Design and Verification of the Universal Tracking Channel for the GNSS Receiver with the Interoperability at Ll(1575.42MHz)

摘要

According to the planning, in the near future a majority of navigation systems would broadcast navigation signals centered at LI. To take full advantage of those signals, the universal tracking channel is suitable for the GNSS receiver with the interoperability, for its convenience to adapt to different hardware configuration and to upgrade for the new signal structure. Summing up tracking loop structures of different signals, the design of the universal tracking channel is presented which can track any signal as long as setting proper parameters. In true satellite signal environment, the configured channel can rightly realize the signal tracking and demodulation. Thus the effectiveness of the design is proved.
