| Abstraksi | : | The characteristics of ionospheric scintillation activity in certain region need to be known since its occurrence can degrade satellite signal quality of global satellite navigation system (GNSS) and also satellite communication especially works at L-band frequency. The occurrence of ionospheric scintillation varies with location. Therefore, this paper aims to determine comparative characteristics of ionospheric scintillation activity over Manado, Pontianak and Bandung from amplitude scintillation index S4 data derived from GPS receiver. The data were obtained from the GPS Ionospheric Scintillation and TEe Monitor (GISTM) at Manado station (1.48 N; 124.85 E, geomagnetic latitude 7.7 S), at Pontianak station (0.03 S; 109.33 E, geomagnetic latitude 9.7 S) and at Bandung (-6.90 S; 107.6 E, geomagnetic latitude 16.54 S) on July 2014 to June 2015. The data were classified into three categories: quiet, moderate and strong, based on s4 index. Then we calculated number of monthly scintillation occurrence from each observation station and mapping of S4 index over Manado, Pontianak and Bandung. The results showed that the percentage of strong scintillation (S4>0.5) above Manado was always lower than the other stations. Strong scintillation detected at one stations might not be detected at other stations. For very intense scintillation event, its occurrence could be detected by all observation stations but vary in duration. Duration of strong scintillation over Bandung was the longest (up to 4 hours) compared to Pontianak (less than 2 hours) and Manado (less than 1 hour). Based on map of strong scintillation, it occurred more intensively over Java Sea. |
