Determination of sub-daily earth rotation parameters from VLBI observations
Artz, Thomas (2015)The work presented deals with the determination of sub-daily Earth Rotation Parameters (ERPs) from Very Long Baseline Interferometry (VLBI) observations. Monitoring and interpreting the Earth's rotation variations in general ... -
A new approach for a kinematic-dynamic determination of low satellite orbits based on GNSS observations
Shabanloui, Akbar (2008)A new approach for the integrated kinematical-dynamical orbit determination of low flying satellites based on high-low GPS-SST observations is proposed. These observations are code and carrier phase measurements between ... -
Retrieval of sea level and surface loading variations from geodetic observations and model simulations: an integrated approach
Rietbroek, Roelof (2015)The mass distribution in the system Earth changes dynamically over time. Time-variable mass transport mainly arises from the interplay between the terrestrial hydrological water cycle, the ocean and atmosphere, and the ... -
Separablity of deformations and measurements noises of GPS time series with modified Kalman filter for landslide monitoring in real-time
Li, Lihua (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 ... -
Visual SLAM from image sequences acquired by unmanned aerial vehicles
Steffen, Richard (2013)This thesis shows that Kalman filter based approaches are sufficient for the task of simultaneous localization and mapping from image sequences acquired by unmanned aerial vehicles. Using solely direction measurements to ... -
Zur Entwicklung und Bewertung der absoluten GNSS-Antennenkalibrierung im HF-Labor
Zeimetz, Philipp (2011)Bei der relativen Positionsbestimmung mit GNSS-Verfahren stellen die Antenneneinflüsse, die sich durch eine richtungsabhängige Empfangscharakteristik auszeichnen, einen der die Genauigkeit begrenzenden Faktoren dar. Durch ...
