The Gimbal with Mass Simulator was removed from the GGAO SGSLR facility in June 2022 and shipped back to Cobham. After the Factory Acceptance Test at Cobham in Lansdale, the Gimbal and Telescope Assembly (GTA) #1 was shipped to GGAO and installed in the SGSLR shelter in late June 2022. Preparations for the Site Acceptance Testing (SAT) were begun shortly after installation.
