    5446Furthermore, BNC allows to by-pass its decoding and conversion algorithms, leave whatever is received untouched and save it in files.

    56 <p><b>Resources</b><br>
    57 BNC needs access to the Internet with a minimum of about 2 to 6 kbits/sec per stream depending on the stream format. You need to make sure that you have always the necessary bandwidth available. BNC has the capacity to retrieve hundreds of GNSS data streams simultaneously. Please be aware that it is a powerful tool that may generate a heavy workload on the NTRIP broadcaster side depending on the number of streams it requests. We suggest to limited the number of streams where possible to avoid unnecessary workload.

    137133<p>
    138134You may like to run BNC in a Local Area Network (LAN). LANs are often protected by a proxy server. Enter your proxy server IP and port number in case one is operated in front of BNC. If you don't know the IP and port of your proxy server, check out the proxy server settings of your Internet browser or ask your network administrator.</p>
    139135<p>
    140 Note that IP streaming may generally be denied in a LAN. In such a case you need to ask your network administrator for an appropriate modification of his security policy or for the installation of a TCP relay to involved NTRIP broadcasters. If that doesn't work out, run BNC outside your LAN on a host that is connected to the Internet through an Internet Service Provider (ISP).

     139<p><a name="output"><h4>3.4. Synchronized Output</h4></p>
     140<p>
     141BNC lets you output synchronized observations (no ephemeris) from all stations and satellites epoch by epoch. This output is made available in a plain ASCII format and/or a binary format. The output comprises the following observations if available:</p>
    146142<p>
    147143StatID, SVPRN, GPSWeek, GPSWeeks, C1, C2, P1, P2, L1, L2, S1, S2, SNR1, SNR2
    148144</p>
    149145<p>
    150 Note that SNR stands for the signal-to-noise ratio S mapped to integer numbers 1 to 9. Note further that in case an observation is unavailable, its value is set to zero '0.000'.

    152 <p><a name="wait"><h4>B - 4.1 Wait for Full Epoch - optional</h4></p>
    153 <p>
    154 When feeding a real-time GNSS engine waiting for input epoch by epoch, BNC ignores whatever is received later than 'Wait for full epoch' seconds. A value of 3 to 5 seconds could be an appropriate choice for that, depending on the latency of the incoming streams and the delay you can accept for your real-time GNSS product. Default value for 'Wait for full epoch' is 1 second.

    170166BNC makes synchronized observations available in a binary format on your local host (IP 127.0.0.1) through an IP port. Enter an IP port number to activate this function. Default is an empty option field, meaning that no binary output is generated.</p>

    214210Observations will be converted to RINEX if they come in either RTCM Version 2.x, RTCM Version 3.x, or RTIGS format. BNC's RINEX Observation files generally contain C1, C2, P1, P2, L1, L2, S1, and S2 observations. In case an observation is unavailable, its value is set to zero '0.000'. Note that even if a RINEX Observation file does not contain GLONASS or SBAS data, the 'RINEX TYPE' field in the RINEX Observation file header may be set to 'M (MIXED)'.

    218214RINEX file names are derived by BNC from the first 4 characters of the corresponding mountpoint (4Char Station ID) while omitting the residual part of the mountpoint string. Thus, retrieving data from mountpoints FRANKFURT and WETTZELL leads to hourly RINEX Observation files named</p>

    249245Enter a path for saving the RINEX Observation files in a directory. If this directory does not exist, BNC will not create RINEX Observation files. Default value for 'RINEX directory' is an empty option field, meaning that streams are not converted to RINEX.

    259255Whenever a RINEX Observation file is saved, you may like to compress, copy or upload it immediately via FTP. For that you enter the full path of a script or batch file which is then called to carry out these operations. The RINEX Observation file path will be passed to the script as a command line parameter (%1 on Windows systems, $1 on Unix/Linux systems).

    280276Whenever BNC starts generating RINEX Observation files (and then once every day at midnight), it first tries to retrieve information needed for RINEX headers from so-called public RINEX header skeleton files which are derived from sitelogs. An HTTP link to a directory containing these skeleton files may be available through data field number 7 of the affected NET record in the source-table. See <u>http://www.epncb.oma.be:80/stations/log/skl/brus.skl</u> for an example for a public RINEX header skeleton file concerning the EPN station Brussels.

    331 When starting BNC, new RINEX Observation files are created by default. Probably existing files will be overwritten. However, it may be desirable to append observations (and ephemeris) to already existing RINEX files following a restart of BNC after an intentional 'Stop', a system crash or a crash of BNC. Hit 'Append files' to continue with already existing files and thus save what has been recorded so far.

    600 RTCM Version 3.x has been developed as a more efficient alternative to RTCM 2.x. Service providers and vendors have asked for a standard that would be more efficient, easy to use, and more easily adaptable to new situations. The main complaint was that the Version 2 parity scheme was wasteful of bandwidth. Another complaint was that the parity is not independent from word to word. Still another was that even with so many bits devoted to parity, the actual integrity of the message was not as high as it should be. Plus, 30-bit words are awkward to handle. The Version 3 standard is intended to correct these weaknesses.

    628637RTIGS stands for a data format and transport protocol for GPS observations. It was defined by the Real-Time IGS Working Group (RTIGS WG). Its definition is based on the SOC format. Every RTIGS record has one of the following numbers:

    681690The SOC format has been designed in July 1999 by the Jet Propulsion Laboratory (JPL) and the California Institute of Technology (CalTech) to transport 1Hz GPS data with minimal bandwidth over the open Internet. SOC follows the 'little-endian' byte order meaning that the low-order byte of a number is stored in memory at the lowest address, and the high-order byte at the highest address. Because the transport layer is UDP, the format does not include sync bits, a checksum, or cyclic redundancy checksum (CRC). SOC allows to transport the GPS observable CA, P1, P2, L1, and L2, efficiently compressed down to 14 bytes with 1 mm range resolution and 0.02 mm phase resolution. SOC contains epochs for cycle slips, a stand-alone time-tag per epoch, a minimum representation of the receiver's clock solution, 3 SNR numbers, a unique site id, a modulo 12 hour sequence number and flags for receiver type and GPS health. SOC's simple structure comprises an 8 byte header, a 9 byte overhead for timetag, number of gps, etc., plus 21 data bytes per gps.
