Abstract
Embodiments of the present invention recite a method and system for limiting the functionality of a mobile electronic device. In one embodiment, a Global Navigation Satellite System (GNSS) receiver configured to determine a GNSS Doppler frequency shift measurement corresponding to a GNSS signal. A control component is configured to control an operation of the mobile electronic device in response to a control signal which is generated when the GNSS Doppler frequency shift measurement is used to determine that the speed of the mobile electronic device exceeds a speed threshold.
