloke.wordpress.com/2017/03/15/auroras-affect-sat-nav-system… … This is an interesting one as aurora are produced when gas particles in the Earth's atmosphere collide with charged particles emitted from the Sun. The resulting plasma turbulence has long been thought to be the reason why global navigation satellite systems go awry. New research casts doubt on this view. Research led by Biago Forte and the department of electronic and electrical engineering at the University of Bath has discovered that predicted turbulence does not actually occur – or exist. This means something else, otherwise unknown, is affecting Sat Nav systems.
