    1238 This example block header tells you that 67 bytes were saved in the data block following this time stamp. The information in this block is encoded in RTCM Version 3 format, comes from mountpoint RTCM3EPH and was received at 18:05:29 UTC on 2010-08-03. BNC adds its own time stamps in order to allow the reconstruction of a recorded real-time situation.

    14521452<li>Signals with attribute 'C' enjoy the highest priority. If such a Version 3 observation becomes available, it is presented as RINEX Version 2 observation if that is the format you wish to see. Observations with other attributes are being ignored.</li>

    1848 <li>When converting <u>RINEX Version 2 to Version 3</u> Observation files, the tracking mode or channel information in the (last character out of the three characters) observation code is left blank if unknown. This is a compromise, knowing that it is not in accordance with the RINEX Version 3 documentation.</li>

    3446 Specifying 'no for 'Wait for clock corr.' means that BNC processes each epoch of data immediately after its arrival using satellite clock corrections available at that time. A non-zero value means that epochs of data are buffered and the processing of each epoch is postponed till satellite clock corrections not older than 'Wait for clock corr.' seconds are available. Specifying a value of half the update rate of the clock corrections (e.g. 5 sec) may be appropriate. Note that this causes an additional delay of the PPP solutions in the amount of half of the update rate.

    3541 BNC allows processing several orbit and clock correction streams in real-time to produce, encode, upload and save a combination of Broadcast Corrections from various providers. All corrections must refer to satellite Antenna Phase Centers (APC). It is so far only the satellite clock corrections which are combined while orbit corrections in the combination product as well as the product update rates are just taken over from one of the incoming Broadcast Correction streams. Combining only clock corrections using a fixed orbit reference imposes the akward potential to introduce some analysis inconsistencies. We may therefore eventually consider improvements on this approach. The clock combination can be based either on a plain 'Single-Epoch' or on a Kalman 'Filter' approach.

    4158 The 'Logging Canvas' above the bottom menu bar on the main window labeled 'Log', 'Throughput', 'Lacenty', and 'PPP Plot' provides control of BNC's activities. Tabs are available for continuously showing logfile content, a plot controlling the bandwidth consumption, for a plot showing stream latencies, and for time series plots of PPP results.
