The chapter is dedicated to briefly present all the major sensor typologies for spacecraft guidance, navigation, and control (GNC) applications, to discuss their operating principles, to highlight their peculiarities, to categorize the available components according to their performances, and to discuss the most relevant modeling techniques and rules. The sensor modeling techniques are presented, discussing the main implementation principles of the most common numerical models to include the sensor behavior in the GNC design, analysis, verification, and validation phases. The main error sources and their modeling are introduced, together with the most typical sensor faults. Moreover, this section contains some elements of metrology, and it explains some basic principles of statistics and random variables representation. Orbit and attitude sensors are presented, comparing the available performance and discussing the main characteristics. Specific sections on inertial sensors, electro-optical sensors, and altimeters are also included.

Abstract
The chapter is dedicated to briefly present all the major sensor typologies for spacecraft guidance, navigation, and control (GNC) applications, to discuss their operating principles, to highlight their peculiarities, to categorize the available components according to their performances, and to discuss the most relevant modeling techniques and rules. The sensor modeling techniques are presented, discussing the main implementation principles of the most common numerical models to include the sensor behavior in the GNC design, analysis, verification, and validation phases. The main error sources and their modeling are introduced, together with the most typical sensor faults. Moreover, this section contains some elements of metrology, and it explains some basic principles of statistics and random variables representation. Orbit and attitude sensors are presented, comparing the available performance and discussing the main characteristics. Specific sections on inertial sensors, electro-optical sensors, and altimeters are also included.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
