摘要
高精度的协同导航是实现多飞行器编队飞行的关键,而编队构型是影响协同导航定位精度的重要因素。为了实现高精度的协同导航,建立了多飞行器协同导航系统模型,分析了编队构型及其动态变化对协同导航定位精度的影响,确定了使系统完全可观测的编队构型;进而,基于系统可观测度分析方法建立了协同导航定位精度评价模型,得到了多飞行器协同导航最优编队构型。仿真结果表明,相较于采用非最优编队构型,采用最优编队构型时的定位精度可提高75%以上,有效提升了编队飞行器的协同导航定位精度。
High-precision cooperative navigation is the key to realizing multi-aircraft formation flying,and formation configuration is an important factor affecting the positioning accuracy of cooperative navigation.In order to achieve high-precision cooperative navigation,a multi-aircraft cooperative navigation system model is established,the effect of formation configuration and its dynamic change on cooperative navigation positioning accuracy is analyzed,and the formation configuration that makes the system fully observable is determined.Then,the cooperative navigation positioning accuracy evaluation model is established based on the system observable degree analysis method,and the optimal formation configuration of multi-aircraft cooperative navigation is obtained.The simulation results show that compared with the non-optimal formation configuration,the positioning accuracy of the optimal formation configuration can be increased by more than 75%,which effectively improves the cooperative navigation positioning accuracy of the aircraft formation.
