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 ...
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 ...
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 ...
The application of impact factors to scheduling VLBI Intensive sessions with twin telescopes
(2015)
This thesis deals with the scheduling of special purpose, 1h-long VLBI sessions, so-called Intensives, and its further extension by twin radio telescopes. The daily VLBI Intensive measurements make an important contribution ...
Determination of sub-daily earth rotation parameters from VLBI observations
(2015)
The work presented deals with the determination of sub-daily Earth Rotation Parameters (ERPs) from Very Long Baseline Interferometry (VLBI) observations. Monitoring and interpreting the Earth's rotation variations in general ...
Atmospheric refraction and turbulence in VLBI data analysis
(2018)
The progress in further improving the quality of results derived by space-geodetic techniques observing in the radio frequency domain, such as Very Long Baseline Interferometry (VLBI) or Global Navigation Satellite Systems ...
