REFAG 2022 – Symposium on Reference Frames for Applications in Geoscience
The REFAG 2022 carries on the tradition of previous IAG dedicated symposia on Reference Frames, aiming to bring together leading experts from academia, public authorities and private sector with young scientists and students, to discuss current achievements and future prospects of geodetic reference frames and their scientific and societal impact. Don't miss to participate in this great symposium.

REFAG 2022 – Call for papers
IAG International Symposium on Reference Frames for Applications in Geosciences (REFAG 2022), Thessaloniki, Greece, October 17-20, 2022

Tour de l’IGS
The Tour de l’IGS is a series of virtual workshops on relevant topics to the IGS membership, stakeholders and GNSS community in general. These events will be hosted several times a year and will cover a wide range of topics including space-borne and ground-based instrumentation, technology development, scientific and societal applications, etc.

X. Hotine-Marussi Symposium
The jubillee X Hotine-Marussi Symposium will be organized at the Politechnico di Milano, Italy on June 12-17, 2022. See the first crcular for more details!

ILRS Virtual World Tour 2021
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).

IAG SA manuscript submission to the IAG Symposia Series
The portal for submitting papers for the IAG2021 volume of the IAG Symposia Series is now open. Paper submission will be open until September 30, but we will start the peer review of papers as soon as they are submitted. All papers that are accepted will be available online after acceptance.

Satellite Laser Ranging School
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.

Report on the ILRS Technical Workshop 2019
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.
