The 22nd International Workshop on Laser Ranging took place in Guadalajara, Spain, November 7-11, 2022, hosted by the Yebes Observatory, the National Geographic Institute of Spain (IGN), with the support of National Centre for Geographic Information (CNIG), and in collaboration with the International Laser Ranging Service (ILRS). Being the first in-person ILRS meeting since the start of the COVID-19 pandemic, the theme of the meeting was "Reconnecting the ILRS community". In person and online attendees participated in an exciting program, which included sessions on ILRS Contributions to Earth Orientation Parameters (EOP); Laser Ranging Applications to Precision Orbit Determination (POD); Science Applications of Satellite Laser Ranging (SLR); Errors in SLR detection, mitigation, and modeling; Current and Future Missions; Ground Networks and Operations; Space Debris, Technology and Developments, and New Applications; and Lunar Laser Ranging and Deep Space. Participation in the workshop included 170 delegates from 20 different countries, and approximately 30-40 persons attending online each day from throughout the world, with 77 oral talks and 32 posters presented. Invited talks were given by Dr. Nick Brown (Geosciences Australia), Dr. Pablo de Vicente (Yebes Observatory, IGN/CNIG, Spain), Dr. Rüdiger Haas (University of Technology, Onsala Space Observatory, Sweden), and Dr. Tim Flohrer (ESOC, European Space Agency). The program included a visit to Yebes Observatory with a tour of the facilities, including the new Satellite Laser Ranging (SLR) station at Yebes, set to become operational in 2023. Ron Noomen (TU Delft, The Netherlands), Jean-Marie Torre (Observatoire de la Côte d'Azur, France) and Graham Appleby (Herstmonceux Geodetic Observatory, U.K.) were presented with ILRS Pioneer Awards. Stephen Merkowitz (NASA Goddard Space Flight Center, U.S.A.) was elected as the Chairperson of the ILRS Governing Board (GB) for the period 2023-2024.

Splinter meetings for the ILRS Governing Board, Analysis, Missions, Networks and Engineering Special Committees, the Transponders & Lunar Laser Ranging and Space Debris Study Groups were also held, and reports presented.

BKG and TUM jointly celebrated their 50 years milestone on 7 Oct 2022, with about 100 attendees from Germany and foreign countries. A series of welcome notes and talks were presented by the hosts, the local politicians, government representatives and the IAG Services. Congratulations!
