    7272The first of the following figures shows a flow chart of BNC connected to a GNSS receiver via serial or TCP communication link for the pupose of Precise Point Positioning. The second figure shows the conversion of RTCM streams to RINEX batches. The third figure 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.

    353353The screenshot below shows an example setup of BNC when converting streams to RINEX. Streams are coming in from various NTRIP broadcasters as well as via a plain UDP and a serial communication link. Decoder 'ZERO' has been selected for one stream to not convert its contents but save it in original format.

    1457 The following two screenshots show the the setup of BNC when combining corbit and clock correctors streams. It requires to specify options on tabs 'Combination', 'Broadcast Corrections' and 'PPP (2)', clarify following paragraphes. The example given here uses the combination product to simultaneously carry out a PPP solution with options shown in tab 'PPP (1)'.

     1457The following screenshots describe an example setup of BNC when combining orbit and clock correctors streams. Note that it requires to specify options at least under the three tabs 'Combination', 'Broadcast Corrections' and 'PPP (2)'. The example given here uses the combination product in addition to simultaneously carry out a PPP solution with options shown in tab 'PPP (1)' - which enables to monitor the quality of the combination product in the space domain.
