A method includes outputting a plurality of simulated global navigation satellite system (GNSS) and interference signal pairs comprising a simulated GNSS signal and a simulated interference signal. Each of the simulated GNSS signals, or the simulated interference signals, has an associated reference signal. A calibration GNSS signal that combines the simulated GNSS signals and the associated reference signals, or a calibration interference signal that combines the simulated interference signals and the associated reference signals is received. A phase, time, or a power offset is calculated for the simulated GNSS signals based on the calibration GNSS signal and the associated reference signals, or for the simulated interference signals based on the calibration interference signal and the associated reference signals. A corrected plurality of simulated GNSS and interference signal pairs are output based on the calculated phase, time, or power offset for the simulated GNSS signals or for the simulated interference signals.
