snx2site - converts a SINEX file to the site_info/xsites format

snx2site {-achr -o out_file -s in_file -f frame_name -v val_mjd} SINEX_file(s)
where:
-a = create antenna records only (default: all types),
-c = create coordinate records only (default: all types),
-h = help message,
-o = output file name (default: snx2site.out),
-r = create receiver records only (default: all types),
-s = old site_info file (for initialization),
-v = valid date to begin using this info [MJD].

DESCRIPTION

NOTES: It remains the users responsibility to verify the output information.

• Antenna names are not standardized! snx2site attempts to convert non-standard names to those used at NOAA/NGS. If a standard to non-standard match can not be made, the antenna name is written as it appears in the SINEX file.
• Certain information is not (uniquely) defined in the SINEX format. This information includes:
  • the tectonic plate,
  • the reference frame,
  • equipment installation dates (val or valid dates),
  • and frequently, no site velocity values.
  This info will be set to zero or left blank depending upon the data type. Installation dates will be set to January 1, 1980. A user selected frame and/or val date can be entered through the command line.
• In addition, some SINEX files are created for special purposes and may not contain complete coordinate - antenna - receiver information.

EXAMPLES

Simple conversion to default output file snx2site.out

snx2site igs09407.snx

Simple conversion to the user specified output file site_info.tst

snx2site -o site_info.tst igs09407.snx

Convert to the specified output file site_info.tst; the frame and val date are also entered on the command line (Note: the command processing and substitution "-v $(mjd 98 3 1)" works in the ksh and bourne shells)

snx2site -o site_info.tst -f ITRF96 -v $(mjd 98 3 1) igs09407.snx

Convert only coordinate information.

snx2site -c igs09407.snx
