Effects on the Geodetic-VLBI Observables Due to Polarization Leakage in the Receivers
(2011)
Geodetic VLBI delivers baseline length and Earth orientation parameter measurements, which offer the most viable and precise way to study Earth crustal and core dynamics and to support space navigation. The precision of ...
Separablity of deformations and measurements noises of GPS time series with modified Kalman filter for landslide monitoring in real-time
(2012)
The separation of the deformations and measurement noise of GPS coordinate time series and accuracy improvement of GPS real-time coordinates are major aspects of the thesis. In order to reduce the influence of the colored ...
Robust determination of station positions and Earth orientation parameters by VLBI intra-technique combination
(2011)
In this thesis, it is shown that combining contributions of different VLBI analysis centers, a so called intratechnique combination, improves the robustness and stability of the final VLBI results. For this purpose, a ...
Die Anerkennung und Feststellung von Grundstücksgrenzen: Ein Beitrag zur Entwicklung des Liegenschaftskatasters im Lande Nordrhein-Westfalen in Vergangenheit Gegenwart und Zukunft
(2012)
Das Eigentum am Grund und Boden wird im Grundbuch und im Liegenschaftskataster nachgewiesen und dokumentiert. Die aufgrund der historischen Entstehung und Entwicklung inhomogenen Nachweise des Liegenschaftskatasters sind ...
Ein Beitrag zur koordinatengesteuerten Aussaat von Rübenpflanzen mittels Multi-Sensor-System und Filteransatz
(2012)
Die Bestandspflege von landwirtschaftlichen Kulturen, maßgeblich geprägt durch die Unkrautkontrolle, wird heutzutage überwiegend mit chemischen Pflanzenschutzmitteln betrieben. Der gestiegene Bedarf an Bioprodukten erfordert ...
Vehicle Tracking and Motion Estimation Based on Stereo Vision Sequences
(2013)
In this dissertation, a novel approach for estimating trajectories of road vehicles such as cars, vans, or motorbikes, based on stereo image sequences is presented. Moving objects are detected and reliably tracked in ...
Development of a one-step 3D approach for the phase unwrapping process in a D-InSAR stack based on SBAS interferograms
(2020)
Differential Interferometric Synthetic Aperture Radar (D-InSAR) is a unique technique to detect and map deformations of the Earth's surface over large temporal and spatial scales. Processing a whole stack of multitemporal ...
Robot mapping and navigation in real-world environments
(2020)
Robots can perform various tasks, such as mapping hazardous sites, taking part in search-and-rescue scenarios, or delivering goods and people. Robots operating in the real world face many challenges on the way to the ...
Finding spectral features for the early indentification of biotic stress in plants
(2013)
Early detection of biotic stress in plants is vital for precision crop protection, but hard to achieve. Prediction of plant diseases or weeds at an early stage has significant influence on the extent and effectiveness of ...
Konsistente Kombination von Schwerefeld, Altimetrie und hydrographischen Daten zur Modellierung der dynamischen Ozeantopographie
(2012)
Die dynamische Ozeantopograpie als Differenz zwischen Meeresoberfläche und dem Geoid reflektiert charakteristische Merkmale der Ozeanzirkulation und stellt als gemessene Größe somit eine bedeutende Eingangsgröße in ...
