Are GPSDdata items correct?

Nice to meet you
I’m studying trying to remodel an Autosteer.ino sketch
Where can I find the latest PGNCodes (for packets sent to and received from AOG)?
Probably correct, but different from the display of GPSdata, I am confused.1102

from Japan

When you say ‘PGNCodes’ - do you mean the ‘parameter group numbers’ that are talked about here:

I found some pgn.xlsx files in thecombineforum.com.

Specifically, is the lower right frame of “GPS Data” the data from AutoSteer (port 5577) starting with the 0x7FFD header ?
