BNC has been written under GNU General Public License (GPL). Source code is available from Subversion software archive -ntrip.org/svn/trunk/BNC. Binaries for BNC are available for Windows, Linux, and Mac OS X systems. We used the MinGW Version 4.4.0 compiler to create the Windows binaries. It is likely that BNC can be compiled on other systems where a GNU compiler and Qt Version 4.8.4 or any later version are installed. Please ensure that you always use the latest precompiled version of BNC available from Note that static and shared builds of BNC are made available. A static build would be sufficient in case you don't want BNC to trace PPP results using Google Map (GM) or OpenStreetMap (OSM). However, GM/OSM usage requires the QtWebKit library which can only be part of BNC builds from shared libraries. Using a shared library BNC build requires that you first install your own shared Qt library. The 'README.txt' file which comes with the BNC source code describes how to install Qt on Windows, Linux and Mac systems.
BNC provides context-sensitive help (What's This) related to specific objects. It furthermore comes with the here presented documentation, available as part of the software and as a PDF file. Responsible for online and offline documentation, example configurations (and till February 2014 the overall BNC policy concept) is Dr. Georg Weber [georg.weber@bkg.bund.de].
BNC was designed to serve the following purposes:Retrieve real-time GNSS data streams available through Ntrip transport protocol;
Retrieve real-time GNSS data streams via TCP directly from an IP address without using the Ntrip transport protocol;
Retrieve real-time GNSS data streams from a local UDP or serial port without using the Ntrip transport protocol;
Plot stream distribut
