  • Due to the low signal strength of GNSS signals upon reaching the ground, they are highly susceptible to unintentional or intentional human interference, which can severely impact the availability of navigation and positioning services. Therefore, locating and eliminating sources is of paramount interference. For common jamming interference, current positioning methods mainly involve processing the raw sampled signals, which often leads to issues with complex equipment, high computational demands, and high costs. This paper proposes a method for locating GNSS interference source using the carrier-to-noise ratio (C/N0) measurements from standard commercial receivers. By estimating the interference signal strength difference through C/N0 measurements, the position of the interference source can be calculated. Field test results indicate that, under line-of-sight conditions, in a monitoring area of approximately 11 400 square meters, this method can achieve a Mean Absolute Error (MAE) of 13.17 meters with minimal time consumption, thereby effectively locating the interference source. The proposed method does not require any modifications to the receiver's hardware or software, making it simple to implement and cost-effective, which is advantageous for engineering applications.
