Radio frequency interference (RFI) localization is important for ensuring the accuracy and integrity of global navigation satellite system receivers in numerous applications. In this letter, an efficient RFI localization technique is presented based on differential received signal strength (DRSS) measurements from crowdsourcing devices. A DRSS weighting scheme allocates weights to the position solutions of the receivers that detect the RFI. The weighted centroid of the receiver positions generates the RFI location. The method presented in this letter can also provide an initial estimation for the conventional iterative localization approach to improve localization accuracy and convergence speed. Simulation results are presented to demonstrate the effectiveness of the proposed method being used independently or integrated with the iterative method.
