Perbandingan Karakteristik Aktivitas Sintilasi Ionosfer Di Atas Manado, Pontianak Dan Bandung Dari Data Penerima GPS (Characteristics Comparison of Ionospheric Scintillation Activities Over Manado, Pontianak and Bandung Based on GPS Receiver Data)

Abstract

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 Based on map of strong scintillation, it occurred more intensively over Java Sea.

Perbandingan Ketelitian Koordinat 3-D Antara Hasil Pengolahan Data GNSS Menggunakan Perangkat Lunak Hi-Target Geomatics Office dengan Trimble Business Center

“…Salah satu satelit GNSS yang paling dikenal saat ini adalah Global Positioning System (GPS). GPS dapat memberikan informasi posisi dengan ketelitian bervariasi dari beberapa millimeter (orde nol) sampai dengan puluhan meter [2]. Ketelitian posisi dari survei GPS secara umum akan bergantung pada 4 (empat) faktor, yaitu: ketelitian data yang digunakan, geometri pengamatan, strategi pengamatan yang digunakan, dan strategi pengolahan data yang diterapkan.…”
