This chapter explains the concept of perturbation, discussing the major external and internal perturbations sources. External perturbations are those properly related with the surrounding space environment, while internal perturbations are related with the elements inside the spacecraft, which anyway influences the satellite dynamics. The combination of the two composes the complete space environment. As a matter of fact, the internal perturbation sources are characterized by the fact the satellite is in space and not on ground. The main guidelines to model the external and internal perturbations and their influence on the guidance, navigation, and control chain are carefully explained in this chapter.

Abstract
This chapter explains the concept of perturbation, discussing the major external and internal perturbations sources. External perturbations are those properly related with the surrounding space environment, while internal perturbations are related with the elements inside the spacecraft, which anyway influences the satellite dynamics. The combination of the two composes the complete space environment. As a matter of fact, the internal perturbation sources are characterized by the fact the satellite is in space and not on ground. The main guidelines to model the external and internal perturbations and their influence on the guidance, navigation, and control chain are carefully explained in this chapter.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
