Astrometry and geodesy with Very Long Baseline Interferometry

The aim of my research is to provide accurate and stable spatiotemporal reference frames to society.

High-precision positioning, navigation, and timing are essential for daily life, scientific research, and space missions, all of which fundamentally depend on reliable spatiotemporal reference frames. Very Long Baseline Interferometry (VLBI) is a unique observing technique that measures the positions and motions of both celestial bodies and the Earth using radio telescopes. However, its accuracy is limited by atmosphere turbulence and other systematic errors. My research focuses on the modeling and mitigation of these error sources, based on existing and new, dedicated astrometric and geodetic VLBI observations, as well as self-developed analysis software.

Programme

Find out the research institutes that implement the Programme and where to find open positions.

Progress

Great start for the Programme! The first 36 postdoctoral researchers have been recruited and started their work. Half of them relocated to Finland from abroad.
