| 摘要: |
| 针对集群飞行器分布式协同定位中面阵任务构型下因几何精度衰减引起的协同定位精度差的问题，提出了一种适用于面阵任务构型的集群飞行器分布式协同定位导航方法。分析了面阵任务构型的特点与该构型下的几何精度衰减问题，并以几何精度衰减值为参考提出了一种向量偏移优化方法。该方法为面阵任务构型下的基准飞行器设计偏移向量，在不改变飞行器实际位置的前提下优化用于协同定位的集群飞行器构型，实现了在面阵任务构型下的高精度定位。仿真结果表明，相较于未使用向量偏移优化的基于到达时间差、频率差的协同定位算法，所提算法在面阵任务构型下的定位精度显著提升，增强了协同解算的稳定性。 |

| Abstract: |
| To address the degradation of cooperative localization accuracy in cluster aircraft distributed cooperative navigation under planar formation mission configurations caused by geometric dilution of precision (GDOP), a distributed cooperative navigation method suitable for planar formation tasks is proposed. The characteristics of the planar task configuration and the associated GDOP degradation problem are analyzed. By using the GDOP metric as a reference,a vector-offset optimization approach is introduced. The proposed method designs offset vectors for benchmark aircraft within the planar configuration to optimize the cooperative localization geometry without altering the actual flight positions. This enables high-precision localization under planar mission scenarios. Simulation results show that, compared with the cooperative localization algorithm based on time difference of arrival(TDOA) and frequency difference of arrival(FDOA) measurements without vector-offset optimization, the proposed method significantly improves the positioning accuracy under planar-array mission formations and enhances the stability of the cooperative solution. |
