20. Processing Examples
• Save the results in a kinematic coordinate file (option “Kinematic coordinates” in
panel “CODSPP 1.3: Output Files” )
PID 302 PPPEDT P:
• Introduce the kinematic solution from the previous step using option “Kinematic
coordinates” in panel “GPSEST 1.2: Input Files 2”
• Save the results in a “Kinematic coordinates” file
• Set the “Type of computed residuals” in panel “GPSEST 3.1: General Options 1” to
NORM APRIORI
• Enable the kinematic positioning with checkbox “Kinematic coordinates” in Section
“EPOCH PARAMETERS” of panel “GPSEST 5.1: Setup of Parameters and Pre-
Elimination 1” and set the “Pre-Elimination” to EVERY EPOCH
• Select the kinematic station in panel “GPSEST 6.5: Kinematic Coordinates”
• Constrain the solution to the a priori positions from the kinematic coordinates file
according to the already achieved accuracy (depends primarily on data quality
- from our experience the data quality decreases with increasing rover speed).
This value may be adapted during the iteration in this script (e.g., by using the
$bpe->putKey(); mechanism)
PID 303 GPSXTR: A filename for the “Kinematic summary” in panel “GPSXTR 2: Output Files”
may be added
PID 311 ...PID 522: These scripts are not necessary in kinematic mode and may be skipped
PID 901 PPP SUM ...PID 903 BPE CLN: Adapt these scripts to your needs.
The kinematic solutions from several stations may be merged by simply concatenating the
positions from the single kinematic coordinate files. A header section (e.g., from the first
file) must be included.
The clock RINEX files provided by the IGS contain satellite clock information with a sampling
of 300 seconds, only. Consequently, the resulting kinematic coordinate file from the
PPP.PCF can only contain a coordinate set every 5 minutes. The following scripts must be
modified to densify the solution up to 30 seconds:
PID 001 PPP COP: Copy the precise orbit, Earth orientation information, and clock RINEX
file from an IGS analysis center providing high rate satellite clock values (e.g., CODE)
instead of using the IGS combined products. It is recommended to modify the value
of the PCF-variable V B accordingly.
PID 212 RNXSMT P:
• Adapt option “Sampling interval for RINEX data” to generate a kinematic solution
with a sampling higher than 30 seconds.
• The parameter MAXREC=10000 in the main program ${FG}/RNXSMT.f limits
the number of epochs that can be analyzed in one program run. You may either
increase this number and compile the program or limit the processing to a shorter
observation interval with option “Use observation window”. Alternatively you may
cut the RINEX observation file using program CCRINEXO.
