A new jackscrew and gearbox assembly were installed on the 12m VGOS antenna system at NASA Goddard Geophysical Astronomical Observatory (GGAO) in Greenbelt, Maryland during the week of June 6 – 10, 2022. The GGAO site operations and engineering management team from Peraton, antenna repair technicians from Intertronics Solutions, Inc. (ISI) – Calian and heavy equipment operations personnel from United Rigging in Beltsville, Maryland supported the repair activities. Replacement of the jackscrew improves overall structural and motion integrity associated with antenna pointing requirements and promotes continuous VLBI scientific research contributions from the NASA/SGP network.
