The Cherenkov Telescope Array Observatory is an international user facility distributed over four primary sites: Headquarters (Bologna, Italy), Science Data Management Centre (Zeuthen, Germany) and two array sites located in the northern (Observatorio del Roque de los Muchachos (ORM), La Palma, Spain) and southern hemispheres (between Cerro Paranal and Cerro Armazones ESO observatories in Chile).

The Cherenkov Telescope Arrays consist in many tens of telescopes for Gamma Ray observation, divided in three configurations, in order to cover the energy range from a tens of GeV (Large Sized Telescope, LST), to a tens of TeV (Medium Sized Telescope, MST), and up to 100 TeV (Small Sized Telescope, SST). The LST is an alt-azimuth telescope which have in a primary mirror of 23 m diameter and 28 m focal length; a larger mirror and higher photo detection efficiency allow to detect smaller atmospheric showers
Under the CTA+ initiative, which is funded through the PNRR program, INAF is responsible for the design, fabrication, and testing of the Large Sized Telescopes located in the southern hemisphere, specifically in the valley between Paranal and Armazones.

Arpsoft has been assisting the INAF project office since the initial stages of the project, offering consultancy services for project management and system engineering tasks.
