SOLUTION CHARACTERISTICS

1. Software used :   EPOS.P.V2
2. Definition of Terrestrial Reference Frame
     Fiducial-free adjustment of all station coordinates.
     These  coordinates are then fixed in the determination of ERPs and ORBITS

3. Data used:
   - undifferenced carrier phases
   - 32 h arc solutions

5. Adjusted parameters:
   - state vector of all satellites
   - coordinate corrections
   - daily ERPs
   - tropospheric zenith path delay (8 h)
   - y-bias, solar radiation scaling factor
   - ambiguities
   - STA and SV clock parameters of each observation epoch
