Analysis occurrence of equatorial and low latitude ionospheric scintillations over Indonesia

Abstract

Strong scintillations over Pontianak (0. ) was compared to find out the spatial distribution of ionospheric scintillation. Data was obtained from GISTM GSV4004B. Percentage occurrence of strong scintillation was counted at each observation station. Result showed the occurrence of scintillation over Pontianak was higher than Bandung, but on March and on September, the occurrence of scintillation over Bandung higher than in Pontianak.
