摘要

空天技术深入发展后，用户对空天系统的要求将是融合通信、遥感、导航卫星的天基信息服务系统，以向用户提供高速数据传输、直达用户的实时遥感服务、精确到厘米以内的高精度定位导航、分布式协同计算资源等服务能力，从而应用于丰富的服务场景。现有的通信、导航、遥感卫星存在软件协议和物理设施上的屏障，不能融合应用，远远不能满足天基信息服务系统的建设要求，因此，有必要研究通信、导航、遥感、计算在卫星上的融合。融合关键点是硬件和软件资源的可调度、可共享，以及高效能、高稳定性的载荷器件。基于此，深入分析面向卫星通导遥算融合的关键技术，并分析通导遥算融合的典型应用服务方式，最后通过仿真实验可验证融合后的效能提升。

Abstract

After the in-depth development of space technology

the user's requirement for space system will be anintegrated space-based information service system that integrates communication

remote sensing and navigation satellites in order to provide the user with service capabilities such as high-speed data transmission

real-time remote sensing services directly to the user

high-precision positioning and navigation accurate within centimetres

and distributed collaborative computational resources

so as to be applied to a rich variety of service scenarios. However

existing communication

navigation and remote sensing satellites have barriers in terms of software protocols and physical facilities

which prevent them from integrating applications and are far from meeting the requirements for the construction of space-based information service systems. Therefore

it is necessary to study the fusion of communication

navigation

remote sensing and computation on satellites. The key points of fusion are schedulable and shareable hardware and software resources

and high-efficiency high-stability payload devices. Based on thes

the paper introduced and analyzed the key technology oriented to the fusion

and analyzed the typical application service mode of communication

navigation

remote sensing and computation fusion. Simulation experiments verified the performance enhancement after fusion.
