    • Abstract
  • With the development of navigation system, the frequency band for navigation is becoming more and more crowded, which accounts for the interference among different navigation systems and navigation satellites becoming severer and severer. In this paper, binary subcarrier is introduced. By designing the frequency and phase of the subcarrier, the satellite signals become almost orthotropic, for which the crosscorrelation interference can be mitigated affectively.
