    Abstract
  • The frequency band between 5.010.MHz and 5.030.MHz allocated as C band has been used as a candidate in the global navigation satellite systems (GNSS) along with more and more navigation services in L band. The potential benefits and technical requirements of C band for satellite navigation have been analyzed before. However the degradation of effective carrier-power-to-noise density ratio(Δ (C/N 0) eff) based on code tracking spectral sensitivity coefficient(CT_SSC) as a compatibility assessment methodology for potential GNSS radio frequency compatibility in C-Band has not been discussed clearly. So the compatibility of the signals in the C band between BeiDou (BD) B1C and GPS L1C, L1C/A, Galileo E1Os as the interoperability or classical signals in L band is analyzed. Simulation results reveal the interference degree between BD III B1C and GPS L1C/A, L1C, Galileo E1OS. The results can also reveal that the multiplexed binary offset carrier (MBOC) and binary phase shift keying (BPSK) modulation is not appropriate for C band.
