Along with the growing of Global Navigation Satellite Systems (GNSS), position, navigation and time services provided by GNSS will play more and more important role in geo-information science field. Meanwhile, inter-system interference becomes one of the most important issues for precision position applications when multiple systems like GPS, GLONASS, Galileo and Compass are all in service. Usually, spectral separation coefficient (SSC) and effective carrier-power-to-noise density ratio based on SSC are used as major parameters for the assessment of GNSS interference, but they only assess the impact of interfering signals on prompt correlator channel of GNSS receiver without considering its impact on code tracking loop. Code tracking spectral sensitivity coefficient (CT_SSC) which is a more comprehensive parameter can provide better assessment regarding the impact of interfering signals on the code tracking loop. This paper provides an in-depth analysis of CT_SSC calculation methodology and presents an improved calculation method of effective carrier-power-to-noise density ratio based on CT_SSC for GNSS interference analysis, and the simulation results verify the proposed calculation. Furthermore, Compass Phase II and Galileo navigation signals on B1/E1 bands are used as examples in this paper to conduct interference assessment by proposed method, and the results can guide navigation signal design and also provide valuable reference for precision position and navigation applications.
