The low earth orbit (LEO) and medium earth orbit (MEO) constellation network with inter-satellite links(ISL) is a critical element in the satellite information transfer network. A 2-layer LEO/MEO constellation model with ISL is constructed. The MEO and LEO constellation networking is analyzed. The simulation system of the LEO/MEO constellation networking in the satellite information transfer network is designed. With STK simulation, the LEO/MEO constellation structure, connection/disconnection time of links between satellites, links between satellite and ground, and link transmission time delays are obtained. The topology change data of the satellite information transfer network is analyzed. The study achievements are applied into the construction of the satellite information transfer network and provide the foundation for the comprehensive performance evaluation of the satellite information transfer network.
