[FOSS-GPS] BINR to RTCM

[David Kelley]

Frankly I can not see the issue from what you have posted, or why you 
are getting these two SVs rejected.  It would help if you could post 
your settings (the *.ini file) as we can see what is odd, but before  
you do so be sure and remove the private passwords for your casters etc 
from it.  [The RTKLIB tool store the user and the password together, so 
seek for lines in the format =user:password at theURL:thePORT/theMountPoint:]

Back to the original problem of the thread, I defer to arwooldridge

to describe it in more dept but:  We have conclusively seen over the 
last month that that same stream of data from from a uBlox device 
performed noticeably poorly when passed from the Stream Convert 
(converting the native format to RTCM) and into RTKNavi, then the same 
set of data passed into the RTKNavi tool directly.  We believe the same 
thing occurs with the BINR stream but at my office we can not make the 
NVS chips work with RTKLIB yet.  These two processing paths should be 
identical for all practical purposes, with the same net result.

The core issue seems to be minor differences in the way the proprietary 
encoding is treated (vs the RTCM 1004 messages) between the two tools.  
I find no actual errors anywhere in RTKLIB about this, but I suspect 
that there are difference in the how the cycle clips are detected and 
reported in this.  I remain annoyed that I can not yet pin this down and 
will keep at it.  One can reproduce the problem by running  multiple 
copies RTKLIB with the two different settings, or by an L-band replay 
with a tool like the LabSat3.  In either event, the percentage of time 
spent in a fixed mode is sharply reduced when the stream convert tool is 
used regardless of the baseline distance.
