BKG Ntrip Client (BNC) 
The BKG Ntrip Client (BNC) is an Open Source multi-stream client program designed for a variety of real-time GNSS applications.
It was primarily designed for receiving data streams from any Ntrip supporting Broadcaster. The program handles the HTTP communication and transfers received GNSS data to a serial or IP port feeding networking software or a DGPS/RTK application. It can compute a real-time Precise Point Positioning (PPP) solution from RTCM streams or RINEX files. During the last years BNC has been enriched with RINEX quality and editing functions. You can run BNC with GUI as well as in batch processing mode.
