Abstract

A system, method and device for frequency acquisition. In particular, the embodiments allow for a mobile telephone to simultaneously receive data and/or voice signals while acquiring a GPS signal for its navigation feature. The system, method and device of the present embodiments employ a digital rotator and a local oscillator in concert to acquire the respective signals, correct any frequency errors associated with those signals, and maintain a local timing reference suitable for receiving and transmitting data through a mobile network while simultaneously providing an accurate location through a GPS system.
