When working on this project, I quickly realized I had to go out and get a feel for what the materials of this mysterious VLBI is. The Mapping Authority has an antenna in Ny-Ålesund (Svalbard) and I went there to learn more about VLBI, the signal from the stars and how it is used.
As Svalbard is such a spectacular site, I have made some extra documentation of the trip there.
Observation antennas in the arctic contribute greatly to the worldwide VLBI network, both due to high visibility (more visible stars, and they stay up longer) and due to the extremely clean and noise free environmental conditions. During this research trip I’ve been warmly welcomed and helped by the crew in Ny-Ålesund led by Moritz Sieber.
