Precise Time in your Pocket: Timing Performance of Android Phones

Ciro Gioia, Sophie Damy, Daniele Borio

Abstract:	This paper investigates the stability of timing solutions obtained from smartphones as the availability of raw GNSS measurements from these devices is enabling the development of new timing services. The timing performance of several Android smartphones is evaluated using the Allan Deviation (ADEV) to characterise the clock biases and drifts. This paper analyses data collected in various conditions (static and kinematic), over long durations (one day of continuous logging in static conditions) and with a variety of devices (four different mobile phones).
