I dropped the Tria GPS into a REF-0 and launched SatStat to view the status screen. To my slight surprise, nearly everything was populated correctly. I had to make some minor adjustments, but the new Oncore message formatting routine is a success. Here's a screen capture of SatStat for the REF-0 with the Tria GPS:
The SV info is little wonky. Partly that is because I have to adapt satellite info for a 16 channel receiver to 8- and 12-channel messages. I plan to do some more sorting to ensure that the top 12 SVs that the U-blox has acquired appear in the status screen of the GPSDO.
With my message formatting routine working, I am closer to the end goal of full Oncore compatibility. I now need to write some code to allow the GPSDO to send commands to the Tria GPS and configure it. Once that is done, I will be able to make a REF-1 lock up using the new GPS. That will be exciting.
Thanks for reading!
