Abstract:

Rapid fluctuations in the amplitude and phase of L-band and E-band GNSS signals occur, when they pass through the ionosphere, because of electron density irregularities. This so-called scintillation is a consequence of electron density irregularities mainly in the E- and F-regions of the ionosphere. In this study, we have reported the presence of L-band and E-band scintillation observed using data from a newly established GNSS station (SHJ1) situated under the northern crest of the equatorial ionization anomaly (EIA) near Arabian Peninsula at 25.3oN and 55.5oE. A significant presence of weak, moderate and strong scintillation has been observed throughout the day, in general, and in the late afternoon hours (LT 1500 to 1800), in particular. However, no significant post-sunset and post-midnight scintillation has been observed.
