4.8.2 Writing IONEX Files
Figure 4.10: Example for a IONEX file.
4.8 IONEX
IONEX files are written by the parameter estimation program GPSEST and the normal
equation combination program ADDNEQ2 (default extension INX) in addition to ionosphere
files in Bernese format (default extension ION). No Bernese program reads IONEX files.
The IONEX files contains additional information such as the identification of the agency,
comment lines, or the definition of the data grid. A general file (${X}/GEN/IONEX.), described
in detail in Section 22.4.15, makes it possible to include this information into the
IONEX file automatically. Make sure that you adapt this file to your agency/institution
before writing a IONEX files.
