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

    120122<p><h4>B - 4.1 Wait for Full Epoch</h4></p>
    121123<p>
    122 When feeding a real-time GNSS engine waiting for input epoch by epoch, BNC ignores whatever is received latern then 'Wait for full epoch' seconds. A value of 2 to 5 seconds may be an appropriate choise for that, depending on the delay you can accept for your real-time product. Note that 'Wait for full epoch' does not influence the RINEX file contents. Observations coming in later than 'Wait for full epoch' will still be included there.

    132134<p><h4>B - 4.3 Port for Binary Output</h4></p>
    133135<p>
    134 BNC outputs synchronized observations in a binary format through an IP port with the following format: ..... Souce code of an example program 'test_bnc.cpp' that reads the binary data to feed real-time GNSS applications is available.

    135137</p>
    136138
     
    140142Observations are converted to RINEX format version 2.1. Note that RINEX file names are derived by BNC from the first 4 characters of the corresponding mountpoint (4Char Station ID). Thus, retrieving data from mounpoints FFMJ1 and KARL0 leads to RINEX files named FFMJ*.* and KARL*.*.</p>
    141143<p>
    142 In case you retrieve straeams that show mountpoints with an identical 4Char Station ID, the full mountpoint string will become part of the RINEX file name. Example: When simultaneously retrieving mountpoints FFMJ1 and FFMJ3, there RINEX file names will be FFMJ*_1.* and FFMJ*_3.*.
     144In case you retrieve streams that show mountpoints with an identical 4Char Station ID, the full mountpoint string will become part of the RINEX file name. Example: When simultaneously retrieving mountpoints FFMJ1 and FFMJ3, there RINEX file names will be FFMJ*_1.* and FFMJ*_3.*.

    152154<p><h4>B - 5.2 RINEX Script</h4></p>
    153155<p>
    154 Whenever a RINEX file is generated, you may like to compress, copy, or upload it immediately. For that you enter the full path of a script or bach file carrying out these operations. The RINEX file name will be passed to the script as a command line parameter. Note the following example for a 'RINEX Script' file: ${HOME}/upload_script

    181 Concerning RTCM Version 3 streams: If the ambiguity field is not set, the output will be no valid RINEX. All values will be stored modulo 299792.458. A COMMENT line will tell you, when this happens. It would be necessary to approximately calculate the range to fix the ambiguity (needing ephemeris/alamanac and easy positioning algorithm).

    223 To delete a stream shown under 'Mountpoints' in BNC's main windows select it by mouse click and hit 'Delete Mountpoints'. You may tag more than one stream for simultaneous delition through using +Shift and +Strg.</p>
    224 <p>
    225 BNC automatically selectes the decoder for a stream based on the 'format' and 'format-details' given in the sourcetable. It may happen that you need to overrule this decoder selection because of sourcetable setup deficiencies. Therefore BNC allows to edit the decoder part for each stream shown under 'Mountpoints'. Accepted decoder strings are are 'RTCM 2.x', 'RTCM 3', and 'RTIGS'.

    305 NTRIP is an RTCM standard designed for disseminating differential correction data (e.g in the RTCM-104 format) or otherkinds of GNSS streaming data to stationary or mobile users over the Internet, allowing simultaneous PC, Laptop, PDA, orreceiver connections to a broadcasting host. NTRIP supports wireless Internet access through Mobile IP Networks like GSM, GPRS, EDGE, or UMTS.
