Design of GNSS jamming propagation simulator using ITU-R P.1546 propagation model

Abstract

As Location Based Services(LBS) are developing rapidly in the mobile and information technologies, Global Navigation Satellite System (GNSS) including GPS also becomes very important. But, there is critical problem that GNSS signal is very weak and easily damaged by the jamming attack. The GNSS jamming can cause the social confusion by making the GNSS receiver broke down or malfunctioned. The prediction and analysis of the jamming propagation should be needed to prevent and cope with the damage of the jamming. So, we are developing GNSS interference verification platform which simulates a jamming environment and provides the effect by the jamming propagation. In this paper, we present the design of GNSS jamming propagation simulator based on ITU-R P.1546 propagation prediction model. This simulator will provide the analysis of the jamming propagation based on the geographical information and the damage status of the GNSS receiver by the jamming effect in Korea territory.
