2nd International Conference on Machine Control & Guidance: proceedings ; March 9 - 11, 2010
(2010)
The importance of 3D-position sensors for the navigation of machinery on construction sites of roads, tunnels, railways, and airports has been steadily increasing over the last few years and the market
keeps growing. Also, ...
Simulated satellite formation flights for detecting the temporal variations of the Earth's gravity field
(2010)
In this thesis, the concept of satellite formation flight (SFF) is studied by means of simulated satellite observations. With various formation types enabling inter-satellite measurements in various directions
(e.g. ...
Möglichkeiten der Nutzung kinematischer Satellitenbahnen zur Bestimmung des Gravitationsfeldes der Erde
(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 ...
Proceedings of the 20th Meeting of the European VLBI Group for Geodesy and Astronomy: March 29-30, 2011
(2011)
On March 29 and 30, 2011, the European VLBI Group for Geodesy and Astronomy (EVGA) held its 20th meeting on the invitation of the Max Planck Institute for Radio Astronomy, Bonn, Germany. Starting
31 years ago on the ...
Zur Entwicklung und Bewertung der absoluten GNSS-Antennenkalibrierung im HF-Labor
(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 ...
Entwicklung eines Kalman-Filters zur Bestimmung kurzzeitiger Variationen des Erdschwerefeldes aus Daten der Satellitenmission GRACE
(2011)
Eine wichtige Beobachtungsgröße bei der Erforschung des Erdsystems stellt das Gravitationsfeld der Erde dar, dessen zeitliche Variationen mit der Satellitenmission GRACE (Gravity Recovery And Climate Experiment) erstmals ......

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 ...
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 ...
