[FOSS-GPS] [Spam] Re: Using RTKLib with Novatel OEM device as base

Did not NovAtel or the vendor you obtained your modules from provide 
such a thing?   In our shop we do not use their products, mostly due to 
simply being content with other devices (please note that they make 
great stuff), so I myself have never built a decoder for them.

But as you have noted, RTKLIB has one, as does gnsstk.  So does GIPSY if 
you are allowed to access it.  Those are more or less the top open 
toolkits. Keep in mind that the RTKCONV tool may still be you best bet 
for a simple GUI tool, off hand I do not know how to "turn up" the debug 
level there to get some helpful clues.  If anyone else does, please post.

A search for: 'novatel gps binary decoder' shows one I have heard other 
use, as well a some source code examples.

 From the University of Texas (Austin) group there is a tool at:

And I do not know if TEQC can also process it (it converts just about 
everything else)
A quick scan of the mail traffic suggests it does not, but this a tool 
to know about in any event.

I am concerned that the above tosses you into deeper waters than someone 
who simply want to 'use' GPS may care to be but offer it in the hope of 
doing some good.
Good Luck, David Kelley
