Satellite power enhancement technology is a key technology to improve the capability of satellite anti-interference and has very important application value. Aiming at the multi-access interference of GPS satellite power enhancement signal to the same frequency signal, this paper analyzes the mechanism of self-interference and mutual interference between signals. The interference of GPS P-code power enhancement signal to P-code and C/A-code expected signal under single-satellite enhancement and multi-satellites enhancement was quantitatively evaluated from multiple dimensions by using the equivalent carrier-to-noise ratio reduction calculation method based on spectral separation coefficient The results show that under the same conditions, the interference of P codes to C/A codes is larger than the self-interference between P codes; At the same time, the interference degree of multi-satellites enhancement is more significant than that of single-satellite enhancement; Power enhancement can effectively improve the carrier-to-noise ratio, but when the amplitude of enhancement exceeds a certain value, the interference effect will be greater than the power enhancement effect, and the carrier-to-noise ratio will no longer increase.
