1. Geodetic analysis for the Very Long Baseline Interferometry Global Observing System
Sammanfattning : Very Long Baseline Interferometry (VLBI) is an essential technique forspace-geodesy. It realizes the International Celestial Reference Frame(ICRF) and provides a link between the Earth- and space-fixed coordinatesystems by directly observing all Earth Orientation Parameters (EOP)simultaneously. LÄS MER
2. 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
3. Observation strategies for current and future geodetic very long baseline interferometry
Sammanfattning : Geodetic Very Long Baseline Interferometry (VLBI) is an essential technique for space geodesy. It is uniquely capable of simultaneously observing all Earth Orientation Parameters (EOP) and directly giving access to the Earth’s rotation angle (related to Universal Time, UT1). LÄS MER
