20. Processing Examples
• (optional) conversion of station coordinate results to a predefined epoch,
• generation of merged coordinate and velocity files by adding new stations to existing
(reference) coordinate/velocity files.
The PCF writes a processing summary file PPPyyssss.PRC (yy=year, ssss=session).
The basic requirement is that all processed receiver and antenna names are listed in the
${X}/GEN/RECEIVER. and the ${X}/GEN/PHAS COD.I01 file.
Some BPE variables serve as options to this PCF:
V CRDREF: name of the coordinate (and velocity) file (e.g., IGS 00 R) that is used as reference.
This file should contain the stations representing the reference frame.
V CRDMRG: name of the resulting merged coordinate (and velocity) file (e.g., IGS 00). Reference
stations are merged into these files without changes, even if a station is included
into the PPP processing. The resulting coordinates (and velocities) from the PPP of
all other sites are added.
V STAINF: name of the station information file (e.g., EXAMPLE.STA) in the campaign’s STA
directory. If left blank, the station information is gathered from the RINEX files
without further verification. Note that this file may be used to rename stations that
are written into the resulting coordinate (and velocity) files.
V PLDINF: name of the tectonic plate definition file (e.g., EXAMPLE.PLD) in the campaign’s
STA directory. If set, the station coordinate results are referred to epoch 2000.0, otherwise
they are referred to the actual observation epoch.
V BLQINF: name of the ocean loading coefficients file (e.g., EXAMPLE.BLQ) in the campaign’s
STA directory. If set, station specific ocean loading corrections are applied and missing
stations are reported in the processing summary file (PPPyyssss.PRC).
V ABBINF: mandatorily set to the station name abbreviation file (e.g., EXAMPLE.ABB). The
BPE automatically adds new 4- and 2-character abbreviations for stations not yet
listed in this file.
V PCV: name of the antenna phase center model used within the BPE (e.g., I01, see Section
16.2.5 for more details).
The requested files are available in the example campaign. When processing your own data,
these files need to be generated (using, e.g., ”Menu>Campaign>Edit station files”), or downloaded
from appropriate sources in the internet). We refer to Chapter 22 for more details.
The analysis results are output in the following formats:
• normal equation files, station coordinates, troposphere parameters, P1-P2 DCBs, and
NNR-NUVEL model station velocities in Bernese formats,
• zenith path delay (ZPD) values in tropospheric SINEX format,
• station clock information in clock RINEX format,
• coordinates in SINEX format.
