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 DATA.GOV.HK as part of the Public Sector Information (PSI). They can be acquired by means of NTRIP with the following settings.
