I am working on location tracking application. Everything is fine but the problem is when GPS is weak the application is running and showing wrong values. So what I need is, if the GPS signal strength is high or weak a text label should display high and weak. If and only if the text is high(GPS signal) the application should run. I have taken code from this link [nokia community](http://developer.nokia.com/Community/Wiki/A_Windows_Phone_8_Run_Tracking_App_in_100_Lines_of_Code!). Is it possible to trace GeoPositionAccuracy compared to any value or boolean?
