r2443 r2444 62 62 63 63 <p> 64 Fig. 1 shows a flow chart of BNC connected to a GNSS receiver via serial or TCP communication link. The purpose could i.e. be PPP or conversion of RTCM streams to RINEX files. Fig. 2 shows a flow chart of BNC feeding a real-time GNSS engine. The engine then estimates satellite orbit and clock correctors. The 'BKG Ntrip Server' (BNS) is used in this scenario to encode correctors to RTCMv3. 64 Fig. 1 shows a flow chart of BNC connected to a GNSS receiver via serial or TCP communication link for the pupose of Precise Point Positioning. Fig. 2 shows the conversion of RTCM streams to RINEX batches. Fig. 3 shows a flow chart of BNC feeding a real-time GNSS engine. The engine then estimates satellite orbit and clock correctors.

Pay attention to data fields 'format' and 'format-details'. Keep in mind that BNC can only decode and convert streams that come in RTCM Version 2.x, RTCM Version 3.x, or RTIGS format. RTCM Version 2.x streams must contain message types 18 and 19 or 20 and 21 while RTCM Version 3.x streams must contain GPS or SBAS message types 1002 or 1004 and may contain GLONASS message types 1010 or 1012, see data field 'format-details' for available message types and their repetition rates in brackets. Note that in order to produce RINEX Navigation files RTCM Version 3.x streams containing message types 1019 (GPS) and 1020 (GLONASS) are required. Select your streams line by line, use +Shift and +Ctrl when necessary. Fig. 9provides an example source-table.1234 Use the 'Get Table' button to download the source-table from the NTRIP broadcaster.
