I have an Adafruit Ultimate GPS using a PA6H module (datasheet) with PTMK command packets (command set sheet). I have it connected to my PC via Arduino and want to be able to read the SBAS data (specifically EGNOS as I am in the UK) that the module receives- the module returns acknowledgement when the SBAS enable command is sent, but I can't work out how I'd actually get at the data it's receiving. Specifically, I'm after the pseudorange corrections. I appreciate that this is Arduino Stackexchange and not GIS stackexchange, but this felt like a fairly appropriate place to post the question.
Any help is appreciated!
