Highlights
We are pleased to announce that the 24th International Workshop on Laser Ranging (IWLR) will take place in Buenos Aires, Argentina the week of November 1-6, 2026. An SLR school will take place on Sunday, November 1st, followed by the Workshop Monday through Friday. An excursion to the AGGO observatory is scheduled for Thursday afternoon of November 5, 2026. Please note that the meeting is planned as a face-to-face (in person) event.
More information is available at the meeting website, which is as follows: https://bkg.bund.de/en/bkg/events/ilrs-workshop
On the website you will find information about the workshop, including registration fees, venue, conference dinner, accommodations, SLR school, and more. Registration will open soon, followed by abstract submissions. Please note that the website is still under construction in some places. [Some may find it expedient to use a browser other than Firefox, if they encounter certificate issues].
The Workshop is hosted by BKG (Bundesamt für Kartographie und Geodäsie - Federal Agency for Cartography and Geodesy), AGGO (Argentine German Geodetic Observatory), CONICET (the Argentine National Scientific and Technical Research Council), and the National Technical University (Universidad Tecnológica Nacional – UTN).
More information about the workshop topics and sessions will be communicated soon.
Special note regarding travel to Buenos Aires during the IWLR:
During the week of the 2026 IWLR meeting and the weeks surrounding the IWLR meeting, the main international airport in Buenos Aires (EZE, Ezeiza International Airport) will be undertaking runway maintenance on their #2 runway, which will close that runway and also reduce the length of the primary runway by a significant amount. As a result, wide-body jets (e.g. Airbus A330, Boeing 777, Airbus A350, Boeing 747) will not be able to take off from EZE at full capacity during that period.
With a couple exceptions, this means that travel to/from Buenos Aires from outside South America will require a stopover somewhere in South America, prior to continuing onward to Buenos Aires on a medium-body aircraft (e.g. Airbus A320/A321, Boeing 737/757). (These stopover airports may be São Paulo, Santiago, Bogota, Rio de Janeiro, Montevideo, etc.). Travelers should make sure they allocate sufficient time (3-4 hrs) to make a transfer at these airports. Onward connection flights are then available to both EZE (Ezeiza International Airport) and to AEP (Aeroparque Jorge Newberry), the two airports near Buenos Aires that serve international, regional and domestic traffic. Please consult with a travel advisor or your airline for more information.
