Since Global Positioning System signals in dense urban housing areas, in tunnels or indoors may be unreliable, unmanned aerial vehicle will not be able to fulfill its tasks if needed to pass such zones.

The approach can be useful for performing analysis of big amounts of unlabeled images that can be nowadays easily gathered, in particular by using unmanned aerial vehicle with mounted cameras. The approach is based on “softening” the initial clustering criterion and then using nonlinear optimization to find the optimal hypersurface that separates clusters.Item Dynamic Testing of UAV Navigation System(Kyiv, “Osvita Ukrainy”, 2017-10) Sineglazov, V.M.; Dolgorukov, S.O.The paper considers dynamic test table system for navigation sensors testing and verification.

In these problems, the optimal solutions to the lower level problems become possible feasible candidates to the upper level problem. A bilevel optimization is used for the navigation equipment test table design. The six lower level optimizations are driven by a top system level optimization by approach based on hybrid bilevel evolutionary algorithm using quadratic approximations.
