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