SP3

Extended Standard product (SP3) files

SP3 files (SP3 a, SP3 c, SP3 d)contain detailed orbit information for the satellites in different GNSS systems. The latest version of the  Standard (SP3-d) is the evolution of the initial Standard (SP1) taking into account user feedback and the reality of more GNSS satellites in orbit. The information contained in the SP3 files consists  of precise orbit and precise clock corrections with the associated  errors for the satellites in the files. The current version allows all GNSS satellites to be included (maximum number of satellites per files was increased to a number allowing the inclusion of all GNSS satellites currently active) and also SBAS orbits.

The GSSC recognises all versions of the SP3 Standard as resource types ‘Station/Receiver Position and Velocities’ and ‘Precise GNSS orbits.
