NOTIFICATION:
Users of CODE GNSS orbit products (final, rapid, or ultra-rapid) are
advised that corresponding SP3c files may include orbital positions
(and clock offsets) for repositioned GPS satellites. This concerns
particularly
- PRN 22 on 05-Jan-2004 06:54:33 GPST
- PRN 02 on 06-Jan-2004 04:25:29 GPST
The information is validated through high consistency between orbits
and clocks.
Estimated time (mean epoch of event) and components of velocity change
will be given in our IGS analysis summary files. Repositioning events
are marked with a maneuver flag in the SP3c files.
The CODE AC Team
