Galileo Navigation Data

The navigation data contain all the parameters that enable the user to position. They are stored on board each satellite with a validity duration and broadcast worldwide by all the satellites of the Galileo constellation. These are the 4 types of data needed to perform positioning:

  • Ephemeris which are needed to indicate the position of the satellite to the user receiver
  • Time and clock correction parameters which are needed to compute pseudo-range
  • Service parameters which are needed to identify the set of navigation data, satellites, and indicators of the signal health
  • Almanac which are needed to indicate the position of all the satellites in the constellation with a reduced accuracy
