Flight Trajectory Planning for Unmanned Aerial Vehicles
Horeličan, Tomáš ; Jílek, Tomáš (referee) ; Gábrlík, Petr (advisor)
This thesis deals with the problem of planning a complete flight trajectory (ie. horizontal and vertical components) for unmanned aerial vehicles (UAV) with a main focus on maintaining a constant height and distance from the terrain. It includes the design of the trajectory planner itself, which is created in the Matlab environment. The design is mainly focused on small rotary aerial vehicles and drones. Main concepts of geolocation are discussed in the first chapters, which includes means of realization, basic terminology and theory that is needed in order to sufficiently track an object and its height on Earth. Principles of aerial survey, its use cases and means used in this thesis are also described. Following chapters present a complete hierarchical overview of the functionality of the designed planner and provide demonstrations with simulations. The practical part discusses results obtained from real flights of the vehicle.

Use of Astronomical Levelling for Creation of Quasigeoid Models
Jurčík, Josef ; Weigel,, Josef (referee) ; Machotka, Radovan (advisor)
My master´s thesis deals with use of astronomical levelling for creation of quasigeoid models. The basic input dates are componets of astronomical-geodetic deflections of the vertical in points, which are determined on AGNES and VEVEŘÍ nets. The dates are adjust for determination of relative quasigeoid. In literature [4], there is simplified solution for adjustment of this dates. The thesis looks for the most comprehensive solutions of adjustment without simplification. The solutions are compared.

Track's Elevation Profile View on a Public GIS
Doubal, Štěpán ; Šilhavá, Jana (referee) ; Fapšo, Michal (advisor)
This bachelor's thesis describes the design and implementation of a user script for GreaseMonkey (plug-in for Firefox). This script adds a functionality to show height profile of a defined route. The route is defined using public GIS tools from www.mapy.cz. The script extracts coordinates from page DOM structure, processes it and draws a height graph. The graph is created using http://www.heywhatsthat.com/profiler.html [2] or www.profile.hy.cz, which provides height graph drawing using www.vyskopis.cz JavaScript API [4].

Internal dynamics of Mars: a study based on gravitational and topographic data
Kalousová, Klára
In the present work we deal with the model of elastic lithosphere thickness on Mars. We assume that the surface load of the planet is compensated only by elastic lithosphere deflection and formulate the spatial inversion based on the comparison between predicted and observed geoid. Performing very extensive tests on this inversion in the two dimensional axisymmetric geometry we gain its best parameters. Then we invert the real data and construct the models of Martian elastic lithosphere thickness for filters of variable width. We focus on some topographically significant areas, establish the elastic lithosphere thickness below them and compare the obtained values with published results. For some areas we get agreement. Assigning the age to particular areas we find the growth of elastic lithosphere thickness during time, which is in agreement with the so-called principle of frozen lithosphere.
