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. Further reading: Chapter 3: Campaign Setup (page 43), Section 18.5: Menu Variables (page 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. Page 426 AIUB
20.3.3 What to do in Case of Errors 20.4 Description of the Processing Examples The example PCFs will normally run without any error, provided that the installation was done correctly, no manual changes have been introduced in any files, and the required files are available. Nevertheless, errors may (and sooner or later almost certainly will) occur, mainly when you run the BPE on your own data, or have modified the examples according to your needs (which we actually recommend to do). In Section 19.11 we provide numerous hints on how to solve a variety of possible problems. 20.4 Description of the Processing Examples The Process Control Files (PCF) contain a list of scripts from the ${U}/SCRIPT directory to be executed in a well-defined order by the BPE server. These scripts constitute modular building blocks, allowing to concoct complete processing schemes (PCFs) tailored to specific needs. In essence, a script runs one (or more) Bernese programs (e.g., the script COOVEL runs the Bernese program COOVEL). Program input options are taken from the directory specified in the PCF. The BPE, furthermore, allows to control the processing flow of the user scripts (sequence, loops, interdependencies, parallelization, etc.). BPE variables, which can be used in the program input option panels, e.g., for filename creation, are specified in the PCF. These variables always have the prefix V . For details be referred to Chapter 19. The following sections on the example PCFs provide an overview and descriptions of the scripts in logically connected blocks. 20.4.1 Precise Point Positioning (PPP.PCF) The main purpose of this PCF is to perform a precise point positioning (PPP) using RINEX GNSS observations from a number of stationary ground receivers to obtain a set of station coordinates at a cm-level. This will be used as a priori information for the double-difference analysis done by RNX2SNX.PCF, described in Section 20.4.2. Additional tasks performed by the PPP.PCF are: • determination of phase-consistent receiver clock offsets in 5-minute intervals for time transfer, • extraction of TEC (total electron content) information (station-specific and regional ionosphere models), • estimation of receiver differential code bias (DCB) P1-P2 values, • computation of a common translation vector related to the PPP-based station coordinates. This PCF is well suited as a preparatory BPE processing step, due to the following features: • (optional) detection of missing station entries in the ocean loading correction file (extension BLQ), • update of the station name abbreviation table (extension ABB), Bernese GPS Software Version 5.0 Page 427
