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. </div><div><br></div><div>Regards, David Kelley</div><br><br>-------- Original message --------<br>From: jtwork <taflan.work@gmail.com> <br>Date:09/03/2014 11:05 AM (GMT-08:00) <br>To: foss-gps@lists.osgeo.org <br>Subject: [Spam] Re: [FOSS-GPS] Using RTKLib with Novatel OEM device as base <br><br>David,<br><br>The message is the 'binary log' output for the data message in the Novatel<br>OEM format. The hex that it displays is supposedly a correct message, but I<br>just realized after somehow thinking there was no issue that rather than the<br>'AA4412' sync chars that are supposed to start off the message, every<br>message starts with '004412'. I'm not sure why this is, especially since<br>even in the Novatel documentation there is no mention of a replacement of 00<br>for AA, and the Novatel parser in the source code definitely uses 'AA4412'<br>as the sync chars. Perhaps there is some sort of strange header only for<br>the logs?
