ILRS Virtual World Tour 2021

ILRS, 📅 Event Update
Due to the COVID 19, we have had to postpone our laser workshops, our annual seminal events, in 2020 and 2021. The ILRS again wishes to provide the opportunity for our worldwide community to meet, at least virtually, and share. Following the success of the Virtual World Tour last year, we will hold another Virtual World Tour between October 25-29, 2021, to virtually visit 5 stations in 5 days, stopping at Herstmonceux (UK), Wetzell (DE), Mendeleevo (RU), Shanghai (PRC), Monument Peak (USA).

Satellite Laser Ranging School

ILRS, 📅 Event Update
Prior to the 2019 ILRS Workshop, the ILRS scheduled a one-day introductory course to give non-practitioners in SLR an opportunity to broaden their knowledge about laser ranging to Earth-orbiting satellites and the Moon. The course also provided attendees with some experience in the field an opportunity to refresh and strengthen their knowledge and increase their appreciation of this powerful measurement technique that supports geoscience and applications.
