Monitoring and data distribution of the Galileo HAS system and user performance
Global Navigation Satellite Systems (GNSSs) provide free services such as the Galileo High Accuracy Service (HAS) to enhance navigation precision. The Joint Research Centre (JRC) developed a monitoring system for HAS corrections from Galileo signals and internet, comparing them with Multi-GNSS Experiment (MGEX) products. HAS is also exploited to compute daily position and timing solutions of IGS stations and JRC receivers. Performance is evaluated by analyzing HAS ephemeris errors and positioning accuracy considering single and dual-constellation modes. Signal-In-Space and Internet-Data-Distribution HAS corrections, their streams and the derived experimental HAS products are stored at the JRC and made available for research.
