This is a two day meeting, focusing on each of the key topics. Invited talks of 20 minutes and contributed talks of 12 minutes are foreseen, both including time for discussion. In addition a 30 minute review talk will be scheduled in which an overview of the field of modern astrometry and its science applications will be given. There will also be a 30 minute slot for poster presentations.

2022.06.01 There are still talk slots open for remote or in-room contributions. Contact the SOC if you are interested.
