Inaccurate GPS on Nexus 7

[propeller10]

for the past few days Google Maps have been giving me inaccurate GPS location. The blue pinpoint moves around as if it is confused about my location. It used to be dead accurate. It also shows the wrong direction I'm facing. How do I fix this?

One thing to try. Download an app like GPS Test Plus. With something like that you see all the in view SATS and their signal to noise ratio. Also it gives accuracy in feet. At least this may tell you if you have a good GPS signal. It's a place to start.
