Satellite Reference Frames, Viewing Geometry, and Mission Analysis

Incredible work doctor , the accompanying documentation youve put into your videos and referencing them all together into a cohesive course is invaluable. Much appreciation from a fellow aerospace engineer who needs a refresher on attitude dynamics once in a while. Do you happen to have a book published that might accompany this course and serve as a reference manual?

I litterly listen to this lecture while working out. Really cool sauce

[@ProfessorRoss]

This is amazing! I had no idea my lectures were something one could work out to. I should really explore that angle further. 🤔👍🏼

he is just perfect.

Sir thanks a lot. this is amazing

[@ProfessorRoss]

So nice of you

Hi, I have a question about why only the circular orbit makes o1 the direction of velocity? From the formula, isn't it general? h = r x v, -o2 = -o3 x o1 so that o1 = v

[@ProfessorRoss]

While h is perpendicular to both the r and v vectors, for an elliptic orbit, the r and v vectors are generally NOT perpendicular to each other. Only in a circular orbit is this always the case. You can convince yourself by looking at an elliptical orbit diagram like the one here web.njit.edu/~gary/320/Lecture6.html
