    1604 GNSS observation data are generally hold available within BNC according to attributes as defined in RINEX Version 3. These attributes describe the tracking mode or channel when generating the observation signals. Capital letters specifying signal generation attributes are A, B, C, D, I, L, M, N, P, Q, S, W, X, Y, and Z, see RINEX Version 3 documentation. Although RINEX Version 3 with its signal generation attributes is the internal default processing format for BNC, there are two applications where the program is explicitly required to produce data files in RINEX Version 2 format:
     1600<p><h4 id="rnxvers3">2.4.8 Version 3 - optional</h4></p>
     1601<p>
     1602The default format for RINEX Observation files is RINEX Version 3. There is nothing to activate in addition to save RTCM Version 3 observation streams in RINEX Version 3 format.
     1603</p>
     1604
     1605<p>
     1606Note, that it is possible to force an RTCM Version 2 stream to be saved in RINEX Version 3 file format. However, this is not recommended, because such stream cannot be precisely mapped to RINEX Version 3 as the required information on tracking modes (observation attributes) is not part of RTCM Version 2.

     1611GNSS observation data are generally hold available within BNC according to attributes as defined in RINEX Version 3. These attributes describe the tracking mode or channel when generating the observation signals. Capital letters specifying signal generation attributes are A, B, C, D, I, L, M, N, P, Q, S, W, X, Y, and Z, see RINEX Version 3 documentation. Although RINEX Version 3 with its signal generation attributes is the internal default processing format for BNC, there are two applications where the program can be setup to produce data files in RINEX Version 2.11 format:
    16051612<ol type="1">
    16061613<li>When saving the content of incoming observation streams in RINEX Version 2 files as described in this section.</li>
    16071614<li>When editing or concatenating RINEX 3 files to save them in Version 2 format, see section on 'RINEX Editing & QC'.</li>
    16081615</ol>
    1609 As the Version 2 format ignores signal generation attributes, BNC is forced to somehow map RINEX Version 3 to RINEX Version 2 although this cannot be done in one-to-one correspondence. Hence we introduce a 'Signal priority' list of attributes (characters, forming a string) for mapping Version 3 to Version 2.
     1616Select RINEX 'Version 2' if you would like to save RTCM Version 3 observation streams in RINEX Version 2 format.

    1656 Broadcast Ephemeris can be saved in RINEX Navigation files when received e.g. via RTCM Version 3 message types 1019 (GPS) or 1020 (GLONASS) or 1044 (QZSS) or 1043 (SBAS) or 1045 and 1046 (Galileo) or 63 (BDS/BeiDou, tentative message number). The filename convention follows the details given in section 'RINEX Filenames' except that the first four characters are 'BRDC'.

    17461739When specifying several input files, BNC will concatenate their contents. In case of RINEX Observation input files with different observation type header records, BNC will output only one set of adjusted observation type records in the RINEX header which fits to the whole file content.

    1749 Note that you may specify several RINEX Version 2 Navigation files for GPS and GLONASS.
