GPS Impetus

Keep your GPS rolling without eating your battery

A background service accessing the GPS periodically keeps the Android Last Known Location recent and accurate and the GPS warm so that other apps get locations faster

GPS Tips

Your phone needs to be able to see satellites to get a fix so GPS works best outdoors on a clear day away from tall buildings 

GPS is most likely to work if you keep your phone in one of these places (best to worst):

in your hand
on a bike mount
on a car mount
in a thin outside pocket
at top of a thin bag
by a window inside 
inside low rise buildings

How GPS Impetus Works

The background service tries to get both satellite information and a GPS fix about every 10 minutes

If it can get an GPS fix easily it exits as the GPS is clearly warm and working well.

It also exits quickly if it can't get a good sight of satellites because you are likely indoors.

When satellite visibilty is reasonable the app gives more time to getting fixes to get the GPS up to speed
