导航类微纳集群系统构建技术研究

Research on Construction Technology of Navigation Micro-nano Swarm System

摘要:

微纳卫星具有小型化、研制周期短、开发和发射成本低、可组网运行等一系列优点,在通信、遥感和导航等领域中都得到了快速发展,单颗微纳卫星功能单一,能力相对薄弱,因此多采用集群的方式开展工作。如何结合卫星研制、能力形成等多考量角度形成微纳集群系统构建显得尤为重要。文章以微纳集群协同实现导航类任务为前提,从卫星研制周期、发射响应时间、能力形成时间等角度提出一种导航类微纳集群系统构建技术,并从任务综合效能满足角度对所设计的集群进行方法层面的优化。系统建设能够为指定区域提供长期持续导航服务及有效的应急增强导航服务。

Abstract:

With a series of advantages such as small size, short development cycle, low development, and launch cost, and network operation, micro-nano satellites have been rapidly developed in the fields of communication, remote sensing, and navigation, etc. Single micro-nano-satellites are relatively simple in function and weak in capability, so they mostly work in the way of swarms. How to combine satellite development, capability formation, and other multi-consideration perspectives to form a micro-nano swarm system construction is particularly important. The paper proposes a technique for building a navigation micro-nano swarm system from the perspectives of the satellite development cycle, launch response time, capability formation time,and optimizes the designed swarm at the methodological level from the perspective of comprehensive mission effectiveness satisfaction. The system construction can provide long-term continuous navigation service and effective emergency enhanced navigation service for the designated area.
