Abstract:
1. A method for processing GPS and BOC positioning signals in a satellite positioning device, including a match filter, an input sample memory, a code generator and a processor for processing the GPS positioning signal, the method comprising: determining, by the processor, if signal samples of the GPS positioning signals from the input sample memory match a dispreading code generated by the code generator with the match filter that results in filtered signal data; storing, by the processor, the filtered data in a coherent memory; transforming, by the processor, the filtered data from the coherent memory with a fast Fourier transform and saving the transformed data in a non-coherent memory; and peak sorting, by the processor, the transformed data to detect if a GPS satellite has been acquired; reconfiguring the match filter, input sample memory and code generator in the satellite positioning device for processing both the GPS positioning signal and the BOC positioning signal.
