The professor is available to interact with students in English, also during the examinatio
The course aims to provide students with the theoretical and practical foundations of Satellite Navigation.
The course is aimed at developing the student's ability to acquire data with Satellite Positioning Systems, to process and to analyse them critically.
Knowledge and understanding: The student must demonstrate knowledge and understand the issues related to the acquisition, processing and representation of GNSS data, in order to solve problems in navigation, survey and representation.
Applying knowledge and understanding: The student, applying the theoretical and practical concepts acquired during the course, must show that he is able to use satellite navigation systems and, moreover, must be able to manage the satellite data on cartographic support.
Making judgments: The student must be able, autonomously, to evaluate the single problem and adopt the best solution methods, even in situations different from those presented by the teacher during the course.
Communication skills: The student must be able to explain, even to non-expert people, the concepts of Satellite Navigation in a simple way but with a suitable technical-scientific language.
Learning skills: The student must progressively acquire autonomy in the study of the topics covered by the course. Furthermore, he must be able to update himself by consulting texts and scientific publications in differ languages, as English.
Knowledge of the topics developed during the Mathematical Analysis, Physics, Geodesy and Navigation courses.

Modality of verification of learning:
The exam, aimed at verifying the achievement of the training objectives set, consists of an oral interview with theoretical/practical questions.
To this end it is emphasized that, during the interview, various technical supports will be used (cartography, monographs, software, etc.).
In order to pass the exam, the student must know:
- quickly frame the requested topic (min 6 – max 10);
-expose the program’s topics with appropriate technical vocabulary (min 6 – max 10);
-Apply the theoretical concepts to practical cases proposed by the teacher (min 6 – max 10).
Attendance is not compulsory but participation during the lessons greatly simplifies the study phase.
It is emphasized that, during the course, seveal exercises are carried out by actively involving the students.
