覆盖指定区域的卫星通信组网虚拟仿真实验教学创新研究

Study of Teaching Innovation of Virtual Simulation Experiment in Satellite Communication Network in the Defined Area

卫星通信组网存在的空间跨度巨大、轨位受限、频率受控、系统复杂且节点动态可变等因素,导致实体实验平台建设成本极高,且无法开展系统级的多因素实验教学活动,开展卫星通信组网虚拟仿真实验教学是必要的。重庆邮电大学信息通信技术与网络国家级虚拟仿真实验教学中心凸显信息通信专业特色,依托科研项目成果转换,开发覆盖指定区域的卫星通信组网虚拟仿真实验教学系统,以“强实践动手、铸工程素养、培创新能力”为培养理念,建设“学、践、研、赛、创”五位一体的教学资源,避免传统实验教学对卫星通信组网设计不可见、高成本、空时受限等问题,激发学生工程意识,提高实践创新能力。

Due to the huge space span,limited orbit,controlled frequency,complex system and dynamic node of satellite communication network,the construction cost of its actual experiment platform is very high,so that it is unable to carry out system level multi-factor experiment teaching activities.Therefore,it is necessary to carry out virtual simulation experiment teaching of satellite communication network.The national virtual simulation experimental teaching center of information and communication technology and network of Chongqing University of Posts and Telecommunications highlights the characteristics of information and communication specialty.Relying on the transformation of scientific research achievements,it has developed a virtual simulation experimental teaching platform of satellite communication network for covering designated areas.With the cultivation concept of"strengthening practice,casting engineering literacy,and cultivating innovation ability","learning,practice,research,competition,and innovation"platform has been constructed.The five in one teaching resources could effectively avoid the problems invisible,high cost,and space-time limitation in traditional experimental teaching,which has significantly stimulated students'engineering consciousness and improved their practical innovation ability.
