GNSS Improvements
Page 6-11: GNSS Improvements for Offshore Applications. Currently, there are four global navigation satellite systems (GNSS) available: GPS, Glonass, Beidou and Galileo. These satellites can be used directly, but accuracy is greatly improved when using orbit, clock and UPD correction signals. Read on for a more detailed description of the recent developments and the resulting accuracy of specifically the precise point positioning (PPP) real-time kinematic (RTK) solutions. Read now.
