4.6.3 Writing SINEX Files
4.7 Troposphere SINEX
SINEX files contain a subset of the information available in the Bernese normal equation files
(see Sections 22.10.2). The conversion of Bernese normal equations to SINEX is performed
by the combination program ADDNEQ2, which allows to store normal equation files as well
as SINEX files. For details see Section 9.4.9.1.
The SINEX files may contain additional information such as the 3-character identification
of the agency, the identification of the data source, as well as information concerning the
blocks “FILE/REFERENCE”, “FILE/COMMENT”, and “INPUT/ACKNOWLEDGMENTS”. A general file
(${X}/GEN/SINEX.), described in detail in Section 22.4.14, makes it possible to include this
information into the SINEX file automatically. Make sure that you adapt this file to your
agency/institution before writing SINEX files.
4.7 Troposphere SINEX
4.7.1 Definition
The Troposphere SINEX file format was developed to be used for the submission of troposphere
zenith delay solutions by the IGS Analysis Centers for the combination and for
distribution of the combined IGS product. The file contains information on tropospheric
zenith path delays of terrestrial stations. Currently the format version 0.01 is in use. The
format description may be found at
ftp://ftp.igs.org/igscb/data/format/sinex_tropo.txt.
Figure 4.9 shows an example for a Troposphere SINEX file.
4.7.2 Writing Troposphere SINEX Files
Troposphere SINEX files may be written by the parameter estimation program GPSEST
and by the normal equation combination program ADDNEQ2 (default extension TRO). In
addition both programs write troposphere files in Bernese format (default extension TRP).
No Bernese program reads Troposphere SINEX files.
The Troposphere SINEX files may contain additional information such as the 3-character
identification of the agency and information concerning the blocks “FILE/REFERENCE”. A
general file (${X}/GEN/SINEX.), described in detail in Section 22.4.14, makes it possible to
include this information into the Troposphere SINEX file automatically. Make sure that you
adapt this file to your agency/institution before writing Troposphere SINEX files.
4.8 IONEX
4.8.1 Definition
The IONEX (IONosphere EXchange) format was developed for the exchange of ionosphere
maps. A first version of the format was presented by [Schaer et al., 1996]. The currently
