Regarding the RINEX Version 2 file header, BNC simply introduces all observation types defined in the Version 2 standard and later reports "0.000" for all observations which are not received. However, following this approach is not possible for RINEX Version 3 files from RTCM Version 3 MSM streams because of the huge number of observation types which might in principle show up. The solution implemented in BNC is to start with RINEX Version 3 observation type records from skeleton files (see section 'Skeleton Extension' ) and switch to a default selection of observation types when such skeleton file is not available or does not contain the required information. The following is a default selection of observation types specified for a RINEX Version 3 file:642 It is important to understand that converting RTCM streams to RINEX files requires a-priori information on observation types for specifying a complete RINEX header.

Specifying a decoder string 'ZERO' means to not convert the affected stream but save its contents as received. 661 </p> 659 The screenshot below shows an example setup of BNC when converting streams to RINEX. Streams are coming from various NTRIP Broadcasters as well as from a serial communication link. Specifying a decoder string 'ZERO' means to not convert the affected stream but save its contents as received. Note that one RTCM Version 2 stream in this example is forced to be saved in RINEX Version 3 format. Although it is possible to do this it is not recommended because RTCM Version 2 streams can not be precisely mapped to this file format, see Section 'Version 2' below for details. 660 </p> 661 662 662 <p><img src="IMG/screenshot16.png"/></p> 663 663 <p><u>Figure 7:</u> BNC translating incoming streams to 15 min RINEX Version 3 files.</p> … … 788 788 <p> 789 789 790 <p><a name="rnxscript"><h4>3.4.6 Script - optional</h4></p> 790 <p><a name="sklMandat"><h4>3.4.6 Skeleton Mandatory - optional</h4></p> 791 <p> 792 Tick check box 'Skeleton mandatory' in case you want that RINEX files are only produced if skeleton files are available for BNC. If no skeleton file is available for a particular source then no RINEX observation file will be produced from the affected stream. 793 </p> 794 <p>Note that a skeleton file contains RINEX header information such as receiver and antenna types. In case of stream conversion to RINEX Version 3 a skeleton file should also contain information on potentially available observation types. A missing skeleton file will therefore enforce BNC to only save a default set of RINEX 3 observation types. 795 </p> 796 797 <p><a name="rnxscript"><h4>3.4.7 Script - optional</h4></p> 791 798 <p> 792 799 Whenever a RINEX Observation file is saved, you might want to compress copy or upload it immediately via FTP. BNC allows you to execute a script/batch file to carry out these operations. To do that, specify the full path of the script/batch file here. BNC will pass the RINEX Observation file path to the script as a command line parameter (%1 on Windows systems, $1 on Unix/Linux/Mac OS X systems). … … 799 806 </p> 800 807 801 <p><a name="rnxvers2"><h4>3.4. 7Version 2 - optional</h4></p>802 <p> 803 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 processing and default outputformat for BNC, there are two applications where the program is required to produce data in RINEX Version 2 format:808 <p><a name="rnxvers2"><h4>3.4.8 Version 2 - optional</h4></p> 809 <p> 810 GNSS observation data are generally hold available within BNC according to attributes as defined in RINEX Version 3.
