Using following method: Code (Text): locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 10, locationListener); ...I get widely swinging accuracies, in open space I achieve an acceptable 5-10 meters deviation, but along a tree-lined street or with tall builders around me, I get 15-20 meters deviation, and when I step indoors, I get even worse readings. Apparently, the readings are 68/100 accurate, in other words, the probability of 5-10 meters deviation is 68/100. Sooo, it's not the best. Has anyone tried the European Galileo satellites? If so, can you share the "how-to"?
