For format versions SP3-c and later, the satellite code Lxx indicates a low earth orbiter, in analogy to the codes Gxx for GPS and Rxx for GLONASS. The table below assigns the numbers 'xx' for the LEO satellites of interest.
For RINEX file names with LEO on-board receiver data, a four letter acronym is assigned in analogy to the IGS naming convention for terrestrial stations. The relevant LEO RINEX acronyms are also included in the table below.
For further information on data formats and conventions please refer to the following links:
The satellites that have been included at present are Low Earth Orbiters with GPS receivers, but in particular the SP3 code may be required for other LEO satellites as well. The two digit Lxx code allows for 100 LEO satellites, which seems sufficient for many years to come.If any non-GPS LEO satellite requires the assignment
of an SP3 identifier, please contact Henno.Boomkamp@esa.int.

(*) NOTE: Satellites with two or more independent
receivers use different RINEX acronyms for each system.
There will only be one SP3 code, because the orbits relate to the centre
of mass of the spacecraft.
