PID 201 RNXGRA: A summary of all available observation data is created, giving a complete<br />

overview of observed satellites, involved stations and their performance. This file<br />

appears in the processing summary and may help to identify possible data tracking<br />

problems of observing sites.<br />

Note for processing your own data: This script also removes stations with data problems<br />

from the processing. Stations showing large data gaps are detected by RNXGRA<br />

and listed in a deletion file (GRAyyssss.DEL in directory OUT). This list is used by the<br />

BPE script to delete the corresponding RINEX observation files from the RAW directory.<br />

The observation summary appears in the processing summary and may help to<br />

identify possible data tracking problems of observing sites. All deleted stations are<br />

reported, too.<br />

PID 211 RNXSMTAP: This script prepares the list of input files for the parallel run of<br />

RNXSMT. Already existing smoothed RINEX files (SMT) and the file RNXyyssss.ERR<br />

for the current session are deleted. The number of parallel jobs and the number of<br />

files processed within one job is controlled by the BPE variable V CLU. If it is not set,<br />

one RNXSMT will be executed for each RINEX file (processing station-by-station). If<br />

set to a positive number it defines the number of stations making up a cluster. These<br />

clusters are processed in parallel in PID 212.<br />

PID 212 RNXSMT P: This script starts RNXSMT for the prepared clusters or files. The<br />

program smoothes the code observations using phase measurements. Cycle slips and<br />

outliers are detected using simultaneously code and phase observations from both<br />

frequencies.<br />

PID 221 SMTBV3AP: Prepares the parallelization of RXOBV3. Instead of the original<br />

RINEX observation files the available smoothed RINEX files are used to create the<br />

clusters for running RXOBV3.<br />

PID 222 SMTBV3 P: This script starts RXOBV3 for the prepared clusters or files to convert<br />

the smoothed RINEX files into <strong>Bernese</strong> observation files. The program compares the<br />

data records in the RINEX header with the entries in the station information file. Any<br />

detected header inconsistency is reported in the processing summary.<br />

Note for processing your own data: In case of inconsistencies the BPE stops with an<br />

error (options “ACTIONS IN CASE OF INCONSISTENCIES” set to ERROR). This setting<br />

requires manual interaction to resolve any inconsistency (e.g., with an entry in a<br />

special file, specified in panel “RXOBV3 5.2: Check Content of RINEX Header 2”, see 22.8.4).<br />

Alternatively you may set the options to SKIP which is the robust setting to generate<br />
