摘　　要：针对卫星导航拒止条件下作战编队协同作战对相对/绝对导航定位的需求,提出了一种基于数据链的双格网协同导航方法,设计了测距信息与惯导紧密组合的地理导航滤波算法与相对导航滤波算法,实现了可不依赖地面固定基准和卫星导航的移动编队精确相对定位能力,同时可自适应接入编队内存在的精确地理位置信息实现整个编队的绝对定位。此外,为确保协同导航在定位基准数量不足、几何分布不佳等条件下的可用性,采用了基于质量等级制的导航源选择策略,使得待定位节点能够有效利用其他用户节点的定位信息,从而提升定位性能。最后,结合数据链协同导航技术方案和误差特性,构建了一种分布式的计算机仿真系统,结合典型场景对数据链双格网导航能力进行了验证,仿真结果充分表明了所设计方法的有效性。In response to the demand for relative/absolute navigation positioning in combat formation cooperative operations under GNSS-denied environment,a dual grid collaborative navigation method based on data link is proposed.Firstly,by adopting geographic navigation filtering algorithms and relative navigation filtering algorithms that closely combine ranging information with inertial navigation,precise relative positioning of mobile formations can be achieved without fixed ground station and GNSS.At the same time,accurate geographic location information existing within the formation can be adaptively accessed,achieving absolute positioning of formation members.In addition,to ensure the availability of collaborative navigation under conditions such as insufficient positioning benchmarks and poor geometric distribution,adopting a navigation source selection strategy based on quality grade,which enables the target node to efficiently utilize the positioning information of other user nodes,thereby improving positioning performance.Finally,a distributed computer simulation system is constructed by closely integrating the technical characteristics and error characteristics of the data link collaborative navigation system.The navigation capability based on the data link is verified in typical scenarios,and the simulation results fully demonstrate the effectiveness of the designed collaborative navigation method.
