- The pseudo-random code is an important part of the satellite navigation and positioning signals, its performance directly affects the accuracy of positioning system. Especially, in navigation and communication integrated system, the system's anti-jamming, anti-multipath fading, anti-intercepted, anti-multiple access and synchronization are all closely related with the pseudo-random sequence.In this paper, we study the characteristics of PN codes in navigation and communication integration system, including correlation, balance, run length and linear complexity. Furthermore, it puts forward and constructs a novel imLogCheby sequence successfully. The imLogCheby sequence’s uncertainty and randomness has been improved comparatively while maintaining the main advantages of the chaotic sequence with a large number and good confidentiality. We also carry out dynamic simulation in Simulink system to verify the feasibility of the new sequences in the integration system of navigation and communication and their advantage performance in system.
