【摘要】 北斗卫星系统是我国具有自主知识产权的第一代卫星导航定位系统,具有授时、定位、短报文的三大功能。介绍基于北斗卫星预警发布系统的应用需求分析、功能流程设计与实现、系统应用实验和效果检验。通过该系统的设计和应用,有效解决了偏远农村、山区预警发布"最后1公里"的瓶颈问题,扩大了预警发布的覆盖面;弥补了城市密集区预警信息手机短信发布延迟和信息阻塞的缺陷,极大提高了预警发布的时效性;实现了灾情实时上传,形成了发布、接收、反馈于一体的预警发布体系,为北斗卫星在我国应急体系建设中的应用提出了建议。更多还原

【Abstract】 The Beidou satellite is the first-generation satellite navigation system with independent intellectual property right in China,having the functions of timing,positioning,and short message transmission.The needs analysis,system functions,and structure of the Beidou Satellite Early Warning Release System are described.The system is an effective solution to the bottleneck problem of early warning release in remote rural and mountainous areas,and it expands the coverage of warning service;in the densely populated urban area,the problems of delay and information blocking of releasing warning information are solved,which greatly improves the timeliness of warning release.The system achieves the real-time uploading of disaster release information,and becomes a warning dissemination system that combines information releasing,receiving,and feedback together.Some suggestions are given for the application of the Beidou satellite in the emergency response system of China.更多还原
