In this work, an alternative navigation scheme for improving the performance of inertial navigation systems onboard guided munitions, missiles and unmanned platforms is investigated, to be used in case of a theater or country-wide GNSS (Global Navigation Satellite System) jamming scenario. Previously laid ground based beacon network is used by the aerial platform's EO/IIR (Electrooptic/ imaging infrared) seeker for bearing-only measurements and position updates are performed by the use of modified artillery survey algorithms based on triangulation techniques. Three angle-only passive position fixing techniques are offered for position updates. Effects of beacon placement geometry are analyzed and a tool for the optimal laying of beacons under several factors and, constraints is developed.

Modelling and Testing of Terrain Aided Inertial Navigation Algorithms for Land Vehicles Sonmez, T.; Ekutekin, V.; Ozkan, M. (2009-09-23) Sensing the terrain and using it for aiding the inertial navigation system has been widely used in air platforms since the 1960's. TERCOM and SITAN are well-known algorithms for sensing the terrain with a radar altimeter and calculating a correction for the navigation states according to a digital elevation map. In the absence of GPS signals, it is extremely important to be able to make positional fixes. In this paper, first we developed a simulation environment for a conceptual application of TAN (Terrain ...
Development of an autopilot for automatic landing of an unmanned aerial vehicle Arıbal, Seçkin; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2011) This thesis presents the design of an autopilot and guidance system for an unmanned aerial vehicle. Classical (PID) and modern control (LQT, Sliding Mode) methods for autonomous navigation and landing in adverse weather conditions are implemented. Two different guidance systems are designed in order to navigate through waypoints during normal and/or emergency flight. The nonlinear Pioneer UAV model is used in controller development and simulations. Aircraft is linearized at different trim points and total a...
Improving operational performance of antennas on complex platforms by arranging their placements Bayseferoğulları, Can; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2010) The aim of this thesis is to improve the operational performance of the communication antennas mounted on complex platforms such as aircrafts and warships by arranging placements of these antennas. Towards this aim, primarily, in order to gain insight on the influence of geometrically simple structures composing the platform on antenna performance, a quarter wavelength monopole antenna placed at the center of a finite square ground plane is studied by using uniform Geometrical Theory of Diffraction (GTD). B...
Comparison of Outer Rotor Radial Flux and Axial Flux PM Motors for CMG Application Ertan, Hulusi Bülent (2014-09-05) Control moment gyroscopes (CMG) are used in modern satellite applications for attitude control of satellites. The volume and mass of the instruments is very important in such applications. In this context, integrating the mass of the CMG, on the stator of the motor, promises to save space and mass. Radial-flux outer-rotor motor is a promising configuration in that respect. In this paper, using such a PM motor is considered for control moment gyroscope applications. The design of the motor must be made such ...
Design and analysis of a mode-switching micro unmanned aerial vehicle Cakici, Ferit; Leblebicioğlu, Mehmet Kemal (SAGE Publications, 2016-12-01) In this study, design and analysis of a mode-switching vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV) with level flight capability is considered. The design of the platform includes both multirotor and fixed-wing (FW) conventional airplane structures; therefore named as VTOL-FW. The aircraft is modeled using aerodynamical principles including post-stall conditions. Trim conditions are obtained by solving constrained optimization problems. Linear analysis techniques are utilized for trim ...
