Thanks, Florian.

Yes, I had understood that setting it should be a permanent thing (the 
GPS has a large capacitor battery), but that doesn't seem to be 
happening.  I'm not doing anything to disable it, so I'm wondering 
whether /something/ is causing a reset at boot time.  Could gpsd be 
doing this?

My Linux expertise doesn't stretch do writing the appropriate udev rule, 
but I have at least heard of "udev".  Could you possibly point me to the 
appropriate tutorial for this, perhaps one with an example?

I've been testing simply with "cgps -s" where the GA is absent 
initially, but present once the enable command is sent.  Yes, one of the 
ubxtool (very helpful, Gary) commands does say whether the constellation 
is enabled and/or active (from memory), but cgps produces a more 
readable result more quickly!

Cheers,
David
