r2444 r2445 64 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. The 'BKG Ntrip Server' (BNS) is used in this scenario to encode correctors to RTCMv3. 65 65 </p> 66 <p><img src=" :/bnchelp/screenshot10.png"/></p>66 <p><img src="IMG/screenshot10.png"/></p> 67 67 <p><u>Fig. 1:</u> BNC connected to a GNSS receiver for Precise Point Positioning.</p> 68 68 69 69 <p> 70 70 </p> 71 <p><img src=" :/bnchelp/screenshot01.png"/></p>71 <p><img src="IMG/screenshot01.png"/></p> 72 72 <p><u>Fig. 2:</u> BNC converting RTCM streams to RINEX batches.</p> 73 73 74 74 <p> 75 75 </p> 76 <p><img src=" :/bnchelp/screenshot02.png"/></p>76 <p><img src="IMG/screenshot02.png"/></p> 77 77 <p><u>Fig. 3:</u> BNC feeding a real-time GNSS engine.</p> 78 78 … … 96 96 This section describes BNC's top menu bar, its processing options, the 'Streams' and 'Log' sections, and the bottom menu bar, see Fig. 4. 97 97 </p> 98 <p><img src=" :/bnchelp/screenshot09.png"/></p>98 <p><img src="IMG/screenshot09.png"/></p> 99 99 <p><u>Fig. 4:</u> Sections on BNC's main window.</p> 100 100 … … 978 978 Fig. 5. provides the screenshot of an example PPP session with BNC. 979 979 </p> 980 <p><img src=" :/bnchelp/screenshot03.png"/></p>980 <p><img src="IMG/screenshot03.png"/></p> 981 981 <p><u>Fig. 5:</u> Precise Point Positioning (PPP) with BNC.</p> 982 982 … … 1172 1172 <p><a name="throughput"><h4>3.13.2 Throughput</h4></p> 1173 1173 <p> 1174 The bandwidth consumption per stream is shown in the 'Throughput' tab in bits per second (bps) or kilo bits per second (kbps).
