Soehne SOLUTION CHARACTERISTICS - Software used : EPOS.P.V2 - Data used: - undifferenced carrier phases - the following observations are used: - stations with GPS and GLONASS dual frequency measurements: all observations are used except for SVT3, MDOA and GATR: only GLONASS 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, with lower weighting - Earth rotation parameters are fixed to the estimated values of IGS - GPS orbits from the IGS final solution are introduced and fixed (except eclipsing GPS satellites) - Coordinates of only one station (ZIMZ) 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 - nine radiation pressure parameters per satellite - The orbit parameter stem from the middle day of a 3-day-solution CLOCK ESTIMATION: IRKZ is used as time reference no offset and trend correction is performed The orbit files (gfx09940.sp3 - gfx09946.sp3) and this summary file (gfx09947.sum) are available at CDDIS (directory /products/0994).
