Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Technique of Increase of Accuracy of Determination of the Current Coordinates of Location of the Unmanned Aerial Vehicle A.V. KOMAROV In article the task of definition and correction of coordinates of location of the unmanned aerial vehicle when performing formation flying is set and solved. The technique of increase of accuracy of determination of the current coordinates of location of the UAV with use of the solution of relyefometrichesky KENS on the basis of the distributed system of dot measurements in group of the interacting UAVS differing in the fact that the autonomous solution of relyefometrichesky KENS on own measurements with the coordinate decisions executed by other UAVS in group and autonomous measurements of their relative situation on the basis of Bayesian approach to estimation is integrated is offered. The example of realization of the distributed correlation and extreme navigation system on the basis of interaction of two unmanned aerial vehicles is given. Results of statistical modeling of integration of the solution of the autonomous bespoiskovy KENS and secondary coordinate information transferred from other UAVS of group are presented. Results of modeling show increase of accuracy of determination of coordinates of location of the unmanned aerial vehicle in group.
