Abstract:
High performance shipborne GNSS receiver with strong anti-interference ability and supporting compatibility and interoperability becomes more and more popular. The impact of data/pilot cross-correlation on code tracking performance is investigated, considering the characteristics of Beidou and GPS signals. Based on the code set given by the interface control document (ICD), the optimized code pairs optimization for the Beidou and GPS signals are presented. The optimized data/pilot code pairs could significantly mitigate the intra-channel (i.e., data/pilot) codes cross-correlation, and then improve the code tracking performance of the Beidou and GPS signals.
