Operational studies of the Onsala Twin Telescopes

Övrigt konferensbidrag, 2025

We present an overview of recent operational studies at the Onsala Space Observatory, focusing on the Onsala Twin Telescopes. The overview includes the so-called single-dish Tsys measurements covering the entire VGOS frequency band from 3 to 15 GHz, measurements with invar systems installed
in late 2023, monitoring pcal amplitudes and phases, and first test observations using potential future frequency setups for observations of the European Space Agency (ESA) Genesis satellite.
