Abstract
The Sardinia Radio Telescope performance upgrade is completed and now it has the capabilities to scan the universe up to a maximum radio frequency of 116 GHz, corresponding to a wavelength of 2.6mm. Nevertheless, observing at the highest frequencies for which SRT has been designed, requires a tighter control of the pointing and main reflector surface accuracy than before. This is possible through the mitigation of effects produced by environmental loads that were previously negligible. Therefore, a new metrology system, called SMS, has been implemented to face the new challenges. This paper aims to provide a description of strategies conceived to use the SMS system instrumentation, in order to achieve the planned functional objectives.

After graduating in civil engineering with a specialisation in structures in 2019, I started working as a research technologist at the Astronomical Observatory of Cagliari, in the field of metrology.
In particular, my work is focused on the study of the environmental loads effects, such as gravitational load, thermal loads and wind action, on the Sardinia Radio Telescope, both using a modelling approach based on the finite element method (FEM) and using advanced metrological tools.
