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.
This year’s International Laser Ranging Service (ILRS) Technical Workshop was hosted by German Aerospace Center (DLR) in Stuttgart, Germany, from October 21st to 25th. Following the motto “Laser ranging: To improve economy, performance, and adoption for new applications” the presentations were focused on the technical challenges for the satellite laser ranging (SLR) ground segment.
