Why is my CLLocation speed so inaccurate?

Question

I´m playing a bit with the iPhone SDK and I want to show the current speed in my application. There are so many apps that can do that really precise, especially for low spee

Please try following in your code :

speedLabel.text = [NSString stringWithFormat:@"SPEED(Km/Hr): %f", [location speed]*3.6];
latitudeLabel.text = [NSString stringWithFormat:@"LATITUDE: %f", location.coordinate.latitude];
longitudeLabel.text = [NSString stringWithFormat:@"LONGITUDE: %f", location.coordinate.longitude];
CLLocationDistance meters = [location distanceFromLocation:orginalLoc];
distanceLabel.text = [NSString stringWithFormat:@"DISTANCE(M): %f", meters];
