Hi James,

thanks for this hint. For you, Gary and others 2 files attached (gzip'd)

Kind regards

When I start
xgps -u m localhost:gpsd:/dev/serial0 &
I don't get any information on column "qual" and "prRes".

You might need to wait for a feature in the u-blox driver.

A raw capture from the device will probably be useful in Garys
hands.

Probably the way to manage that would be to park your receiver out
in the boonies by itself for a while, because of law lemurs.

I suspect the output of gpsdebuginfo would be less useful,
especially to me.

Do I need to prepare the ZED-X20P with some settings ?
Actually this is not necessary when I use any other u-blox's

Maybe if you can convince it to emit those sentences in a lower
protocol version.
