Beschreibung
Zusammenfassung:	A mobile communication device includes a global navigation satellite system (GNSS) receiver for receiving GNSS signals, a radio frequency (RF) receiver for receiving RF signals and a voltage controlled oscillator supplying an oscillator signal to the GNSS receiver and the RF receiver. The GNSS receiver and the RF receiver use the oscillator signal to receive the GNSS signals and the RF signals. The mobile communication device also includes a processor for initializing and/or adjusting a model of a frequency behavior of the voltage controlled oscillator, and uses the model to track the GNSS signals when computing a location of the mobile communication device.
