When I power my EM406 module I see the following message…
$PSRFTXT,WAAS Enable
…so I think it should be using WAAS. Is there any way to tell from the NMEA messages coming out that the module is actually using WAAS in its solution.
I was expecting to see the “Fix Quality” field in the $GPGGA message to change to something other than 1 (GPS fix), but it doesn’t.
