陆海空天一体化信息网络发展研究

Development of Land–Sea–Air–Space Integrated Information Network

陆海空天一体化信息网络具有为陆基、海基、空基、天基等各类用户提供全球随遇接入、信息安全可靠服务的能力,是我国避免受制于人、实现网络强国的重要基础设施之一。立足于我国一体化信息网络的发展,本文运用文献调研、专家咨询的研究方法,梳理了陆海空天一体化信息网络的发展需求,开展了国内外典型系统的分析研究,总结了我国在先进陆海空天一体化信息网络方面存在的主要问题及差距,重点提出适合国情的融合网络架构初步设想及相应发展路线建议。研究认为,在推进陆海空天一体化信息网络论证设计和工程实施的过程中,应着重强化网络架构、技术体制、应用服务支撑体系方面的深度融合,兼顾通信、导航、遥感系统的功能融合,推动天基网络技术自主可控和高端产业升级,同步加强相关系统的安全防护能力建设。

The land–sea–air–space integrated information network is capable of providing globally accessible,safe,and reliable information services for land-,sea-,space-,and air-based users;it is an important infrastructure for China to maintain independence in the field and to become a cyberpower.This study uses literature research and expert consultation as the main research methods to summarize the development requirements of the land–sea–air–space integrated information network.After a detailed study on typical domestic and foreign systems,the major weaknesses of China’s land–sea–air–space integrated information network are summarized.Moreover,an integrated information network architecture and development routes are proposed.Specifically,we suggest that China should focus on the deep integration in terms of network architecture,technical system,and application services;integrate the communication,navigation,and remote sensing systems;promote technical independence and industrial upgrade of space-based networks;and strengthen its system security protection capabilities.
