Ionospheric scintillation, which occurred after sunset, could cause satellite signal degradation. Ionosphere over vast Indonesian territory need to be known its perturbations. This research aimed to analyze longitudinal occurrence of ionospheric scintillation from three GPS receiver over Indonesian territory on April 10, 2013. Data was obtained from the GPS receiver at the Kototabang (-0.20â°S; 100.32â°E), Pontianak (-0.03â°S; 109.33â°E) and Manado station (1.48â°N; 124.85â°E) on April 10, 2013. This paper presents the preliminary result of ionospheric scintillation variation longitudinally over Indonesia. The results showed that the strong scintillation (S4 > 0.5) first detected in Manado station, one hour later detected in Pontianak and 30 minute later detected in Kototabang in duration of approximately 1.5 – 3 hours. The strong scintillation occurred at 20:00 to 21:00 local time. The most intense of ionospheric scintillation was around at 100â° E geographic longitude in duration up to 4 hours.
