Modeling of inhomogeneous spatio-temporal signals by least squares collocation
Schuh, Wolf-Dieter; Korte, Johannes; Schubert, Till; Brockmann, Jan Martin (2022-06-16)Through inverse modeling and adjustment techniques, the geodesists try to derive mathematical models from their measurements to get a better understanding of various processes in the system Earth. Sophisticated deterministic ... -
Modeling the Beam Deflection of a Gantry Crane under Load
Holst, Christoph; Burghof, Martin; Kuhlmann, Heiner (2014-02)Gantry cranes load and unload containers from container ships. To ensure safety and operation, the deflection of their main beams under load should be analyzed. This deflection depends on the weight of the loaded container ... -
Möglichkeiten der Nutzung kinematischer Satellitenbahnen zur Bestimmung des Gravitationsfeldes der Erde
Löcher, Anno (2011)Die Extraktion von Schwerefeldinformation aus den Bahnverfolgungsdaten von Satelliten gehört zu den frühesten wissenschaftlichen Anwendungen der Weltraumtechnik. Die Ausrüstung von Satelliten mit GPSEmpfängern hat hier ... -
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 ... -
On high performance computing in geodesy: applications in global gravity field determination
Brockmann, Jan Martin (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 ... -
On Monte Carlo methods with applications to the current satellite gravity missions
Alkhatib, Hamza (2008)Large-scaled least squares problems require tailored numerical techniques to overcome the computational burden.For these types of problems iterative strategies are suitable because of their flexibility and effectiveness. ... -
On the theory and application of model misspecification tests in geodesy
Kargoll, Boris (2008)Many geodetic testing problems concerning parametric hypotheses may be formulated within the framework of testing linear constraints imposed on a linear Gauss-Markov model. Although geodetic standard tests for such problems ... -
Optimizing the Target-based Calibration Procedure of Terrestrial Laser Scanners: Optimierung des zielzeichenbasierten Kalibrierprozesses terrestrischer Laserscanner
Medić, Tomislav; Holst, Christoph; Kuhlmann, Heiner (2020)Terrestrial laser scanner (TLS) measurements suffer from systematic errors due to internal misalignments. The magnitude of the resulting errors in the point cloud exceeds the magnitude of random errors in many applications. ... -
Overview on Current Modelling Strategies of Point Clouds for Deformation Analysis: Überblick aktueller Methoden zur Modellierung von Punktwolken für die Deformationsanalyse
Neuner, Hans; Holst, Christoph; Kuhlmann, Heiner (2016)Terrestrial laser scanning was used for deformation monitoring of structures and geoscientific objects already at an early stage of its employment for engineering geodetic tasks. This paper gives an overview on current ... -
