| Summary: | Very Long Baseline Interferometry (VLBI) is a space geometric observing technique, the goal of which is to monitor the kinematics of interest points on Earth and in space. The observing instruments of VLBI are approximately 40 radio telescopes distributed throughout the world that simultaneously receive electromagnetic radiation emitted by compact objects in space, such as quasars. This technique has applications in geodesy, astrometry and astronomy (Nothnagel et.al., 2023). This master thesis aimed to analyze time series data from two of the northernmost VLBI telescopes, namely Nyales20 and Nyale13s, which are located in Svalbard, Norway. The thesis provided position time series data for both stations, which helped us to understand their position over the study period; to determine whether they exhibit discrepancies, especially in height biases; and finally, to analyze whether these changes could be related to factors such as glacier melting. Furthermore, this thesis evaluated the availability of sufficient ... |
