Eleven years marks only one iteration of the cycle of solar activity, but it represents several generations of GNSS receiver design. So, as the next high point of sunspots arrives in 2013 much of the installed base of GPS equipment will have been untested in the environment of intense ionospheric scintillation that accompanies the solar maximum. Scientists at Cornell University have developed a model of this scintillation to help evaluate the performance of GNSS user equipment in the face of potential disruption.
