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:

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