Abstract:
1. A method for Doppler-based control of a mobile device, said method comprising: receiving at a base station a wireless signal comprising at least one Global Navigation Satellite System (GNSS) Doppler frequency shift measurement corresponding to a GNSS signal received at a mobile electronic device; determining a speed of said mobile electronic device based at least in part on said at least one GNSS Doppler frequency shift measurement, wherein an expected range rate is subtracted from a measured value indicating a speed of said mobile device and wherein said expected range rate is derived by calculating a dot product of at least one line-of-sight vector to a GNSS satellite and a velocity-in-space of said GNSS satellite; controlling from said base station an operation associated with said mobile electronic device when said speed exceeds a speed threshold; and generating an audible notification by said mobile electronic device when a user input device in said mobile electronic device is operated.
