Data Files
During a data recording session, all the data for that session is stored on the SD
memory card as a U-file. The U-file is a compressed file that contains the data that is
converted to individual files during the download process. These files include: the raw
data files (B-files) that store all carrier and code phase data, ephemeris files (E-files)
that store satellite position and timing information, and a site information files (S-files)
that store site occupation information. The B-, E-, S- and ALM files are standard files
that are recorded during virtually every session. If the receiver is an RTK rover, the
receiver creates and stores the CBEN file containing RTK solution records and the
OBEN solution vector files. An event file (D-file) is created if the receiver is collecting
attribute or event driven data. Lastly, the receiver creates and stores an almanac file
(ALM file) that stores satellite almanac data used by the Mission Planning program.
Table 4.5 provides a summary of the file types, including file names, a description of
the information contained in the files, and the file format.
