Magnetic Field Sensor Calibration for Attitude Determination
(2014-05-29)
The presented work aims to give an overview of different calibration methods for magnetic field sensors,
which are used for attitude determination. These methods are applicable in the field without any additional equipment. ...
Investigations on the Influence of Antenna Near-field Effects and Satellite Obstruction on the Uncertainty of GNSS-based Distance Measurements
(2016-03-31)
Antenna near-field effects are one of the accuracy
limiting factors on GNSS-based distance measurements.
In order to analyse these influences, a measurement campaign
at an EDM calibration baseline site with optimum
GNSS ...
Entwicklung einer direkten Georeferenzierungseinheit zur Positionsund Orientierungsbestimmung leichter UAVs in Echtzeit
(2016)
Seit einigen Jahren werden im Bereich der Geodäsie immer häufiger auch Unmanned Aerial Vehicles (UAVs) als kinematische Trägerplattformen eingesetzt. Dazu werden diese mit objekterfassender Sensorik, wie z.B. Digitalkameras ...
Direct Georeferencing for Portable Mapping Systems: In the Air and on the Ground
(2017-11)
During the last few years, the acquisition of geometric information about objects by using a moving sensor platform has gained increasing popularity in the surveying community. A large number of companies offer vehicle-based ...
Automatic optimization of height network configurations for detection of surface deformations
(2013-05-18)
Levellings are performed to observe height changes of different epochs at discrete surveying points. A
reliable estimation of surface deformations by a bivariate polynomial needs a sufficient configuration of the underlying ...
