22^nd International Workshop on Laser Ranging (IWLR) in Guadalajara, Spain - November 7-11, 2022 - Session Videos Available for viewingRelease Date: 03/03/2023

We are pleased to announce that the recordings for the 22^nd International Workshop on Laser Ranging (IWLR) held in Guadalajara, Spain, are available for viewing. This is the first time that a full ILRS workshop is made available in video. This, together with the ILRS Virtual World Tours 2020 and 2021, all the events organized by the ILRS in the last three years are publicly accessible to everyone.

The 22^nd IWLR was organized by the Observatory of Yebes, the National Geographic Institute of Spain (IGN/CNIG), and the ILRS. Over 170 delegates from 20 different countries participated in the conference, which took place on 7–11 November 2022. With the theme "Reconnecting the ILRS community", this event was for the first time in a hybrid in person/online format. The conference was a great opportunity for the experts in the various SLR-related fields to meet, discuss, and exchange ideas and new developments.

The video recordings of the conference include the talks from all the 10 Main Sessions; the presentations kindly given by the invited speakers; and the meetings of the ILRS Standing Committees on Data Formats & Proceedings, Networks & Engineering, and Missions. The Opening and Closing sessions, including the SLR Pioneers Awards, are all available for viewing as well.

We thank the Local Organizing Committee for making and sharing the recordings of the conference possible.

22^nd International Workshop on Laser Ranging (IWLR): Reconnecting the ILRS CommunityRelease Date: 12/02/2022

The 22^nd 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.
