Rocket Guidance Navigation and Control

First video of my new series idea, a brief overview of Rockets Subsystems. This video covers what the Guidance Navigation and Control (GNC) subsystem does and how it operates.

If you want to build anything I'm developing or want part files become a patron! These will come in the form of share drive access. Supporting makes it possible for me to develop more stuff and fly more rockets!

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.
The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

Bro you're the only one on YouTube covering stuff like this. Keep it going! Ya got a subscriber in me :)

[maywah]

Proud of you young man, show it for your quality to the world, I really like you thank you so much for your video, May God bless you always.

[YukonK]

I liked this video! I like how you explain the basic logic of the control system

[NovatrimAnima]

Much joke in this video make it's not boring. I like content like this

[OrionAerospace]

Great video! The production quality stepped up a ton and the animations were great! Keep up with the good work!

P.S I recognize that background music from one of our videos ;P

[prudvi]

How the hell is this channel so underrated?? You have great content!

[kalpeshwani]

Your explanation too was slow & steady stabilized towards intended direction.

"You will have to find a happy medium between all of those" --- As a mechanical engineer, I perfectly feel this.

[nadavram]

Please make more videos like this! This was absolutely great!

👍 acronyms are fancy 😊
That’s half the fun with aviation
The other half is human performance and limitations

Then the rest of the day we can spend with the birds 🦅

Very interesting. I was part of the initial 1970’s Space Shuttle program on a team designing the APU’s for powering TVC and other functions. Our APU’s have been modified for use on the SLS. Old timer 😎😎

This was a really great video that I heavily enjoyed

[syedhammadhussain]

Mann you're damnn motivational. That calm music and rocket going boom in the background. I might also get lill off path and do MS in rocket science 😁

[andrewmatteson]

Did you ever do a follow up on 14:21? My AE senior design group are looking at doing an active aero mid power rocket.

[mikesmusicmeddlings]

Oh I see some Kerbal. Man they need to get the sequel finished!

[GryffieTube]

I love what you are doing so I just subscribed. Keep the videos coming please!

[kelvinfeliciano]

Perfect info for my upcoming interview.

[maximusnovikoff]

Great video! Definitely continue the format. Ceep it up!

[CoolThingsKidsShouldKnow]

Great video. I am glad Tory recommended it..
