4.6.3 Writing SINEX Files<br />

4.7 Troposphere SINEX<br />

SINEX files contain a subset of the information available in the <strong>Bernese</strong> normal equation files<br />

(see Sections 22.10.2). The conversion of <strong>Bernese</strong> normal equations to SINEX is performed<br />

by the combination program ADDNEQ2, which allows to store normal equation files as well<br />

as SINEX files. For details see Section 9.4.9.1.<br />

The SINEX files may contain additional information such as the 3-character identification<br />

of the agency, the identification of the data source, as well as information concerning the<br />

blocks “FILE/REFERENCE”, “FILE/COMMENT”, and “INPUT/ACKNOWLEDGMENTS”. A general file<br />

(${X}/GEN/SINEX.), described in detail in Section 22.4.14, makes it possible to include this<br />

information into the SINEX file automatically. Make sure that you adapt this file to your<br />

agency/institution before writing SINEX files.<br />

4.7 Troposphere SINEX<br />

4.7.1 Definition<br />

The Troposphere SINEX file format was developed to be used for the submission of troposphere<br />

zenith delay solutions by the IGS Analysis Centers for the combination and for<br />

distribution of the combined IGS product. The file contains information on tropospheric<br />

zenith path delays of terrestrial stations. Currently the format version 0.01 is in use. The<br />

format description may be found at<br />

ftp://ftp.igs.org/igscb/data/format/sinex_tropo.txt.<br />

Figure 4.9 shows an example for a Troposphere SINEX file.<br />

4.7.2 Writing Troposphere SINEX Files<br />

Troposphere SINEX files may be written by the parameter estimation program <strong>GPS</strong>EST<br />

and by the normal equation combination program ADDNEQ2 (default extension TRO). In<br />

addition both programs write troposphere files in <strong>Bernese</strong> format (default extension TRP).<br />

No <strong>Bernese</strong> program reads Troposphere SINEX files.<br />

The Troposphere SINEX files may contain additional information such as the 3-character<br />

identification of the agency and information concerning the blocks “FILE/REFERENCE”. A<br />

general file (${X}/GEN/SINEX.), described in detail in Section 22.4.14, makes it possible to<br />

include this information into the Troposphere SINEX file automatically. Make sure that you<br />

adapt this file to your agency/institution before writing Troposphere SINEX files.<br />

4.8 IONEX<br />

4.8.1 Definition<br />

The IONEX (IONosphere EXchange) format was developed for the exchange of ionosphere<br />

maps. A first version of the format was presented by [Schaer et al., 1996]. The currently<br />
