The teaching style was very good, it was easy to follow the class even for non-native English speakers.

Learning the terms and how they play a role in GPS and how equipment processes GPS signals [was useful to my work]. The 2-day course discussed many of the terms I deal with in my job.

“The instructor gave enough technical details without losing the non-technical audience. I also found the instructor’s wit and humor very effective. Well done!”
