A method for the frequency determination of a local oscillator (LO) is presented to facilitate reception of the maximum number of satellite signals via the use of a multi‐global navigation satellite system (GNSS) receiver under interference. The authors have herein suggested a model for estimating the number of GNSS satellites with changing LO frequency. This estimation model was derived based on GNSS and interference spectra, used to determine the LO‐frequency value to avoid interference and facilitate reception of maximum GNSS signals. The proposed method was verified by means of an experiment involving the use of software‐defined radio receiver and actual GNSS signals. The authors expect the proposed method to be the basis of anti‐interference processes in reconfigurable GNSS receivers.
