There is no reason a GPS has to be the position input device for  
APRS.  There is certainly no reason it has to be a cheap GPS.

Clearly someone has use for it, or we wouldn't be discussing it.

Certainly *I* have had use for more accurate positions than APRS  
normally gives, but still within the accuracy of a GPS receiver.  I  
would like to be able to transmit a position of, say, a Geocache  
object and have it display (accurately) on my GPS in my vehicle,  
rather than just show up "nearby".  Now maybe people in other hobbies  
wouldn't care about that - that's fine, but having this capability  
isn't a bad thing, if, like Bob keeps trying to explain, it's done in  
a way that doesn't break everything that can't understand it.

It's definitely got it's uses, although, I agree, the normal accuracy  
and resolution of APRS is fine for 99% of situations, and certainly  
any moving vehicle.
