一种基于数据链的双格网协同导航方法与计算机仿真
A Dual Grid Collaborative Navigation Method and Computer Simulation Based on Data Link
摘要
Abstract
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 pro-posed.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 a-chieved 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.关键词
