Improved area-based deformation analysis of a radio telescope’s main reflector based on terrestrial laser scanning
(2015-03-14)
The main reflectors of radio telescopes deform due to gravitation when changing their elevation angle. This can be analyzed by scanning the paraboloid surface with a terrestrial laser scanner and by determining focal length ...
On high performance computing in geodesy: applications in global gravity field determination
(2015)
Autonomously working sensor platforms deliver an increasing amount of precise data sets, which are often usable in geodetic applications. Due to the volume and quality, models determined from the data can be parameterized ...
Retrieval of sea level and surface loading variations from geodetic observations and model simulations: an integrated approach
(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 ...
The application of impact factors to scheduling VLBI Intensive sessions with twin telescopes
(2015)
This thesis deals with the scheduling of special purpose, 1h-long VLBI sessions, so-called Intensives, and its further extension by twin radio telescopes. The daily VLBI Intensive measurements make an important contribution ...
Determination of sub-daily earth rotation parameters from VLBI observations
(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 ...
Analyse der Konfiguration bei der Approximation ungleichmäßig abgetasteter Oberflächen auf Basis von Nivellements und terrestrischen Laserscans
(2015)
Seit einigen Jahren unterliegt der Bereich der Ingenieurgeodäsie einem starken Wandel, da sich diese Disziplin generell den stetig weiterentwickelnden, anwendungsbezogenen Problemstellungen widmet. Unter diesen Aspekten ...
Convex optimization for inequality constrained adjustment problems
(2015)
Whenever a certain function shall be minimized (e.g., a sum of squared residuals) or maximized (e.g., profit) optimization methods are applied. If in addition prior knowledge about some of the parameters can be expressed ...
