In most cases cycle slips are fixed looking simultaneously at different linear combinations of L1 and L2. If a cycle slip cannot be fixed reliably, bad data points are removed or new ambiguities are set up. Observations with higher a posteriori residuals are omitted from the final parameter adjustment. Basic Observable : Carrier phase, code only used for receiver clock sync. Elevation angle cutoff : up to week 1400 : 10 deg. + elev.dep.wgt. since week 1400 : 3 deg. + elev.dep.wgt. Sampling rate : 180 sec. Modelled : Double-differences, ionosphere-free linear combination. observable Ground antenna : up to week 1400 : relative PCV models, based on IGS_01 phase center (no exceptions) calibrations since week 1400 : absolute PCV models, based on IGS_05 (exceptions: with indiv. abs. calibrations listed in epnc_05.atx), considering radome codes since week 1632 : absolute PCV models, based on IGS_08 (exceptions: sets with indiv. abs. calibrations listed in epnc_08.atx), considering radome codes Satellite antenna: since week 1400 : absolute APCV models, based on IGS05 solution phase center calibrations since week 1632 : absolute APCV models, based on IGS08 solution Troposphere : up to week 1390 : no a priori model, estimating zenith path delays with 1 hour interval/site, using Niell mapping function, no apriori sigmas, computing daily TRO files with coordinates from the weekly solution since week 1390 : dry-Niell a priori model, estimating zenith path delays with 1 hour interval/site, and horizontal gradient parameters with 1 day interval/site using wet-Niell mapping function, no apriori sigmas, computing daily TRO files with fix coordinates from the cummulative weekly solution Ionosphere : up to week 1390 : calculating regional ionospheric model since week 1390 : ION model from CODE is used This model is used only for ambiguity resolution. Ionosphere is not modelled in final solution - eliminated by iono-free linear combination of L1 and L2. Ocean loading : up to week 1400 : GOT00 since week 1400 : FES2004 Atmosph. loading : not applied Solid Earth tides: applied, according to IERS Conventions96/2000 Orbits and ERPs : IGS final orbits and ERPs, DE200 planetary ephemerides, JGM3 model are used. ----------------------------------------------------------------------------- ESTIMATED PARAMETERS (APRIORI VALUES & SIGMAS) ----------------------------------------------------------------------------- Adjustment : weighted least-squares algorithms Rejection Criter.: Outliers are detected during pre-processing steps, thus there is no rejection in the final parameter estimation. Station : up to week 1400 : GRAZ constrained to the actual epoch of ITRF00 coordinates since week 1400 : BRUS, BUCU, GRAS, GRAZ, METS, PENC, SOFI, UZHL used for minimum constraints to IGS05 since week 1632 : BRUS, GRAS, METS, PENC, POLV, SOFI used for minimum constraints to IGS08 Troposphere : see above Ionosphere : not modeled in the final solution, only used for ambiguity resolution Ambiguity : QIF strategy used to resolve ambiguities in a baseline processing mode. The resolved ambiguities are introduced in the final network solution. Not resolved ambiguities are solved for without any constraints. Satellite clock : Satellite clock biases are not estimated but bias eliminated by forming double-differences. Receiver clock : Receiver clock corrections are estimated during the bias pre-processing using code measurements. -----------------------------------------------------------------------------
