SPACE INTEGRATED NETWORK: ROUTED INTER-SATELLITE NETWORK PRIMARY MODELING RESULTS

Abstract

The paper presents the first results obtained by modeling a routed inter-satellite network based on the parameters of the ReshUCube-3 space mission. ReshUCube-3 is a mission in which it is planned to launch a satellite constellation of four CubeSats. A network stack was proposed to provide the concept of a space integrated network. It is planned to use LoRa technology on the physical layer, and RPL as a routing protocol on the network layer. The model takes into account the orbital parameters of the satellite constellation, the antenna systems of spacecraft and ground station, and the parameters of radio modules. Based on this information, the analysis of inter-satellite communication channels was carried out. The maximum distance between the satellites, the energy properties of the channels, the average daily coverage time, etc. are determined. An important feature is the consideration of existing routes between satellites. It is planned that the proposed model will serve as a basis in the process of designing and operating an inter-satellite network.
