Oral Examination held on 24/02/2026. My aim was to take something which is easy and complete the ECTS. This was my last exam for M.Sc AE.
Prepared for 3 days with the help of a condensed note from my friend Yash T and the protokolls. Saw some YouTube Videos. No prior knowledge of the subject. Scored a 1.0
I am also uploading the condensed note for future reference.

6-During this position determination, what is measured. Give the basic formula.
7-What are the type of disturbances encountered while the signal transmission in the atmosphere?

15-Why does clock errors occur? Causes. - Relativity
16-What are the problems when the receivers are placed on satellites?
17-You want to launch satellites and want to get coordinates of south pole of moon. Where do you want to position the satellites? And why. ( i was not sure but then Professor told at Apogee. Then he asked why? i told its speed is slowest. i added that DOP is bad. He told that is a good point and gave extra points for that.)
Tip:If you like 1-0-1 oral. Go for it. Group Assignment/ Group Oral Exam is something I hate here.
