The Next Generation Gravity Mission (NGGM) aims to enable high-resolution and high-accuracy measurements of the Earth’s gravitational field. Central to this mission is the operation of a high-sensitivity accelerometer within a thermally stable environment. Initial assessments have indicated that standard thermal control approaches are inadequate, prompting the need for a refined, high-performance thermal regulation framework. This thesis investigates the formulation and implementation of such an optimised thermal control strategy.
La missione NGGM ha l’obiettivo di misurare le armoniche gravitazionali terrestri con grande accuratezza e risoluzione. Per adempiere a tale scopo, è necessario utilizzare un accelerometro con prestazioni spinte in ambiente estremamente stabile, anche termicamente. Analisi preliminari hanno escluso la possibilità di affidarsi a misure di controllo termico convenzionali; è quindi richiesto un controllo più avanzato e ottimizzato che verrà approfondito in questa tesi.

Abstract
The Next Generation Gravity Mission (NGGM) aims to enable high-resolution and high-accuracy measurements of the Earth’s gravitational field. Central to this mission is the operation of a high-sensitivity accelerometer within a thermally stable environment. Initial assessments have indicated that standard thermal control approaches are inadequate, prompting the need for a refined, high-performance thermal regulation framework. This thesis investigates the formulation and implementation of such an optimised thermal control strategy.File | Dimensione | Formato | |
