John:
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:
http://www.gpstk.org/bin/view/Documentation/NovaRinexManual
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

David,
(somehow the last message was put in a new thread, returning it back to

Could you perhaps link me to one of these 3rd party tools or open toolkits?
I'm new to working with these GPS receivers so I am quite unfamiliar with
everything!
Thanks,
John

I am puzzled, you should at least be able to use one of 3rd party tools,
another open toolkit, or the vendors tools to prove this data stream can
be decoded. There are many tools out there for Novatel. Once that works,
I would then perhaps think the parser step can be of value. If you send a
snapshot of what you are getting I can take a look, or ask a Novatel
person next week at ION, but your results seem odd to me. In my limited
experience people often presume a msg or data product in the stream that
is not in fact there, so I have learned to expend the effort to confirm
that first.
