REMARKS: (1) on day 242 manoeuver of satellite PRN02
(2) AS for satellites PRN17 and PRN24 on day 246,
for satellite PRN17 on day 247
(3) no data for following satellites (no orbit improvement):
on day 245 for satellite PRN27 (from 6h day 245 till 3h day 246)
on day 246 for satellite PRN03 (from 20h day 245 until 2h day 247)
on day 247 for satellite PRN29 (starting from 11h day 246)
(4) bad overlap for satellite PRN12 on day 245 due to the lack of
observations on days 244, 245
(no data from 15h day 244 untill 8h day 245)
(5) modelling problems on day 244 with satellite PRN16
(6) possible manoeuver of satellite PRN27 on day 245

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
