Design and Implementation of LEO Constellation Simulation System Based on Distributed Simulation Platform

Abstract

The paper designs and implements a low-orbit constellation simulation system based on the distributed simulation platform. Based on analyzing the composition and the service process of the LEO constellation system, the overall architecture and index system of the LEO constellation simulation system are proposed. Taking the typical application scenario of the LEO constellation as an example, the operation process of the simulation scenario is planned and designed, and the evaluation methods of the overage, capacity, delay, bit error rate, and other indicators of the LEO constellation system are given. By using the component modeling method on the distributed simulation platform, the entities in the simulation system are modeled, and the visual display of the simulation system is realized through secondary development based on cesium digital earth. The LEO constellation simulation system can provide a verification environment for its construction and a basis for the determination, optimization, and upgrading of technical status.
