Abstract:	An analytic statistical model is presented for aggregate ground-based continuous interference to airborne Global Positioning Systems receivers employed in the U.S. Air Traffic System. The model computes total interference from a random number of uniformly distributed ground based emitters utilizing statistical path loss models to account for the propagation environment in the vicinity of metropolitan airports.Numerical results are computed at the GPS L1 center frequency (1575.42MHz) for the mean and standard deviation of the aggregate interference power density as well the associated probability distribution function. Comparisons are made between results from the new model and prior interference analysis studies.
