Very understandable and instructive from the surface till the detailed parts
good
This course is a big opportunity to clarify a bunch of doubts about satellite communications, I really love the aerospace field, and this brief and objective information in the course has been son helpful.
I would like you to know that I truly loved the "Testimonies from professionals" sections, most of them were so inspiring to me, and motivated me to keep growing up in this matter.
I highly recommend this course!
AB
Nice introductory course, but too much material is pushed in format text into the "Going further" sections and the educational programs need the installation of LabVIEW and a toolkit only available on Windows.
