Van de Brekel, B.J.H. (author)Multipath effects form a serious threat to high precision GPS and DGPS applications. The errors caused by multipath can have values of more than 100 meters. This paper shows that when a rotating antenna is used in stead of a stationary one, the multipath errors can be mitigated to great effect, both for carrier phase and code range errors. The...master thesis 1992

Eijkman, M.T. (author)In het Global Positioning System (GPS) wordt de positie berekend door de afstanden tot satellieten te bepalen uit de vertragingstijd van de uitgezonden signalen.<br/> Er kunnen echter grote fouten in de positiebepaling ontstaan wanneer de signalen niet alleen rechtstreeks worden ontvangen, maar ook gereflecteerd (multipath). Om dit ...master thesis 1995

Septiawan, R. (author)De satellieten van het Global Positioning System bevinden zich op 20.000 km boven het aardoppervlak. Het navigatie signaal van deze satellieten is heel zwak bij de ontvanger van de gebruikers. Daardoor is dit signaal makkelijk te verstoren door een interferentiebron. In mijn afstudeeropdracht wordt onderzoek gedaan om deze interferentie te...master thesis 1995

Hartlieb, E.S. (author)Proceeding a short overview of the Navigation simulation (NAVSIM) within the SIMONA research simulator, a detailed description of NAVSIM will be given. For NAVSIM, a modular schematic has been developed. The models of the navigation system must comply to this schematic. In this report, the following radionavigation systems will be discussed: VOR...master thesis 1995

Van 't Geloof, J. (author)Currently a debate is in progress concerning the technical capabilities of the Global Positioning System, to provide the primary aid for precision approach and landing of airplanes. The signal levels of the received satellite signals are very low because of the propagation distance of about 20000 km. GPS receivers are, therefore, susceptible to...master thesis 1995

De Bruijn, R.E. (author)At present, the GPS position sensor requirements are lower than the requirements that have to be met when using perspective flightpath displays. Besides the GPS position sensor requirements, data latency, data update rate, and display update rate, could cause the display presentation system not to meet all the requirements. As a result,...master thesis 1999

(author)There are currently three active projects under development for the Delfland coast, all aiming at reinforcing the coast. The main issue is where to put the sand such that it arrives at the coast in the best place, without causing any damage to e.g. the new nature development. To answer this question, knowledge about sand transport is necessary,...student report 2008

Klein Haneveld, B.A. (author), Ulgen, U. (author)With the development of 3G technology information is getting more and more accessible. While being very practical this availability of information can have adverse effects on people. The research shows that some people on their leisure time enjoy and value uncertainty. A literature and user research revealed that people with certain personality...bachelor thesis 2009

Stam, J. (author)With the advent of Unmanned Aerial Vehicles, it becomes possible to use these vehicles to acquire photogrammetric images in a more cheap and flexible way compared with conventional photogrammetry from a full-sized airplane. A big factor in costs and resources in conventional photogrammetry is signalling and measuring ground control points, which...master thesis 2011

Hummelink, B.A. (author)Today, there is an increase in the use of Unmanned Aerial Vehicles (UAV's), for applications that can be considered dull, dirty or dangerous when compared to those applications of conventional aircraft or helicopters. To further increase the use of UAV's, their navigation filters must be robust and reliable. The trend in current autopilot...master thesis 2011

Pauwels, G.J.J.M. (author)In this report a high accuracy positioning system is investigated for use in the Superbus. The Superbus project is an effort to apply a new and complete conceptual approach to public transport. It consists of a vehicle, logistics and infrastructure. The positioning system for the vehicle is to have a horizontal position error, which will not...master thesis 2011

Van Langelaar, C.M. (author)We all have walked on a street when suddenly someone comes over to you asking for directions. Sometimes, people do not know where they are and they do not know how to reach their destination. They are lost. However, people should not depend on others to find their way. The urban fabric should be legible enough to find one’s way. The problem...master thesis 2011

Meijer, A.M. (author)Probe data from consumer GPS navigation devices provides a network-wide and cost-efficient data source for measuring vehicle movements. The measurement of traffic volume, route choice and delay on intersections is needed for efficient intersection control. Data collection from road-side sensors can provide this information but is expensive and...master thesis 2011

Jongkind, E. (author)Water vapour in the atmosphere is a key variable in the prediction of heavy rain and thunderstorms. Water vapour in the atmosphere is still badly modeled although more and more ground based, airborne, as well as spaceborne measurements are retrieved. The main input for current water vapour maps are Integrated Water Vapour (IWV) measurements...master thesis 2011

Valk, M. (author)In this paper I present a novel method to determine the time of occurrence of tidal slack with a GPS receiver mounted on an anchored buoy commonly used to delineate shipping lanes in estuaries and tidal channels. Slack tide occurs when the tide changes direction from ebb to flood flow, or from flood to ebb. The determination of this point in...master thesis 2012

Van der Spek, I.T. (author), Voorsluys, M.H. (author)In this thesis first a study is conducted on which position determination method should be used in a UAV and especially in the Parrot AR.Drone. Then an autonomous control for the AR.Drone is designed. The best position determination method in this case appeared to be a combination of a GPS sensor and a barometer. The autonomous control is...bachelor thesis 2012

Van der Kruk, E. (author)Ice-skating is a rather special form of locomotion: the skater pushes sideward to propel himself forward; Insight in the details of this technique can help a speed skater improve his performance. The aim of this thesis is to develop a reliable and valid three-dimensional biomechanical model that simulates the motion of a speed skater, to gain...master thesis 2013
