[Elecraft] Re: WWV DST

Actually, WWV and WWVB are not worldwide in range.  Military uses a system 
that is space based so they can see 12 satellites for a "fix" from anywhere 
on the globe they may need position.

But, there are effects to GPS signals if you are not using a 12 satellite 
solution, and thus, GPS quality at your receiver may depend on a number of 
factors.

Higher quality GPS solutions come from the differential methods pioneered by 
our university laboratory.  I am proud of my friends that developed the 
method to measure a bridge moving in the wind, for example.
