The stream is scanned for RTCM messages. Message type numbers and latencies of incoming observation are reported in BNC's logfile. 2920 </li><br> 2921 2922 <li>File 'FeedEngine.bnc'<br> 2923 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. 2924 </li><br> 2925 2926 <li>File 'PPP.bnc'<br> 2927 The purpose of this configuration is Precise Point Positioning from observations of a rover receiver. The configuration reads RTCM Version 3 observations, a stream of Broadcast Corrections and a Broadcast Ephemeris stream. Positions are saved in the logfile. 2928 </li><br> 2929 2930 <li>File 'PPPQuickStart.bnc'<br> 2931 The purpose of this configuration is Precise Point Positioning in Quick-Start mode from observations of a static receiver with precisely known position. The configuration reads RTCM Version 3 observations, Broadcast Corrections and a Broadcast Ephemeris stream. Positions are saved in NMEA format on disc. Positions are also output through IP port for real-time visualization with tools like RTKPLOT. 2932 </li><br> 2933 2934 <li>File 'PPPPostProc.bnc'<br> 2935 The purpose of this configuration is Precise Point Positioning in Post 2936 </li><br> 2937 Processing mode. BNC reads a RINEX Observation and a RINEX Version 3 Navigation files and a Broadcast Corrections files. PPP processing otions are set to support the Quick-Start mode. The output is saved in a specific Post Processing logfile and contains the coordinates derived over time following the implemented PPP filter algorithm. 2938 2939 <li>File 'SPPQuickStartGal.bnc'<br> 2940 The purpose of this configuration is Single Point Positioning in Quick-Start mode from observations of a static receiver with precisely known position. The configuration uses GPS, GLONASS and Galileo observertions and a Broadcast Ephemeris stream. 2941 </li><br> 2942 2943 <li>File 'Sp3.bnc'<br> 2944 The purpose of this configuraiton is to produce SP3 files from a Broadcast Ephemeris stream and a Broadcast Corrections stream. Note that this requires an ANTEX file because SP3 file contents should be referred to CoM. 2945 </li><br> 2946 2947 <li>File 'Sp3ETRF2000PPP.bnc'<br> 2948 The purpose of this configuration is to produce SP3 files from a Broadcast Ephemeris stream and a stream carrying ETRF2000 Broadcast Corrections. The Broadcast Corrections stream is formally introduced in BNC's 'Combine Corrections' table. This leads to an SP3 file containing orbits referred also to ETRF2000. Pulling in addition observations from a reference station at precisely known ETRF2000 position allows to compare an 'INTERNAL' PPP solution with ETRF2000 reference coordinates. 2949 </li><br> 2950 2951 <li>File 'Upload.bnc'<br> 2952 The purpose of this configuration is to upload orbits and clocks 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 RTCM Version 3 SSR messages to uploads them to an Ntrip Broadcaster. The Broadcast Corrections stream is referred to satellite Antenna Phase Center (APC) and IGS08. Orbits are saved on disk in SP3 format and clocks in Clock RINEX format. 2953 </li><br> 2954 2955 <li>File 'UploadPPP.bnc'<br> 2956 This configuration equals the 'Upload.bnc' configuration. However, the Broadcast 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 check of the Broadcast Corrections through observing coordinate displacements. 2957 </li><br> 2958 2959 <li>File 'Combi.bnc'<br> 2960 The purpose of this configuration is to pull 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 RTCM Version 3 SSR messages and uploads that to an Ntrip Broadcaster. The Broadcast Corrections stream is not referred to satellite Center of Mass (CoM). It is referred to IGS08. Orbits are saved in SP3 format and clocks in Clock RINEX format. 2961 </li><br> 2962 2963 <li>File 'CombiPPP.bnc'<br> 2964 This configuration equals the 'Combi.bnc' configuration. However, the combined Broadcast 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. 2965 </li><br> 2966 2967 <li>File 'UploadEph.bnc'<br> 2968 The purpose of this configuration is to pull a number of streams from reference stations to get hold of contained Broadcast Ephemeris messages. These are encoded then in a RTCM Version 3 stream which only provides Broadcast Ephemeris with an update rate of 5 seconds. 2869 2969 </li> 2870 <br> 2871 <li>File 'RinexEph.bnc'<br> 2872 The purpose of this configuration is to convert RTCM streams to RINEX Navigation files.
