The well-established, mature codebase is mostly written in C++ language. Its publication under GNU GPL is thought to be well-suited for test, validation and demonstration of new approaches in precise real-time satellite navigation when IP streaming is involved.

-In February 2014 the overall responsibility at BKG for the concept and realization of BNC was handed over from Georg Weber to Axel RÃ¼lke. He is in charge now for guiding the application and further evolution of the software in view of appearing new satellite navigation systems and services.
+The well-established, mature codebase is mostly written in C++ language. Its publication under GNU GPL is thought to be well-suited for test, validation and demonstration of new approaches in precise real-time satellite navigation when IP streaming is involved. Commissioned by a German governmental agency, the overall intention has been to push the development of RTCM Recommended Standards to the benefit of IAG institutions and services such as IGS and the interested public in general.

-Observations will be converted to RINEX if they come in either RTCM Version 2 or RTCM Version 3 format. Depending on the RINEX version and incoming RTCM message types, files generated by BNC may contain data from GPS, GLONASS, Galileo, SBAS, QZSS, and/or BDS (BeiDou). In case an observation type is listed in the RINEX header but the corresponding observation is unavailable, its value is set to zero '0.000' or left blank. Note that the 'RINEX TYPE' field in the RINEX Version 3 Observation file header is always set to 'M(MIXED)' or 'Mixed' even if the file only contains data from one system.

-<p>
-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. 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 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 'Skeleton Mandatory') and switch to a default selection of observation types when such file is not available or does not contain the required information.

-Please note that RTCM Version 3 messages 1084 for GLONASS observations do not contain the GLONASS channel numbers. These observation messages can only be converted to RINEX when you add messages which include the channel numbers. This could be done by means of an additional stream carrying 1087 GLONASS observation messages or an additional stream carrying 1020 GLONASS ephemeris messages. You could also consider setting up a stream which contains both, the 1084 and the 1020 messages.

-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' would mean to not convert the affected stream but save its content as received. The 'SSL Error' recorded in the 'Log' tab is caused by the fact that observation stream downloads from IGS and MGEX Broadcasters initiate the download of RINEX skeleton files from a HTTPS (TLS/SSL) website and BNC has been configured in this example to ignore SSL errors as shown in the preceding 'Network' panel screenshot.

-Sometimes public RINEX header skeleton files are not available, their content is not up to date, or you need to put additional/optional records in the RINEX header. For that, BNC allows using personal skeleton files that contain the header records you would like to include. You can derive a personal RINEX header skeleton file from the information given in an up to date sitelog. A file in the RINEX Observations 'Directory' with a 'Skeleton extension' suffix is interpreted by BNC as a personal RINEX header skeleton file for the corresponding stream.
