Improvement of UAV Positioning by Information of Inertial Sensors

The paper deals with the problem of improving unmanned aerial vehicles positioning accuracy by information of inertial sensors based on technology of microelectromechanical systems. The nonorthogonal redundant configuration of inertial sensors is proposed. An algorithm of processing redundant information is given. Simulation results are shown. The represented algorithm improves accuracy of unmanned aerial vehicle positioning during difficult access to positioning system signals.
