Method for determining a change in a communication signal and using this information to improve sps signal reception and processing

A fixed to the communication port or transceiver mobile positioning system receiver method and device for determining. In a typical method, determined the change of the signal receiver communication manner. According to the change of the parameter, and source automatic to the SPS satellite according to parameter processing the SPS signal. According to the method is detail, the wavelength of claims a layer of fluctuation communication signal, the parameter for assigning to is in process of SPS signal is silicon SPS signal frequency band of the SPS satellite motion information. A in one embodiment, the wavelength of communication signal is the change for transmitting information response power control command. The invention also described device, comprising a SPS receiver and communication receiver's mobile communication system.
