RINEX Utility – Rev B
RINEX requires the file naming convention to follow a specific format. The easiest way to
relate files is to use the same name convention for all related files in a given directory
and to use separate directors for files recorded on the same date. The file naming
convention is as follows:
9 File names are limited to 8 characters followed by a 3 character extension (MS-DOS
compatible; ssssddd0.yyt)
9 ssss = a unique file identifier. All four characters must be used. If less than 4
characters are used, enter “_” (underscore) to fill the space. Any alpha-numeric
character is acceptable (A-Z and 0 -9)
9 ddd = the julian date of the year; i.e. March 23, 2007 = julian date 082
9 0 = required fill character
9 yy = last two digits of the calendar year
9 t = file type; the output files will be tagged as either O for observation or N for
navigation
In a similar fashion, the Output Directory button tells the RINEX Utility where to place
the converted files when the process is complete. Most users create a sub-directory in
their data folder, so that related data sets stay together. Set the path to the folder where
the converted files are to be placed. Figure 3 depicts a typical window display.
