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.

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).

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.

NASA, Norway to Develop Arctic Laser-Ranging Station
NASA and the Norwegian Mapping Authority are partnering to develop a state-of-the-art satellite laser ranging station 650 miles from the North Pole that will produce high-precision locations of orbiting satellites, help track changes in the ice sheets and improve the efficiency of marine transportation and agriculture.

Inauguration of the Onsala Twin Telescopes
The Onsala Space Observatory, Chalmers University of Technology, and the International VLBI Service for Geodesy and Astrometry (IVS) are proud to announce the ceremonial inauguration of a new pair of Twin Telescopes for geodetic and astrometric VLBI. More than 200 international and national guests, including veterans of the first transatlantic VLBI observations in 1968 as well as the regional governors and representatives of Chalmers, participated in the festivity on Thursday, 18 May 2017.
