Konsep [1 of 4]

Penggunaan network sebagai stesen-stesen rujukan berbanding single reference station membolehkan selsisih sistematik dimodelkan untuk menghapuskan selisih dalam pengukuran. Menambah jarak antara rover dengan stesen rujukan. Mengurangkan tempoh initialization. Kursus Intensif Jurukur) 29 February 2007

Konsep [2 of 4]

Dalam Sistem MyRTKnet, Pembetulan akan dihantar kepada rover melalui kaedah berikut: Virtual Reference station (VRS) VRS memerlukan komunikasi dua hala antara rover dan pusat kawalan di Ibu Pejabat JUPEM. Pembetulan akan dihantar dalam bentuk fromat RTCM dan CMR yang mana ianya boleh diterima oleh semua jenis jenama alatan GPS. Kursus Intensif Jurukur) 29 February 2007

Konsep [3 of 4]

Konsep “Virtual Reference Station” adalah dengan memperolehi network daripada stesen rujukan RTK yang dihubungkan ke pusat kawalan bagi menghantar setiap saat data melalui talian khas yang dipanggil lease line. Server di Pusat Kawalan secara berterusan mengumpul data daripada 78 receivers di seluruh malaysia dan mewujudkan pangkalaan data bagi menghasilkan pembetulan. Pangkalan data ini digunakan bagi mewujudkan Virtual Reference Station, yang terletak beberapa meter daripada kedudukan rover. Daripada stesen VRS yang diwujudkan ini pembetulan akan dilakukan dan dihantar kepada Kursus Intensif Jurukur) rover melalui NTRIP.29 February 2007
