A new approach for a kinematic-dynamic determination of low satellite orbits based on GNSS observations
(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 ...
Gravity field refinement by radial basis functions from in-situ satellite data
(2008)
In this thesis, an integrated approach is developed for the regional refinement of global gravity field solutions. The analysis concepts are tailored to the in-situ type character of the observations provided by the new ...
Singular Value Decomposition and Cluster Analysis as Regression Diagnostics Tools in Geodetic VLBI
(2008)
It is well known that high-leverage observations significantly affect the estimation of parameters. So far, mainly redundancy numbers have been used for the detection of single high-leverage observations or of single ...
Geodäsie und Quantenphysik
(2007)
Im Jahr 1880 äußerte HELMERT fest, "Geodäsie ist die Wissenschaft von der Ausmessung und Abbildung der Erdoberfläche". Mit diesem Zitat werden viele geodätische Arbeiten begonnen, und auch für den vorliegenden Beitrag ...
Grouping Uncertain Oriented Projective Geometric Entities with Application to Automatic Building Reconstruction
(2007)
The fully automatic reconstruction of 3d scenes from a set of 2d images has always been a key issue in photogrammetry and computer vision and has not been solved satisfactory so far. Most of the current approaches match ...
The use of topographic isostatic mass information in geodetic applications
(2008)
The gravity field effects of the topographic-isostatic masses represent an important information of the high-frequent part of the gravity field. In this work the physical-mathematical basics of the classical topographic-isostatic ...
Gravitationsfeldbestimmung aus der Analyse kurzer Bahnbögen am Beispiel der Satellitenmissionen CHAMP und GRACE
(2008)
In dieser Arbeit werden verschiedene Modellansätze für die Auswertung von SST-Beobachtungen zur Gravitationsfeldbestimmung vorgestellt, die besonders auf Satellitenmissionen wie CHAMP und GRACE abgestimmt sind. Das heißt, ...
On the theory and application of model misspecification tests in geodesy
(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 ...
On Monte Carlo methods with applications to the current satellite gravity missions
(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. ...
