They are located at Fanling (HKFN), Quarry Bay (HKQT) and Tate's Cairn (TCHK). These three stations are continuously operating and receiving Network RTK correctional signals from SatRef, the difference between the RTK surveyed coordinates and control coordinates are instantaneously plotted in charts.
