Geln,

Assuming you mean half-hemisphere....

Why not get a receiver capable of all three main systems - GPS, Galileo, and 
Beidou - and configured to use them.  As Bob said, all you need is a reasonable 
number of satellites, and receiving all three systems increases the changes of 
that happening.

Getting both the 2.3 and 1.5 GHz signals can increase accuracy as well.

Perhaps you need something better than that can provide - I don't know.

Cheers,
David
