 <p>Aside from the other good examples of how to use Core Location, also keep in mind the general technique for getting good kinematics results from a not-so-great sensor (e.g. smartphone location services) of <a href="http://en.wikipedia.org/wiki/Kalman_filter" rel="nofollow">Kalman Filtering</a>.</p> <p>It's a lot of math and testing and tweaking, but it does allow you to get what users would consider better results than simple data from the sensor provides.</p> <p>This is what's used in avionics and things like radar processing systems.</p>
