20. Processing Examples
the loop, detected outliers are marked by SATMRK using the edit information file
ED1iyyssss.EDT generated by RESRMS.
The number of loops is limited by PARAM2. If PARAM2 is undefined, the loop is skipped.
PID 302 CLKEDT: The script is repeated but the options for the programs are different.
In the second iteration the threshold for the outlier detection in program RESRMS is
decreased.
Note when processing your own data: While it is preferable to process all stations in one
program run, this may not be possible if a large number of stations is involved. In this case,
you may split the network into clusters, e.g., using the program MKCLUS (description in
Section 19.12.1.4). For data screening, regional clusters are recommended to have as many
redundant observations as possible to get as reliable residuals as possible.

20.4.4.6 Compute Final Solution, Select Reference Clock, and Check Results
Now that the data screening is finished, a final solution can be computed.

PID 401 GPSEST: The script runs GPSEST for generating the final solution. Clock RINEX
and residual files result.
PID 402 GPSXTR: A summary of the GPSEST run is extracted for the final protocol file.
The a posteriori rms should be approximately 1 mm.
PID 403 RESRMS: A residual statistics of the final solution is created with RESRMS. This
overview is contained in the processing summary.
PID 411 CCRNXC: Program CCRNXC identifies the best reference clock among all station
clocks and generates the final clock solution file (clock RINEX and Bernese clock file).
The processing summary contains the resulting CCRNXC output providing information
on the selected reference clock and the performance of a polynomial fit of the estimated
clock corrections.
PID 421 CODSPPAP: This is the parallelization script for CODSPP.
