Abstract

The collaboration among swarmed aircraft can provide additional observation to improve the integrity of its onboard navigation systems. But due to the limitation on relative communicating and measuring burdens, adopting all the observations between aircraft in the swarm is inefficient. The geometry of the collaborated partners is a key factor that influences the effectiveness of the navigation integrity augmentation, which needs to be optimized in collaborative integrity augmented navigation. In this paper, the integrity augmented navigation method for aerial swarm based on collaborative partner optimization is proposed. The geometry constructed by the GNSS satellites and the cooperative partners in the aerial swarm are analyzed dynamically, and the augmented integrity protection levels with different collaborative relationships are predicted to distinguish the partner essential for navigation integrity augmentation. Then the collaborative partner makes a key contribution to integrity augmentation adopted in collaborative navigation integrity monitoring, improving the efficiency of the collaborative navigation. The simulation results indicate the effectiveness of the proposed cooperative partnership optimization strategy, as well as the superiority of the proposed method compared with the traditional independent integrity framework in improving the integrity protection level and fault detection capacity.

优化动态伙伴选择的协作导航完整性增强方法

蜂群飞机之间的协作可以提供额外的观测数据，从而提高机载导航系统的完整性。但由于相对通信和测量负担的限制，采用蜂群中飞机之间的所有观测数据效率不高。协作伙伴的几何形状是影响导航完整性增强效果的关键因素，需要在协作完整性增强导航中加以优化。本文提出了基于协作伙伴优化的航空蜂群完整性增强导航方法。通过动态分析机群中 GNSS 卫星与协作伙伴构建的几何图形，预测不同协作关系下的增强完整性保护等级，从而区分出对导航完整性增强至关重要的协作伙伴。然后，协作伙伴对协作导航完整性监测中采用的完整性增强做出了关键贡献，提高了协作导航的效率。仿真结果表明了所提出的合作关系优化策略的有效性，以及与传统的独立完整性框架相比在提高完整性保护水平和故障检测能力方面的优越性。
