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 L1 and L2. If a cycle slip cannot be
fixed reliably, bad data points are removed or new
ambiguities are set up.
The a posteriori normalized residuals of the obser-
vations are checked for outliers, too. These obser-
vations are marked for the final parameter adjustment.
Basic Observable : GPS Carrier phase, code only used for receiver clock sync.
Elevation angle cut off :
up to week 0908: 10 degrees
since week 0908: 15 degrees
since week 1130: 10 degrees + elevation dependent weighting
since week 1400: 3 degrees + elevation dependent weighting,
GPS+GLONASS
Data sampling : 180 s in final solution
Since 08/2016: Input RINEX 2 and RINEX 3
Modelled : Double-differences, ionosphere-free linear combination
observable
Ground antenna : up to week 1400: Relative phase center corrections
phase center based on igs_01.atx model (no exceptions)
calibrations since week 1400: Absolute antenna phase center corrections
based on igs05.ayx model (exceptions for
stations with indiv. absol. calibrations
listed in epnc_05.atx) considering antenna
radome codes. If antenna/radome pair has no
available calibrations, the corresponding
values for the radome code "NONE" are used.
since week 1632: Absolute antenna phase center corrections
based on igs08.atx model (exceptions for
stations with indiv. absol. calibrations
listed in epnc_08.atx) considering antenna
radome codes. If antenna/radome pair has no
available calibrations, the corresponding
values for the radome code "NONE" are used.
since week 1934: Absolute antenna phase center corrections
based on igs14.atx model (exceptions for
stations with indiv. absol. calibrations
listed in epnc_14.atx) considering antenna
radome codes. If antenna/radome pair has no
available calibrations, the corresponding
values for the radome code "NONE" are used.
Satellite antenna : since week 1400: Absolute antenna phase centre corrections
phase center based on igs05.atx model.

Due to a bug in Bernese V4.2, the step 2 correction was
applied with a wrong time argument.
This causes annual variations with amplitudes of 1 cm in
station height (or correspondingly in the scale parameter
in case of minimum constraint solutions)
ROB solutions were corrected for the bug on week 1278
