-6.3. Configuration Example
+6.3. Configuration Examples
+
+BNC comes with a number of configuration examples which can be used on all operating systems. There are two ways to start BNC using one of these files:
+
+- On graphical systems you may use the computer mouse to "drag" a configuration file icon and "drop" it on top of BNC's program icon.
+
+- On non-graphical systems you may start BNC using a command line with the following option for a configuration file (example for Windows systems):
bnc.exe --conf
+
+
+Presented example configuration files contain a user ID 'user' and a password 'pass' for accessing streams from various Ntrip broadcasters. Replace these account details by a the personal user ID and password you receive following an online registration through http://register.rtcm-ntrip.org.
+
+
+Note that the account for an Ntrip broadcaster is usually limited to pulling a certain maximum number of streams at the same time. As running some of the example configurations requires pulling several streams, it is suggested to make sure that you don't exceed your account's limits.
+
+
+Make also sure that directories which are part of the example configurations exist on your system or adjust the affected configuration according to your needs.
+
+
+Some BNC options require Antenna Phase Center variations as made available from IGS through so-called ANTEX files in directory 'ftp://igs.org/pub/station/general'. An example ANTEX file is also part of the BNC package for convenience.
+
+
+The example configurations assume that no proxy protects your host. Should a proxy be operated in front of BNC then you need to introduce its IP and port in the 'Network' tab.
+
+
+
+- File 'RinexObs.bnc'
+The purpose of this configuration is to convert RTCM streams to RINEX observation files. The configuration pulls streams from several Ntrip broadcasters using differen Ntrip versions and generate 1sec/15min RINEX version 3 observation files. See http://igs.bkg.bund.de/ntrip/observations for observation stream resources.
+
+
+- File 'RinexEpn.bnc'
+The purpose of this configuration if to convert RTCM streams to RINEX navigation files. The configuration pulls an RTCMv3 stream carrying broadcast ephemeris coming from the real-time EUREF and IGS network. It saves hourly RINEX version 3 navigation files. See http://igs.bkg.bund.de/ntrip/ephemeris for further real-time broadcast ephemeris resources.
+
+
+- File 'SSR.bnc'
+The purpose of this configuration is to save broadcast ephemeris corrections from RTCM SSR messages in a plain ASCII format as hourl files. See http://igs.bkg.bund.de/ntrip/orbits for further real-time IGS or EUREF orbit/clock products.
+
+
+- File 'RinexConcat.bnc'
+The purpose of this configuration is to concatenate RINEX version 3 files to produce a concatenated file and edit the marker name in the file header. The sampling rate is set to 30 seconds. See section 'RINEX Editing & QC' in the documentation for examples on how to call BNC from command line in 'no window' mode for RINEX file editing, concatenation and quality checks.
+
+
+- File 'RTK.bnc'
+The purpose of this configuration is to feed a serial connected receiver with observations from a reference station for conventional RTK. The stream is scanned for RTCM messages. Message type numbers and latencies of incoming observation are reported in BNC's logfile.
+
+
+- File 'FeedEngine.bnc'
+The purpose of this configuration is to feed a real-time GNSS engine with observations from a number of remote reference stations. The configuration pulls streams provided in various formats from different Ntrip broadcasters. Incoming observations are decoded, synchronized and output through a local IP port and saved into a file. Failure and recovery thresholds are specified to inform about outages.
+
+
+- File 'PPP.bnc'
+The purpose of this configuration is Precise Point Positioning from observations of a rover receiver. The configuration reads RTCMv3 observations, a stream of orbit and clock correctors and a broadcast ephemeris stream. Positions are saved in the logfile.
+
+
+- File 'QuickStartPPP.bnc'
+The purpose of this configuration is Precise Point Positioning in QuickStart mode from observations of a static receiver with precisely known position. The configuration reads RTCMv3 observations, orbit and clock correctors and a broadcast ephemeris stream. Positions are saved in NMEA format on disc and output through IP port for real-time visualization with tools like RTKNAVI.
+
+
+- File 'PPPPostProc.bnc
+The purpose of this configuration is Precise Point Positioning in Post Processing mode. BNC reads a RINEX observation and a RINEX v3 navigation files and a broadcast corrections files. PPP processing otions are set in support of the QuickStart mode. The output is saved in a specific post processing logfile and contains the coordinates derived over time following the implemented PPP filter algorithm.
+
+
+- File 'Sp3PPP.bnc'
+The purpose of this configuration is to produce SP3 files from a broadcast broadcast ephemeris stream and a stream carrying broadcast corrections. The single broadcast corrections stream is formally introduced in BNC's combination option for the reason of producing the SP3 file. Pulling in addition observations from a reference station with precisely know coordinates allows a continuous quality check of the broadcast corrections through observing coordinate displacements from an 'INTERNAL' PPP solution.
+
+
+- File 'Sp3ETRF2000PPP.bnc'
+This configuration equals the 'SP3PPP.bnc' configuration. However, it pulls the broadcast corrections stream 'EUREF01' which is refered to ETRF2000. Hence the SP3 file contains orbits refering to ETRF2000 and the 'INTERNAL' PPP solutions is compared to ETRF2000 coordinates.
+
+
+- File 'Upload.bnc'
+The purpose of this configuration is to upload orbits and clocks coming from a real-time GNSS engine to an Ntrip broadcaster. For that the configuration reads precise orbits and clocks in RTNET format. It also reads a stream carrying broadcast ephemeris. BNC converts the orbits and clocks into broadcast corrections and encodes them in RTCMv3 SSR messages messages to uploads them to an Ntrip broadcaster. The broadcast corrections stream is refered to satellite Center of Mass (CoM) and IGS08. Orbits are saved on disk in SP3 format and clocks in clock RINEX format.
+
+
+- File 'UploadPPP.bnc'
+This configuration equals the 'Upload.bnc' configuration. However, the broadcast ephemeris corrections are in addition used for an 'INTERNAL' PPP soltution based on observations from a static reference station with known precise coordinates. This allows a continuous quality ckeck of the broadcast ephemeris corrections through observing coordinate displacements.
+
+
+- File 'Combi.bnc'
+The purpose of this configuration is to pulls several streams carrying broadcast corrections and a broadcast ephemeris stream from an Ntrip broadcaster to produce a combined broadcast corrections stream. BNC encodes the combination product in RTCMv3 SSR messages and uploads it to an Ntrip broadcaster. The broadcast corrections stream is not refered to satellite Center of Mass (CoM). It is refered to IGS08. Orbits are saved in SP3 format and clocks in clock RINEX format.
+
+
+- File 'CombiPPP.bnc'
+This configuration equals the 'Combi.bnc' configuration. However, the combined broadcast ephemeris corrections are in addition used for an 'INTERNAL' PPP solutions based on observations from a static reference station with known precise coordinates. This allows a continuous quality check of the combination product through observing coordinate displacements.
+
+
+- File 'UploadEph.bnc'
+The purpose of this configuration is to pull a number of streams from reference stations to take out contained broadcast ephemeris messages. These are encoded then in a specific RTCMv3 stream which only provides broadcast ephemeris with an update rate of 5 seconds.
+
+
+
