We're using bnc 2.12.2 to retrieve data from different casters (about ~250 different mountpoints) at a sample rate of 10 seconds. Every day at midnight we loss all the mountpoints data. It looks like there is some kind of problem with the time reference used by bnc in this case and therefore it discards all date with "Old epoch" messages (find attached full log).

In case it is useful for your, there seem to be two things also happening at the day change: configuration read (which is always done, even if the onTheFlyInterval is not set) and rinex files creation. Perhaps some of this tasks is blocking the others, which adds a delay bigger than the sample rate?

Thanks in advance, David Roma

Dear colleagues,

I would like to know how does the construction of BRDC work on BNC. BNC is configurated to save rinex navigation files (GPS and GLONASS separated)on a directory with an interval of 15min. When I start a stream (RTCM3.1 on TLSE1 station for example), BNC produce rinex navigation files, but some of them are empty or other one contains only GPS information. But when I scan the stream, I found 1019 and 1020 RTCM messages each 30s. Could you please explain us this behavior? does BNC take into account only one time the ephemeris of a PRN and wait a new generation of ephemeris to save it ?

Thank you for your answer. Best regards Gregory

Problem can be reproduced in the following way: 1) "Add Stream" -> "Caster" 2) Select arbitrary caster from combobox e.g. www.euref-ip.net 3) Ntrip Version -> 2s 4) Press "Get table" 5) Press "Close" 6) Trying to add another stream will cause program freezing.

It seems that setting Ntrip version to 2s is locking mutex in

t_irc bncTableDlg::getFullTable

which then can not be unlocked since function is still waiting for response from caster.

After pressing "Get table" (step 6) the widgets (caster combo box, user name line edit etc.) on the "Add Stream" dialog are still active which also seems not to be correct.

I've use two Linux versions: static build by BKG for Ubuntu 14 x64 and my port to Qt5 and built with newmat included in my distro. The problem exists on both.
