The aim of the study was to investigate the effect of the angle only measurements on orbit determination accuracy. Telescope angle measurements are simulated using System Tool Kit simulation software. Noise is added to the data as well. The effect of various factors on estimation accuracy such as, measurement frequency, observation duration, and number of observation sites (i.e., telescopes) are investigated. Estimation methods, extended and unscented Kalman filters are employed and compared.

Nonlinear aeroservoelastic modelling and analysis of aircraft with control surface freeplay Yurtsever, Utku; Şahin, Melin; Kayran, Altan; Department of Aerospace Engineering (2022-11-24) In this study, nonlinear aeroservoelastic analysis of aircraft with control surface freeplay is performed using the fictitious mass approach. For the demonstration of the nonlinear aeroservoelastic analysis methodology, an available very light aircraft (VLA) design configuration is selected. The aeroelastic model of the aircraft is obtained by combining the structural and aerodynamic models of the aircraft, which are prepared by the finite element modelling and analysis tool MSC.Patran/MSC.Nastran and the a...
Uncertainty analysis of coordinate measuring machine (CMM) measurements Sözak, Ahmet; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2007) In this thesis, the measurement uncertainty of Coordinate Measuring Machine (CMM) is analysed and software is designed to simulate this. Analysis begins with the inspection of the measurement process and structure of the CMMs. After that, error sources are defined with respect to their effects on the measurement and then an error model is constructed to compensate these effects. In other words, systematic part of geometric, kinematic and thermal errors are compensated with error modelling. Kinematic and geo...
Accretion in strong field gravity with eXTP De Rosa, Alessandra; et. al. (Springer Science and Business Media LLC, 2019-02-01) In this paper we describe the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related to accretion flows in the strong field gravity regime around both stellar-mass and supermassive black-holes. eXTP has the unique capability of using advanced “spectral-timing-polarimetry” techniques to analyze the rapid variations with three orthogonal diagnostics of the flow and its geometry, yielding unprecedented insight into the inner accreting regions, the effects of strong field grav...
Incipient motion of coarse solitary particles Gülcü, Besim; Göğüş, Mustafa; Department of Civil Engineering (2009) In this study the incipient motion of coarse solitary particles having different specific weights and shapes was investigated. A tilting flume of rectangular cross-section having a net working length of 12 m was used through the experiments. The slope of the channel and the discharge in the channel are the two basic variable parameters that determine the initiation of motion. Particles made of cement and mixture of cement and iron dust in certain ratios were used in the experiments with an obstructing eleme...
Convergence Error and Higher-Order Sensitivity Estimations Eyi, Sinan (2012-10-01) The aim of this study is to improve the accuracy of the finite-difference sensitivities of differential equations solved by iterative methods. New methods are proposed to estimate the convergence error and higher-order sensitivities. The convergence error estimation method is based on the eigenvalue analysis of linear systems, but it can also be used for nonlinear systems. The higher-order sensitivities are calculated by differentiating the approximately constructed differential equation with respect to the...
