Abstract

Global Positioning System (GPS) merupakan salah satu dari teknologi Global Navigational Satelite System (GNSS), yang digunakan untuk menentukan posisi yang dapat dimanfaatkan untuk kegiatan bernavigasi, pemantauan struktur bangunan, landslide, gempa bumi maupun tsunami. Penentuan posisi secara aboslut atau Precise Point Positioning saat ini berkembang dengan cepat seiring dengan meningkatnya akurasi posisi yang dihasilkan. PPP merupakan alternatif penentuan posisi dengan menggunakan metode absolut yang dapat mecapai akurasi dalam skala sentimeter maupun desimeter atau bahkan hingga milimeter. Pada penelitian ini menggunakan data pengamatan dual frekuensi dari CORS CBAL, CPAL, CAMP, CMLI, CRAU yang kemudian diolah menggunakan software GoGPS metode PPP dengan menggunakan koreksi ionosfer orde 1. Hasil yang didapatkan dari penelitian ini yaitu pada stasiun CORS CAMP, CBAL, CPAL, CRAU dan CMLI diperoleh hasil standar deviasi berkisar antara dm hingga cm. Waktu konvergensi yang diperlukan mencapai 3,3jam untuk mendapatkan solusi dengan level mm. Nilai standar deviasi yang paling kecil terdapat pada hasil penentuan posisi stasiun CORS CAMP dan CBAL.
