Koordinat lokasi stasiun dari GPSGambar 4 Visualisasi alat peta digital pada server3.2 Perangkat Lunak (Software)3.2.1 Pemrograman sistem GPS di KRLProgram Arduino pada KRL dibuat untuk menerimadata dari GPS dan mengirimkan data tersebut ke stasiundan server. Pengiriman data melalui SMS denganmenggunakan teknologi GPRS. Flowchart prosespengiriman data posisi KRL dari GPS ke stasiun danserver dapat dilihat pada Gambar 5.GPS receiver akan menerima data-data dari satelitsebagai berikut:$GPRMC,075620.000,A,0622.2946,S,10649.4400,E,3.30,320.18,210911,,*1F$GPGGA,075621.000,0622.2937,S,10649.4394,E,1,06,1.8,96.9,M,2.5,M,,0000*41$GPGSA,A,3,04,10,28,08,07,05,,,,,,,3.1,1.8,2.5*3B$GPRMC,075621.000,A,0622.2937,S,10649.4394,E,3.16,327.94,210911,,*15Data-data yang berasal dari GPS tidak semuanyadigunakan.Tujuan utama pada penelitian ini hanyauntuk menentukan posisi KRL sehingga data-data yangdiambilhanya data posisi saja. Tugas Arduino adalahmengambil data-data yang diperlukan yaitu data posisikoordinat lintang (latitude), bujur (longitude), waktusekarang standar UTC (UTC time), dan kecepatan(speed over ground).Hasil koordinat posisi KRL yangberhenti disetiap stasiun dari Jakarta-Depok-Bogordapat dilihat pada Tabel 1.STARTModul GPS ONGPS Recaivermenerima data datadari satelitGPS Receiver mengirim dataposisi ke mikrokontrolerData difilter olehmikrokontroler sesuaikebutuhanData yang sudah difilterdikirim ke GSMGSM mengirimkan databerupa SMSSTOPGambar 5.Flowchat sistem GPS pada KRLISBN: 978-602-97832-0-9NO.
