Abstract
Traditional methodology and mathematical model neglected the influence of secondary code which is a commonly component in new signal structure onto the assessment of multi-system GNSS compatibility and did not quantificational give the condition under which the model for the signals with long code and high data rate can be simplified. In this paper, through the exploration of Galileo E5 signals, the influence of secondary code onto the spectral separation coefficient (SSC) was discussed. Based on that conception, we modified the existing formula and quantificational presented a threshold of data rate and length of primary and secondary code so that the traditional methodology can be replaced by a simplified model without gigantic calculating time and quantity. The power spectral density (PSD) and SSC of assumed signals which meet the threshold above was respectively calculated. The simulation results prove the correctness of the proposed assessment model.
