Abstract

The GRAVITY+ project encompasses the upgrade of the Very Large Telescope Interferometer infrastructure and of the GRAVITY instrument to improve sky coverage, high-contrast capabilities, and faint science. The sky coverage is obtained by the use of one laser guide star on each Unit Telescope, but it first required an upgrade of the infrastructure of the telescopes, carried out over the last 18 months.
