Abstract: Embodiments of the invention are directed to a method of keeping track of and staying tuned to a transmitter even when a receiver is moving at a relatively high speed. Electronic equipment carried on fast moving vehicles and comprising receiving means can experience a shift in the frequencies received due to Doppler shift. Embodiments provide a way of taking such a Doppler shift into account by means of acceleration measurements of the electronic equipment. Some embodiments may be used in electronic equipment containing a GPS receiver or the like, where re-tracking of satellites can be power and time consuming.
