6.5 Preprocessing Phase Observations
The following actions are defined corresponding to the settings in panel “MAUPRP 7: Clock
Events” for the handling of clock events:
CYC indicates a millisecond-jump that was repaired as a cycle slip,
MRK indicates that the corresponding observations are marked because the clock event may
bias the common clock estimation from code and phase observations, and
AMB reports the setup of a new ambiguity for all satellites because of a clock event.
6.5.8 Extraction (MPRXTR)
Program MPRXTR (”Menu>Processing>Program output extraction>Phase preprocessing”) extracts information
from the output of the program MAUPRP and produces a summary of the following
form:

The summary file contains one line per baseline processed. The line starts with the session,
a file sequence number, the “OK” flag, the first four characters of the station names, and
the length of the baseline. The line continues with some information concerning the epochdifference
solution: the number of observations, RMS, baseline change in the Cartesian X,
Y, and Z components. The next three fields contain the number of corrected cycle slips, the
number of deleted points, and the number of multiple ambiguities. Finally the maximum
residual for the ionosphere-free linear combination is given followed by the smallest corrected
cycle slip.
The last line of the summary gives the number of files, the mean baseline length, the mean
number of observations, the mean epoch-difference RMS, the mean number of corrected cycle
slips, the mean number of deleted points, and the mean number of multiple ambiguities.
The summary listing in the zero-difference case contains the RMS and coordinate corrections
from the epoch-difference solution for each individual station. All other parameters are
identical to the baseline case. If millisecond-jumps were detected in MAUPRP the events are
reported below the main table.
If a station or baseline was not successfully cleaned the flag will be different from “OK”
and the station/baseline should be removed. Apart from the summary file, MPRXTR may
create a deletion list file (in the case of preprocessing baseline files also a new baseline
definition file). This file is intended to be used for removing bad observation files in an
