PROCESSING STRATEGY:
-------------------------------------------------------------------------------
- The analysis was done by fixing the GPS orbits and Earth rotation parameters
to the CODE final GPS solution.
- The orbital parameters for the GLONASS satellites were estimated using double
difference phase observations (including double differences between GLONASS
and GPS satellites). Six initial conditions and nine radiation pressure para-
meters per satellite were determined. No pseudo-stochastic pulses have been
introduced up to now.
- So far only receivers providing dual frequency GPS and GLONASS or dual fre-
quency GLONASS measurements were included in the solution.
- The daily orbit results stem from the middle day of a 5-day arc.
- The satellite clock values included in the precise orbit files are broadcast
clock values for the GLONASS satellites (no improvement done so far) and
precise CODE estimates for the GPS satellites.
- The following sites are constrained to their ITRF97 coordinates:
- KR0G 10422M001 (Kiruna, Sweden)
- METZ 10503M005 (Metsahovi, Finland)
- OS0G 10402M004 (Onsala, Sweden)
- YARR 50107M006 (Yaragadee, Australia)
- ZIMZ 14001M005 (Zimmerwald, Switzerland)

Remark: These RMS values may be too optimistic, because we fit the middle days
of 5-day arcs with a 7-day arc.
