About GPS On
A trivial Android application that asks for a GPS fix once a minute.
It maintains the GPS system "warm" so that you get a quick fix when you need one.
To use: Turn your GPS on and open the app.
The screen shows how many satellites are visible and are used, so you can get an idea of how close you are to a fix.
To turn off: Press the Stop button.
