Description
The Network RTK Integrity Monitoring (IM) system comprises three monitoring stations located at Fanling (HKFN), Quarry Bay (HKQT), and Tate’s Cairn (TCHK). These stations continuously monitor the performance of the SatRef Network RTK service by comparing RTK-surveyed coordinates with control coordinates. The real-time data streams of these RTK-surveyed coordinates are disseminated in NMEA format via the Open Data Portal and the CSDI Portal, and can be accessed by means of NTRIP.
