Abstract:	The LF band used for Loran-C navigation is susceptible to the effects of atmospheric noise. The two main components of LF atmospheric noise are background Gaussian noise and impulsive lightning noise. As the FAA continues in its efforts to incorporate Loran-C into the National Airspace System for use as a supplementary navigation aid, it is necessary to develop a better understanding of the effect of atmospheric noise on the accuracy, availability, and integrity of Loran-C. A simulation facility has been developed which provides a controlled, repeatable, and realistic noise environment for the calibration and testing of Loran receivers. This paper describes three of the noise models used in the simulator, and how they are created, calibrated, and used in the evaluation of Loran receivers.
