Display visible GPS satellites

This is a suggestion for a partly fix of #973. I put the "/" to the strings.xml for RTL compatibility.

For me no. I usually see 4 or higher. A position is available with 3
satellites, as the A-GPS can eliminate non-possible positions on the earth,
I haven't tested though to see what accuracy level this shows. I would
assume that if the sats drops below 3, the accuracy becomes poor enough
that we shouldn't be using it.
