1. GLONASS contributions to space geodesy
Sammanfattning : .... LÄS MER
2. Monitoring lithospheric motions by Satellite geodesy
Sammanfattning : Understanding of global and local Earth’s dynamic processes is of great importance to the Earth’s system knowledge, human life, and sustainability goals (e.g. climatic change and geo-hazard assessment, etc.). LÄS MER
3. Space Geodesy Techniques: An Experimental and Theoretical Study of Antenna Related Error Sources
Sammanfattning : This thesis presents work associated with antenna related error sources, as well as antenna design, in space geodesy utilizing the techniques of Very-Long-Baseline Interferometry (VLBI) and the Global Positioning System (GPS). Geodetic VLBI uses large radio telescopes, often in global networks observing at least a few times per year. LÄS MER
4. Simulation studies of new observing concepts for geodetic Very Long Baseline Interferometry
Sammanfattning : Very Long Baseline Interferometry (VLBI) is a space-geodetic technique in which observations are carried out simultaneously by radio telescopes separated by hundreds or thousands of kilometers. The time difference of signal reception between the telescopes is the basic observable used in geodetic VLBI. LÄS MER
5. Exploring Strategies for the Combination of Multiple Space-geodetic Techniques
Sammanfattning : Space-geodetic techniques are based on signal acquisition from extraterrestrial radio sources that can be used to infer geodetic positioning and define Earth-fixed and inertial reference systems. These techniques, which include Very Long Baseline Interferometry (VLBI) and Global Navigation Satellite Systems (GNSS) among others, exhibit different strengths and weaknesses in recovering parameters of interest.
