%X Interference coexistence of satellite meteorological service in Argos system and railway dispatching system was studied in the spectrum bandwidth around 450MHz. Focusing on the possible interference in four cases, the interference from meteorological satellite to the train, the interference from meteorological satellite to the railway station, the interference from railway station to the meteorological satellite earth station, the interference from train to the meteorological satellite earth station. The realistic system parameters and radiation pattern were used, combined with track characteristics of Argos meteorological satellite to analyze the isolated distance needed and the coordination area around meteorological satellite earth station. Simulations demonstrate the isolation degree and the isolation distance of the four kinds of interference conditions.
