基于低轨物联网星座的星地融合技术及窄带业务研究OA
Research on space-ground integration technology and narrowband services based on low orbit IoT constellations
随着北斗短报文的推广应用,基于低轨物联网卫星系统的星地融合网络技术也在快速发展,为窄带数据的泛在传输提供了通道.针对物联网传感数据、短消息数据两类窄带数据业务的泛在传输需求,提出基于低轨物联网卫星系统的天地一体化网络结构、关键技术及通信流程,该方案不仅可作为除北斗短报文外的第二条通信通道,更能在B2B/B2C端带来更丰富的传输能力和业务体验.
With the promotion and application of Beidou short message,the space-ground integrated network technology based on low orbit IoT satellite system is also developing rapidly,which provides a channel for ubiquitous transmission of narrowband data.To meet the ubiquitous transmission requirements of two types of narrowband data services,IoT sensor data and short messege data,a space-ground integrated network architecture,key technology and communication process based on low orbit IoT satellite system are pro-posed,this solution can not only serve as a second communication channel besides Beidou short message,but also bring richer transmis-sion capabilities and service experiences to both B2B and B2C ends.
