MEASUREMENT MODELS
-----------------------------------------------------------------------------
Preprocessing : Phase preprocessing in a baseline by baseline mode
using triple-differences. In most cases, cycle slips
are fixed looking simultaneously at different linear
combinations of two frequencies. If a cycle slip cannot
be fixed reliably, bad data points are removed or new
ambiguities are set up. In addition, a data screening
step on the basis of weighted postfit residuals is
performed. Outliers are removed.
Basic Observable : GPS/GLONASS/Galileo(/BDS/QZSS) carrier phase; code only
used for receiver clock synchronization and MW
ambiguity resolution
Priorities for observation selection:
G L1 L1W L1C L1X
G L2 L2W L2C L2D L2P L2X L2S L2L
G C1 C1W C1C C1X
G C2 C2W C2C C2D C2P C2X C2S C2L
R L1 L1P L1C L1X
R L2 L2P L2C L2X
R C1 C1P C1C C1X
R C2 C2P C2C C2X
E L1 L1C L1X
E L2 L5Q L5X L5I
E C1 C1C C1X
E C2 C5Q C5X C5I
|--------------------------------------------------------|
Elevation angle cutoff : 3 degrees
Sampling rate : 3 minutes
Weighting : 6 mm for double-differenced
ionosphere-free phase
observations at zenith;
elevation-dependent weighting
function 1/cos(z)**2
Modelled : Double differences, ionosphere-free linear combination
observable of two frequencies (see selection above)
Ground antenna : "absolute" elevation- & azimuth-dependent (when
phase center available) PCVs & offsets from ARP applied from
calibrations file igs20_wwww.atx
Receiver antenna models GNSS-specific correctiopns are
applied (as far as available).
Final: Observations without antenna corrections for the
related GNSS are ignored
Calibration applied if given in file igs20_wwww.atx;
otherwise radome effect neglected (radome => NONE)
Final: Stations with a not calibrated antenna/radome
combination are ignored
Troposphere : ECMWF-based hydrostatic delay mapped with hydrostatic
VMF3. Coefficients from 3-hourly global grids.
GPT3/GMF3 in the rapid and ultra-rapid solution.
Gradient model: none
Ionosphere : 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.
-----------------------------------------------------------------------------
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 : since week 1934 : BRUX, GRAS, METS, PENC, POLV, SOFI
coordinates used for minimum constraints to IGS14
Troposphere : Zenith delay: estimated for each station in intervals
of 2 hours. Loose relative constraints of
5 m are applied. Piece-wise, linear
parametrization, allowing for connection
of the parameters at day boundaries.
|--------------------------------------------------------|
Zenith delay epochs: every two hours starting at
midnight
|--------------------------------------------------------|
Mapping function: wet VMF3 for final; GMF3 for rapid
|--------------------------------------------------------|
Gradients: pairs of horizontal delay gradient
parameters are estimated in N-S and E-W
direction for each station in intervals of
24 hours. Loose relative constraints of
5 m are applied. Piece-wise, linear
parametrization, allowing for connection of
the parameters at day boundaries.
Details about the gradient model can be
found in Rothacher et al. (1997).
Refined gradient model used, see Chen and
Herring (1997).
Ionospheric : Not estimated in ionosphere-free analyses
correction
One scaling factor for 2nd and 3rd order terms and ray
bending is setup to switch the components on or off
on normal equation level.
The products are generated with considering all three
correction components.
Ambiguity : Ambiguities are resolved in a baseline-by-baseline
mode performing the following steps:
. Melbourne-Wuebbena approach (< 6000 km)
. Quasi-Ionosphere-Free (QIF) approach (< 2000 km)
(also for GLONASS, same frequencies)
. Phase-based widelane/narrowlane method (< 200 km)
(also for GLONASS, no restrictions)
. Direct L1/L2 method, also for GLONASS (< 20 km)
(also for GLONASS, no restrictions)
GNSS-derived global ionosphere map information is used
to support the code-less methods.
Satellite clock : Satellite clock corrections are not estimated but
bias eliminated by forming double differences.
Receiver clock : Receiver clock corrections are estimated as part of the
bias preprocessing using code measurements. They are finally
eliminated by forming double differences.
Orbits and ERPs : CODE final GNSS orbit and ERP information is adopted.
Tidal : Solid earth tidal displacements are modeled according to
displacements IERS 2010 conventions. Ocean loading corrections are
computed based on Scherneck's amplitudes and phases. No
atmospheric loading corrections are taken into account.
