Abstract:	The use of data and pilot channels in next generation GNSS signals is envisaged and will provide potential advantages in signal processing of a receiver. In designing GNSS signals, a trade-off between navigation data bit rate and signal power on data channel is an important factor affecting the overall system performance, therefore it needs a detailed analysis. This paper presents the relationship between optimal data rate and signal power split of future GNSS signals in terms of the available C/N0 region focusing on the strategy of optimum data/pilot combining algorithm (e.g., pilot-only tracking, data-only tracking, or combined tracking), the optimum bit rate, and finally the optimum signal power sharing between data and pilot channels.
