Estimation of Focal Length Variations of a 100-m Radio Telescope's Main Reflector by Laser Scanner Measurements
(2012-08)
Due to gravitation, the main reflector of a radio telescope underlies a deformation which causes
a change in focal length depending on the variations of the elevation angle of the telescope. In order
to estimate these ...
Modeling the Beam Deflection of a Gantry Crane under Load
(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 ...
Can we model the effect of observed sea level rise on tides?
(2018-06-07)
The link between secular changes in the lunar semidiurnal ocean tide (M2) and relative sea level rise is examined based on numerical tidal modeling and the analysis of long-term sea level records from Europe, Australia, ...
Development, Calibration and Evaluation of a Portable and Direct Georeferenced Laser Scanning System for Kinematic 3D Mapping
(2016-01-21)
In recent years, kinematic laser scanning has become increasingly popular because it offers many benefits compared to static laser scanning. The advantages include both saving of time in the georeferencing and a more ...
Analysis of Different Reference Plane Setups for the Calibration of a Mobile Laser Scanning System
(2017)
The discipline of engineering geodesy is currently subject to a paradigmatic change because the measuring of carefully selected single points is progressively replaced by an area-based acquisition of structures in form of ...
Dealing with systematic laser scanner errors due to misalignment at area-based deformation analyses
(2018-03-07)
The ability to acquire rapid, dense and high quality 3D data has made terrestrial laser scanners (TLS) a desirable instrument for tasks demanding a high geometrical accuracy, such as geodetic deformation analyses. However, ...
Brachflächenrevitalisierung im Rahmen der Flächenkreislaufwirtschaft
(2009)
In Deutschland wird eine nachhaltige Siedlungspolitik verfolgt, die einen sparsamen Umgang mit Grund und Boden in sozialverträglicher und ökologischer Flächennutzung vorsieht. Daher hat die Bundesregierung sich zur ...
Kommunales Kennzahlenmanagement am Beispiel von Vermessungs- und Katasterämtern in Nordrhein-Westfalen
(2008)
Seit Mitte der 1990er Jahre werden in den kommunalen Verwaltungen in Deutschland Maßnahmen zur Verwaltungsmodernisierung entwickelt. Kennzahlen nehmen dabei als Instrument der Steuerungsunterstützung eine Schlüsselfunktion ...
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, ...
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 ...
