Geers, M.A. (author)The European Student Earth Orbiter (ESEO) is the main educational project of the European Space Agency that allows students to design, develop and test scientific payloads. The contribution to be made by the TU Delft is a software-based Attitude Determination Experiment (ADE) that contains four different algorithms for attitude estimation that...master thesis 2016

Srongprapa, P. (author)A geostationary transfer orbit (GTO) is typically used to inject spacecraft into the geosta- tionary orbit. There are many inoperative launcher upper stages and other fragments or- biting in GTOs. These parts collide and disintegrate, becoming even smaller fragments and thereby worsening the problem of space debris. The objects could also...master thesis 2015

Mani, K.V. (author)Robust turbulence modelling of cavitating flows is essential for physically accurate predictions of the performance characteristics of cryogenic rocket turbo-pump inducers. Numerical modelling of such flows complement experiments and are comparatively inexpensive, but they lack accurate predictive capabilities. This work focuses on the...master thesis 2015

Holtkamp, G.C. (author)This report deals with the design of a complete guidance, navigation and control system for a planetary lander on Enceladus, for both descent and repositioning. A basic lander model with a main engine, attitude thrusters and a landing gear is presented, for which the equations of motion in different reference frames are derived, including the...master thesis 2014

Noroozi, A. (author)The trend of space technology developments is moving from high power consuming, bulky and costly systems towards low-power, small, low-cost and flexible systems. Thus, the spacecraft can benefit from multi-purpose and flexible systems which can be low-power and low-cost by employing new technology. One example of such system is a GNSS receiver...doctoral thesis 2013

Kuiper, J.M. (author)Mass-spring and liquid dampers enable structural vibration control to attenuate single, coupled lateral and torsional vibrations in diverse structures. Out of these, the passively tuned liquid damper (TLD) class is wanted due to its broad applicability, extreme reliability, robustness, long life time and ease of manufacturability. In this PhD...doctoral thesis 2012

Van der Ham, L. (author)Instead of the two-body problem commonly used in interplanetary trajectory design, also three bodies can be considered: the satellite, a planet and the Sun. Knowing that planet and Sun orbit one another in almost circular orbits, and the mass of the satellite is negligible compared to the mass of these bodies, the model of the circular...master thesis 2012

Giorgi, G. (author)Attitude determination through the use of Global Navigation Satellite System (GNSS) signals is one of the many applications of satellite-based navigation. Multiple GNSS antennas installed on a given platform are used to provide orientation estimates, thus adding attitude information to the standard positioning service. Precise attitude estimates...doctoral thesis 2011

(author), Van der Marel, H. (author), Van Bree, R. (author), Altena, B. (author), Martín-Neira, M. (author)The Global Navigation Satellite System Reflectometry (GNSS-R) concept was conceived as a means to densify radar altimeter measurements of the sea surface. Until now, the GNSS-R concept relied on open access to GNSS transmitted codes. Recently, it has been proposed that the ranging capability of the technique for ocean altimetric applications can...journal article 2011

Van Goor, B. (author)A Terrestrial Laser Scanner (TLS) is a powerful tool for surveying. Tens of millions of points are acquired with a high accuracy and within a short time. The resulting point clouds can be used to find changes and deformations. For this project, four point clouds of the metro station and tunnel at Rotterdam central station are available. The...master thesis 2011

D'Amico, S. (author)Formation flying is commonly identified as the collective usage of two or more cooperative spacecraft to exercise the function of a single monolithic virtual instrument. The distribution of tasks and payloads among fleets of coordinated smaller satellites offers the possibility to overcome the classical limitations of traditional single...doctoral thesis 2010

Soudarissanane, S. (author), Lindenbergh, R. (author), Menenti, M. (author), Teunissen, P.J.G. (author)A terrestrial laser scanner measures the distance to an object with a precision in the order of millimeters. The quality of each single point in a point cloud affects post-processing applications, such as deformation analysis or 3D modeling. The quality of a scan point is influenced by four major factors: instrument calibration, atmospheric...conference paper 2009

Bucksch, A. (author), Lindenbergh, R. (author), Mementi, M. (author), Raman, M.Z. (author)New airborne LiDAR (Light Detection and Ranging) measurement systems, like the FLI-MAP 400 System, make it possible to obtain high density data containing far more information about single objects, like trees, than traditional airborne laser systems. Therefore, it becomes feasible to analyze geometric properties of trees on the individual object...conference paper 2009

De Ridder, S. (author)The unpowered entry of a winged re-entry vehicle, such as the HORUS-2B, consists of a hypersonic atmospheric re-entry phase, a Terminal Area Energy Management (TAEM) phase and a approach and landing phase. The TAEM is the subject of this thesis study. During the TAEM, the vehicle is brought to the correct interface position with the landing...master thesis 2009

(author)In this study, we present a comparison of coincident GRACE and ICESat data over Antarctica. The analysis focused on the secular changes over a 4-year period spanning from 2003 to 2007, using the recently reprocessed and publicly available data sets for both missions. The results show that the two independent data sets possess strong spatial...journal article 2009
