REMARKS: (1) Again less than 50% of data for satellite PRN13
for all days during this week. Results are not
included for the whole week.
(2) PRN09 was excluded from processing due to modelling
problems on days 336,337.
(3) PRN25 was not tracked on day 336.
CLOCK ESTIMATION: ALGO was used as time reference

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 (4 h)
- y-bias, solar radiation scaling factor
- ambiguities
- STA and SV clock parameters of each observation epoch
