ILRS Virtual World Tour 2020 second circular
09/25/2020
ILRS logoIn place of the planned Workshop this November, the ILRS wanted to take the opportunity to try something different and look in detail at a selection of stations in the global network. The online 'Virtual World Tour', to be held November 2-6, 2020, will visit 5 stations in 5 days, stopping at:

  • Graz, Austria
  • Greenbelt MD, USA
  • Simosato, Japan
  • Yarragadee, Australia
  • Zimmerwald, Switzerland

Each two-hour session will consist of an introductory presentation about the station followed by a tour of the site highlighting instrumentation, software, safety, automation, operations, as well as current issues and future plans. These tours will include a mixture of pre-recorded and live presentations with an opportunity for questions.

More information about the workshop can be found on the website:

https://cddis.nasa.gov/ILRS_Virtual_World_Tour_2020/index.html

and in the second circular.

Passing of Ron Beard/NRL
07/22/2020
photo of Ron BeardWe are sad to report the recent passing of Ron Beard. Ron Beard was the past Head of the Advanced Space PNT Branch (formerly the Space Applications Branch) at the Naval Research Laboratory (NRL) where he has made significant contributions to the generation and dissemination of precise time from space over the course of his 50-year career.

Mr. Beard joined the Navy and later NRL as the DoD was beginning to explore new concepts for a second-generation satellite-based navigation system. At NRL he worked for Roger Easton, who proposed "passive ranging" from satellites with synchronized clocks in what became the TIMATION project. There was very limited experience with precise clocks in the space environment during those early days.

ILRS Workshops scheduled for 2020 and 2021 postponed
07/14/2020
ILRS logoAs the ILRS community continues to deal with the impacts from the global coronavirus outbreak, the ILRS and the local organizers in Kunming have concluded that it is no longer possible to hold the 22nd International Workshop on Laser Ranging in October 2020 as planned. The ILRS Governing Board, in consultation with our colleagues in Kunming, has decided that we will delay this workshop until the fall of 2021; final dates for the event will be announced soon. Furthermore, the ILRS and UNSA will postpone the next ILRS Technical/Specialty Workshop, to be held in Arequipa Peru, until the fall of 2022.

We will keep the community informed of additional details as soon as practical.

Ny-Ålesund SGSLR dome passes Factory Acceptance Testing
07/02/2020
ILRS logoSGSLR's third dome, built for Ny-Ålesund, Norway, successfully passed the Factory Acceptance Test (FAT) at Baader Planetarium in Mammendorf Germany on 2 July 2020. Jan McGarry (NASA) and KBR team members, including Scott Wetzel and Howard Donovan, attended the FAT virtually. KBR approved the FAT and accepted the dome. Installation of the dome at Ny-Ålesund is expected to occur in September 2020.

2021 ILRS Technical/Specialty Workshop
04/02/2020
ILRS logoThe ILRS Governing Board is pleased to announce that the 2021 ILRS Technical/Specialty Workshop will be held in the October 2021 timeframe in Arequipa, Peru. The workshop will be hosted by the Astronomical and Aerospace Institute at the University of San Agustin.

At this time, the ILRS continues planning for the 22nd International Workshop on Laser Ranging in November 2020 with the local hosts in Kunming, China.
