UNCLASSIFIED/UNLIMITED UNCLASSIFIED/UNLIMITED An Investigation into the Relationship between Ionospheric
Irregularities in the ionospheric electron density can cause a phenomenon known as scintillation, in which the phase and amplitude of transiting radio signals fluctuate rapidly. Scintillation can have an adverse effect on Global Navigation Satellite Systems (GNSS) signals as they pass from a satelli...
