A system for measuring the scintillation index based on the results of monitoring of small-scale fluctuations in the total electron content of the ionosphere

It is possible to determine the ionospheric scintillation index with a modified NovAtel GPStation-6 dual-frequency GPS/GLONASS receiver by measuring small-scale fluctuations in the total electron content of the ionosphere and calculating their standard deviation. Based on the analysis of the shortcomings of the GPStation-6 receiver, the algorithm for monitoring of small-scale fluctuations of the total electron content based on digital filtering is substantiated. Experimental results of measurement of small-scale fluctuations of the ionospheric total electron content and results of estimation of their root-mean-square deviation and ionospheric scintillation index are presented.
