SOLUTION CHARACTERISTICS
- Software used : EPOS.P.V2
- Data used:
- undifferenced carrier phases
- 1 day arc solutions
- the following observations are used:
- stations with GPS and GLONASS dual frequency measurements: all
observations are used
- stations with GPS single frequency and GLONASS dual frequency
measurements: only GLONASS observations are used
- stations with GPS and GLONASS single frequency measurements:
only GLONASS observations are used (BISZ and RIOZ)
- Earth rotation parameters are fixed to their initial values
- GPS orbits from the IGS final solution are introduced and fixed (except
eclipsing GPS satellites
- Coordinates of only one station are fixed to their initials
in the determination of ORBITS
- Adjusted parameters:
- state vector of GLONASS satellites (and eclipsing GPS satellites)
- coordinate corrections
- tropospheric zenith path delay (4 h)
- y-bias, solar radiation scaling factor
- ambiguities
- STA and SV clock parameters of each observation epoch
- one clock bias per station and day
CLOCK ESTIMATION: IRKZ (OS0G for days 332 and 333) is used as time reference
no offset and trend correction is performed
ORBITS REPEATABILITY (cm):
(mean component error rms =sqrt((xrms**2 + yrms**2 + zrms**2)/3) )
