your location on earth should not be a factor in satellite acquisition and tracking. the gps satellites are in an orbital plan which allows a minimum of 5 satellites to be in view at any point on earth. gps units only need 4 satellites to make an accurate reading.
the usual culprits in measurement inaccuracies are direct line of sight blockage (buildings, hills, mountains, etc.), bad weather (the signal speed changes as it travels through the atmosphere), and multipath errors (signals bouncing off buildings, etc.).
so to answer your question about location, in general, it doesn't matter where you are. like some of you, my handygps unit is defective and i returned it for an exchange. i haven't received the new one yet; i still need to talk with nexian about that.
