var geo:Geolocation = new Geolocation();
 geo.addEventListener(GeolocationEvent.UPDATE, geolocationUpdateHandler);
 function geolocationUpdateHandler(e:GeolocationEvent):void
 {
     var altitude:Number = e.altitude;
     //Meters Per Second
     var mps:Number = e.speed;
     //Miles Per Hour
     var mph:Number = Math.round( (mps * 360000) / 160934.4 ) );
     trace( "altitude:", altitude, "meters per second:", mps, "miles per hour:", mph );
 }
