Satellite Communication Technology
Understanding the parameters of satellite systems from sending the satellite into the orbit and the link budget to the communication application.
- repeat the basic characteristic of satellite communications
- explain division of satellite communication systems according to the application
- compute satellite link budget
- analyze the architecture of satellite communication systems
- design specific satellyte communication systems
- evaluate the quality of satellite communication system
Forms of Teaching
Lectures are given with the use of powerpoint presentations published on the web pages. The lectures are organized through 2 cycles. The first cycle consists of 7 weeks of lectures and midterm, while other cycle has six weeks of lectures and final exam. The lectures are given in total of 15 weeks, two hours per week.Exams
One midterm exam.Laboratory Work
Consultation term is determined on the first lecture in agreement with the students.
|Type||Threshold||Percent of Grade||Threshold||Percent of Grade|
|Attendance||0 %||10 %||0 %||0 %|
|Mid Term Exam: Written||0 %||40 %||0 %|
|Final Exam: Written||0 %||40 %|
|Final Exam: Oral||10 %|
|Exam: Written||0 %||90 %|
|Exam: Oral||10 %|
Students who have earned enough points to pass the exam do not have to take oral exam (they will get 0 points in that case).
