    571588BNC can be used in different contexts with varying data flows. Typical real-time communication follows the Ntrip protocol
    572 over TCP/IP (probably via SSL), RTSP/RTP or UDP, plain TCP/IP protocol, or serial communication links.
    573 Stream content could be observations, ephemeris, satellite orbit/clock products or NMEA sentences.

    576593The first of the following figures shows a flow chart of BNC connected to a GNSS receiver providing observations via
    577 serial or TCP communication link for the purpose of Precise Point Positioning. The second figure shows the conversion
    578 of RTCM streams to RINEX files. The third figure shows a flow chart of BNC feeding a real-time GNSS engine which
    579 estimates precise orbits and clocks. BNC is used in this scenario to encode correctors to RTCM Version 3 and upload
    580 them to an Ntrip Broadcaster. The fourth figure shows BNC combining several Broadcast Correction streams to
    581 disseminate the combination product while saving results in SP3 and Clock RINEX files.
