     4258BNC may upload the Broadcast Correction streams using different Formats. Supported are:
     4259<p>
     4260<ul>
     4261  <li>IGS-SSR which was developed within the IGS Real-Time Working Group, and</li>
     4262  <li>RTCM-SSR which stands for the standardized and proposed SSR Messages which are developed within the RTCM SC-104 Working Group State Space Representation.</li>

    42804267<p>
    42814268BNC allows to either refer Broadcast Corrections to the satellite's Center of Mass (CoM) or to the satellite's Antenna Phase Center (APC). By default, corrections refer to APC. Tick 'Center of Mass' to refer uploaded corrections to CoM.
    42824269</p>

    42854272<p>Specify a path for saving the generated orbit corrections as SP3 orbit files. If the specified directory does not exist, BNC will not create SP3 orbit files. The following is a path example for a Linux system:

    43134300<p>
    43144301The clock corrections generated by BNC for upload can be logged in Clock RINEX format. The file naming follows the RINEX convention.

    43294316<p>
    43304317When applying Broadcast Ephemeris corrections in a PPP algorithm or in a combination of several correction streams, it is important for the client software to receive information on the continuity of discontinuity of the stream contents. Here you can specify three ID's to describe the contents of your Broadcast Ephemeris correction stream when it is uploaded.

    43394326<p>
    43404327Select the length of Clock RINEX files and SP3 Orbit files. The default value is 1 day.

     4330<p><h4 id="upclksmpl">2.15.10 Sampling</h4></p>
    43444331<p>BNC requires an orbit corrections sampling interval for the stream to be uploaded and sampling intervals for SP3 and Clock RINEX files. The outgoing stream's clock correction sampling interval follows that of incoming corrections and is therefore nothing to be specified here.</p>
    43454332
    4346 <p><h4 id="upclkorb">2.15.9.1 Orbits (Orb) - mandatory if 'Upload Table' entries specified</h4></p>
     4333<p><h4 id="upclkorb">2.15.10.1 Orbits (Orb) - mandatory if 'Upload Table' entries specified</h4></p>
    43474334<p>Select the stream's orbit correction sampling interval in seconds. A value of 60 sec may be appropriate.</p>
    43484335<p> A value of zero '0' tells BNC to upload all orbit correction samples coming in from the real-time GNSS engine along with the clock correction samples to produce combined orbit and clock corrections to Broadcast Ephemeris (1060 for GPS, 1066 for GLONASS).
     
    43754362<br>
    43764363Note that only when specifying a value of zero '0' (default) for 'Sampling Orb', BNC produces <b>combined</b> orbit and clock correction messages.
    4377 <p><h4 id="upclksp3">2.15.9.2 SP3 - mandatory if 'SP3 File' is specified</h4></p>
     4364<p><h4 id="upclksp3">2.15.10.2 SP3 - mandatory if 'SP3 File' is specified</h4></p>
    43784365<p>Select the SP3 orbit file sampling interval in minutes. A value of 15 min may be appropriate. A value of zero '0' tells BNC to store all available samples into SP3 orbit files.</p>
    43794366
    4380 <p><h4 id="upclkrnx">2.15.9.3 RINEX (RNX) - mandatory if 'RNX File' is specified</h4></p>
     4367<p><h4 id="upclkrnx">2.15.10.3 RINEX (RNX) - mandatory if 'RNX File' is specified</h4></p>
    43814368<p>Select the Clock RINEX file sampling interval in seconds. A value of 10 sec may be appropriate. A value of zero '0' tells BNC to store all available samples into Clock RINEX files.</p>
    43824369
    4383 <p><h4 id="upcustom">2.15.10 Custom Trafo - optional if 'Upload Table' entries specified</h4></p>
     4370<p><h4 id="upcustom">2.15.11 Custom Trafo - optional if 'Upload Table' entries specified</h4></p>
    43844371<p>Hit 'Custom Trafo' to specify your own 14 parameter Helmert Transformation instead of selecting a predefined transformation through 'System' button.</p>
    43854372
    4386 <p><h4 id="upantex">2.15.11 ANTEX File - mandatory if 'SP3 File' is specified</h4></p>
     4373<p><h4 id="upantex">2.15.12 ANTEX File - mandatory if 'SP3 File' is specified</h4></p>
    43874374<p>
    43884375IGS provides a file containing absolute phase center variations for GNSS satellite and receiver antennas in ANTEX format. Entering the full path to such an ANTEX file is required here for referring the SP3 file content to the satellite's Center of Mass (CoM). If you do not specify an ANTEX file, the SP3 file will contain orbit information which is referred to Antenna Phase Center (APC) instead of CoM.

    4412 Note that Broadcast Ephemeris received in real-time have a system specific period of validity in BNC which is defined in accordance with the update rates and validity intervals of the navigation messages.

    44134400<ul>
    44144401<li>GPS ephemeris will be interpreted as outdated and ignored when older than 4 hours.</li>
     
    44254412<p>
    44264413Furthermore, received Broadcast Ephemeris parameters pass through a plausibility check in BNC which allows to ignore incorrect ephemeris data when necessary, leaving a note 'WRONG EPHEMERIS' in the logfile.
    4427 Unhealthy ephemerides will be not excluded. A note 'UNHEALTHY EPHEMERIS' will be added in the logfile.
     4414Unhealthy Broadcast Ephemeris will not be excluded. A note 'UNHEALTHY EPHEMERIS' will be added in the logfile.

    4439 <p>
    4440 BNC uploads a stream to the Ntrip Broadcaster by referring it to a dedicated mountpoint that has been set by its operator. Specify the mountpoint based on the details you received for your stream from the operator. It is often a 4-character ID (capital letters) plus an integer number.</p>
    4441 <p>The stream upload follows Ntrip Version 1 and may be protected through an upload 'Password'. Enter the password you received from the Ntrip Broadcaster operator along with the mountpoint.</p>

    4444 <p><h4 id="brdcsmpl">2.16.3 Sampling - mandatory if 'Host' is set</h4></p>

     4426<p>
     4427BNC uploads a stream to the Ntrip Broadcaster by referring it to a dedicated mountpoint that has been set by its operator. Specify the mountpoint based on the details you received for your stream from the operator. It is often a 9-character ID (capital letters) plus an integer number.</p>
     4428<p>For stream upload the Ntrip Version can be chosen. An Ntrip version 1 upload is protected through an upload 'Password' only. For an Ntrip Version 2 upload an upload 'User' is required in addition. Enter the user name and the password you received from the Ntrip Broadcaster operator along with the mountpoint.</p>
     4429</p>
     4430
     4431<p><h4 id="brdcsys">2.16.3 Satellite System - mandatory if 'Host' is set</h4></p>
     4432Specify the satellite system(s) that shall be part of the uploaded stream (e.g. G for GPS or GRE for GPS+GLONASS+Galileo, or ALL).

     4434<p><h4 id="brdcsmpl">2.16.4 Sampling - mandatory if 'Host' is set</h4></p>
    44454435Select the Broadcast Ephemeris repetition interval in seconds. Default is '5', meaning that a complete set of Broadcast Ephemeris is uploaded every 5 seconds.
