20. Processing Examples
20.3.1 How to run the Examples
After installation, you will have to set the example campaign as active campaign:
• enter ${P}/EXAMPLE in the list of campaigns, ”Menu>Campaign>Edit list of campaigns”. You
always have to specify the path (${P}) here.
• select the example campaign as active campaign: ”Menu>Campaign>Select active campaign”.
Use ”Menu>Configure>Set session/compute date” to set the current session. Enter year 2002, and day
of year 143 for the first of the 4 days of the example campaign. If necessary, specifySESSIONS
for the session table, and specify 0 as session character. No other information is needed.
You can now run the first of the example PCFs, the PPP.PCF, for the first session by ”Menu
>BPE>Start BPE process”. The following four input panels are involved in this step:
BPE 1: Here, you can verify the active campaign and session. No change in any options
should be necessary.
BPE 2: Verify the name of the “CPU control file”. This should be USER.CPU 1 . Select the
PPP.PCF in the option “Process control file”. For now the other fields may remain
empty. Consult the online help for more information on these options.
BPE 3: The option “Task ID” allows to specify a prefix to the BPE log files in the campaign’s
BPE directory, which is helpful to keep an overview of the runs. For the PPP.PCF, a
natural choice would be, e.g., PP. The “Status file” displays the step-by-step progress
of the BPE. This progress is displayed on screen, but it’s often useful to save this
information also in a file. An obvious choice at this point is PPP.RUN. A similarly
evident name (PPP) may be chosen for the “Program output”.
BPE 4: Displays a list of variables defined in the PCF. Do not change any of these for now.
After filling in the options, the BPE can be started. The progress window will show up,
displaying the status of the step-wise processing.

363), Section 19.4: CPU Control File (page 386), Section 19.8.1: Interactive Mode (page
410).
20.3.2 Verification Using Provided Reference Solutions
After completion of the BPE, you can compare the results with the supplied reference
solutions in the campaign directories (SOL, ATM, STA, and ORB). It is important that the
PPP.PCF for session 1430 of year 2002 is run first, otherwise your solutions will be based on
other a priori coordinates (which has no impact on the results, but will lead to differences
in several program outputs compared to the reference files). The other example PCFs are
based on the PPP results for session 1430, year 2002.
1 The CPU control files may be adapted to the user’s computer system according to the description in
Section 19.4. Note that after installation, the CPU file should be correct for your platform type (UNIX
or windows). The UNIX version of this file should work, but be aware that several ways exist to improve
performance.
