This course has been conceived to teach the students how to design a small satellite or Cubesat mission for Earth Observation. Students will learn which are the subsystems of these small satellites, their main characteristics and design constraints, and will practice how to design and plan a mission. Students will also learn about the recent and current history of Cubesat missions, the Earth observation sensors that can be boarded on these satellites and their limitations, and they will be able to understand how to use the data from these missions.
Prerequisiti
Basic knowledge about physics (electromagnetic waves), remote sensing sensors (passive and active sensors) and data (digital numbers, processing levels).
Metodi didattici
Lectures and practical sessions using open access software.
Verifica Apprendimento
The students will be asked to discuss a case study and provide a report that will be evaluated.
Testi
The slides used by the teacher will be provided, together with a list of relevant books and literature papers.
