Satellite transmission of orbit and clock corrections is critical for real-time positioning, navigation and timing (PNT), geoscience applications, safety and liability critical services based on Global Navigation Satellite Systems (GNSS) precise positioning. In response to such a demand, Galileo has established a High Accuracy Service (HAS) of almost global coverage for GPS and Galileo. We validate the quality of HAS corrections and investigate service performance in a variety of applications. Decimeter-level accuracy of HAS corrections leads to static and kinematic positioning with precision of a few centimeters and sub-decimeter, respectively, and timing precision of a single nanosecond. Other GNSS-derived products meet the requirements of real-time GNSS meteorology and allow for monitoring coseismic vibrations. Although other Internet correction streams offer superior results, HAS provides better performance than nominal and nearly global coverage.
