PROCESSING SCHEME:
------------------------------------------------------------------------------
SOFTWARE:
Bernese GPS Software
ORBIT COMPUTATION:
Double difference phase observations of GLONASS and GPS satellites are
processed in the ionosphere free linear combination.
IGS orbits and Earth rotation parameters are fixed.
Six initial conditions and five (nine for GPS weeks 0980-1082)
radiation pressure parameters per GLONASS satellite are determined.
The middle day of a 3-day-arc is used for the daily orbit results.
The daily orbit files include GPS satellite clock values from IGS
estimates and broadcasted values for GLONASS satellite clocks.
The coordinates of the following stations are contrained to ITRF-97:
GODZ IRKZ LHAZ OS0G YARR ZIMZ WTZZ.
GLONASS/GPS TIME OFFSET:
Code observations of combined GLONASS/GPS receivers are used to
determine the GLONASS/GPS time offset.
This offset includes the modulo 1 sec system time scale difference of
GLONASS and GPS and an additional offset between the receiver's
'GPS clock' and 'GLONASS clock'. The additional offset is receiver
dependent.
TRANSFORMATION PARAMETERS BETWEEN ITRF AND PZ90:
The transformation parameters are derived from GLONASS precise orbits
(given in ITRF) and GLONASS broadcast orbits (given in PZ90).
