Can you please send me a file of the original and your parsed and filtered output and I will run them through a couple of different RTCM parserswhich we use and see what gives.  I presume in all this you have the right RTCM 104 specs to guide you as well.

Regards, David Kelley

Hello,

Below is an example of the one of the messages in the printed data output
from the OEM receiver:



My script simply reads this formatted data, and parses the hex into a string
that is sent to the receiver.  For example, it would be something along the
lines of:


I attempted just typing out an entire packet and sending that manually, but
have also confirmed that my script does parse it correctly by viewing the
hex input on the screen you showed me. 

My receiver model is the OEMV-3:
http://www.novatel.com/products/gnss-receivers/oem-receiver-boards/oemv-receivers/oemv-3/

I have viewed the firmware quick-reference manual:
http://www.novatel.com/support/info/documents/580
It does indicate that the RAWWAASFRAME is formatted like the log output
shows, so I'm really not certain where I'm going wrong, unless the log data
is for some reason entirely different from the data that RTKlib is looking
for...!

Thanks for your help.
