Sensore stellare per controllo assetto di piccoli satelliti.

Sensore stellare per controllo assetto di piccoli satelliti.

The project consists of an integrated system including a star tracker and a 3-axis rate gyro for controlling the attitude of small satellites (micro and nano). The project adopts an APS (Active Pixel Sensors) as an image sensor coordinated with an optical system, a 3-axis gyroscope for the measurement of angular velocity and the PIC32MZ as microcontroller. This control system, characterized by measurement accuracy to the tenth of a degree, usable in small satellites that for size and mission budget must generally do without, can add important information for the interpretation of the measures for which a satellite mission is intended.

Sara Scibelli, Vincenzo Ferrara, Fabrizio Frezza - Electronics for the Environment Lab. - Dept. DIET - Sapienza University of Rome,

Sara Scibelli: was born in Rome on 18/12/1994. She is an undergraduate student in Electronic Engineering at “La Sapienza” University of Rome. Her studies concerned Earth's Observation and, in particular, systems and design techniques for terrestrial and satellite communication.

Vincenzo Ferrara: Associate Professor of Electronics at the Department of Sapienza Sapienza University of Rome, is the scientific manager of the Laboratory of Electronics for the environment of the Diet where he conducts research on sensors and systems distributed throughout the territory.

Fabrizio Frezza was born in Rome, Italy, on October 31, 1960. He received the “Laurea” (degree) “cum laude” in Electronic Engineering in 1986 and the Doctorate degree in Applied Electromagnetics and Electrophysical Sciences in 1991, both from “La Sapienza” University of Rome.
In 1986, he joined the Department of Electronics of the same University, where he was Researcher from 1990 to 1998, temporary Professor of Electromagnetic Fields from 1994 to 1998, Associate Professor from 1998 to 2004, and he has been Full Professor of Electromagnetic Fields since 2005.
His research activity has concerned guiding structures, antennas and resonators for microwaves and millimeter waves, numerical methods, scattering, optical propagation, plasma heating, anisotropic media, artificial materials and metamaterials, cultural-heritage applications.
Dr. Frezza is a Member of Sigma Xi and Senior Member of IEEE and OSA.
