14.3.2 Basic Processing of Clock RINEX Files
The basic function of the program CCRNXC is to read clock RINEX files generated by other
Bernese programs or obtained from external sources. After manipulating the files the results
are written again to a clock RINEX file. The satellite clocks may be stored in a Bernese
satellite clock file, too.
Only the clock records for the user specified time interval (option “Use time window” in panel
“CCRNXC 2: Clock/Epoch Selection for Processing”, see Figure 14.5) are read. If no time window
is specified all records from the input files are imported. The output clock records are either
initialized for the user specified time window or the total time interval covered by all selected
clock RINEX input files.
An equidistant sampling of the epochs in the output clock file is imposed. It is either computed
from the sampling of the input clock RINEX files or the user value from option
“Sampling rate for clocks” in panel “CCRNXC 2: Clock/Epoch Selection for Processing” (see Figure
14.5) is used. If you specify a sampling in this input field it has to be compatible to the
sampling in the input files. Only those records from the input files are processed for which
an epoch in the output array is defined.
In the section “DEFINE A LIST OF CLOCKS TO BE PROCESSED” in panel “CCRNXC 2:
Clock/Epoch Selection for Processing” (see Figure 14.5) you may specify a subset of clocks
to be processed. All other clocks are skipped when reading the input clock RINEX files.
The only exception is that the reference clocks from all input clock RINEX files are pro-
