Zur Entwicklung und Bewertung der absoluten GNSS-Antennenkalibrierung im HF-Labor
(2010-07-09)
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 ...
Visual SLAM from image sequences acquired by unmanned aerial vehicles
(2009-12-08)
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 ...
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 ...
Retrieval of Sea Level and Surface Loading Variations from Geodetic Observations and Model Simulations: an Integrated Approach
(2014-04-07)
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 ...
Estimation of Very long Base Lines by GPS -Geodesy for Indian Plate Kinematic Studies
(1999)
Under the Indo-German Collaborative, Bilateral Exchange Programme, a Project to study the ongoing Indian plate motion has been initiated between the National Geophysical Research Institute (NGRI, CSIR) and the Geodetic ...
