GNSS Raw Data Streams (RTCM Format)

The Hong Kong Satellite Positioning Reference Station Network (SatRef) has been supporting high accuracy positioning applications for public since 2010. The reference stations receive real-time GNSS signals from GPS, GLONASS, GALILEO and BeiDou satellites round-the-clock. The GNSS Real-time raw data streams are then instantaneously disseminated via Open Data Portal and CSDI Portal. They can be acquired by means of NTRIP with the following settings.
