Analysis of Ionospheric Scintillations Using Gps & Navic Combined Constellation

The disturbances and irregularities in the ionosphere are the primarily recognized ramification of space weather called scintillations. Irregularities in the electron densities are the sources and roots of the Ionospheric scintillations. This article investigates the ionospheric scintillations, which is predominant in the trans-equatorial and equatorial regions.Based on data from a multi-constellation Global Navigation Satellite Systems (GNSS) receiver at the Chaitanya Bharathi Institute of Technology Hyderabad, the relationship between amplitude scintillation S4 and rate of change of total electron content (ROTI) is examined. The correlation coefficient between amplitude scintillation S4 and the rate of change of total electron content is demonstrated in this article (ROTI). The outcome validates the usefulness of the rate of change of Total electron content (ROTI) in identifying the scintillations.
