Steve Ulrich is the Director of the Spacecraft Robotics and Control Laboratory in the Department of Mechanical and Aerospace Engineering at Carleton University. He received his B.Eng. (2004) and M.A.Sc. (2006) in electrical engineering from the Université de Sherbrooke, and his Ph.D. in aerospace engineering (2012) from Carleton University. From 2006 to 2008, he was Spacecraft GN&C Research Engineer with NGC Aerospace Ltd, where he namely led the development of an innovative attitude perturbation estimation system for the European Space Agency’s PROBA-2 spacecraft. In 2013, he was Postdoctoral Associate with the Space Systems Laboratory at the Massachusetts Institute of Technology, where he contributed to the development and experimental validation of vision-based relative navigation and control aboard the International Space Station during expeditions 34 and 35.

where is Introduction to Spacecraft GN&C - Part 2 ? please guide me

[@talentbuilderbuddy3746]

It helped me a lot in understanding the behavior of satellite ... Thank you so much for key knowledge

[@gossipGirlMegan]

The best GNC lecture I've heard.

[@BlackHermit]

Great lecture, thank you so much for uploading this!

[@antonellamuto8256]

Much interesting! I’ve learned a lot about GNC functions in spacecraft model

[@celilylmaz4426]

Great lecture for GNC enthusiastics, thank you sir.

[@aerohk]

Very interesting, thank you for your work. I used to help make satellite flight control computer, but not educated in the flight software. Appreciate the lecture

[@Wonderhow96]

Great lecture to start with the GNC topic outside a University!

[@MemoryofMichaelJackson]

Good information .....I look forward for your new videos

[@AnilKumar-ch5mw]

Awesome lecture sir, thanks a lot

[@abhishekrajan4073]

Very nicely explained sir, thanks a lot,

[@pelayo8465]

Thank you for the help

[@dbr_199]

What major would be prefered to work as a GNC engineer? CS, ElecEng, MechEng?

📺💬 ODC, sensors, feedback, and controls. There are a lot more when talking about the controls system to help the satellites travel along the orbit in the shade of the sun.
🥺💬 There are multiple pages I see from the materials where sensor and controls it is digital sensors and analog sensors signal control. Navigation included estimates of targets or values and how does it different than digital signals⁉ 🧸💬 It does not require quantization and some values from different scales can compare with the same domain.
( They added conversation 📺💬 Do you understand they will not stop and try to do IQ test can you remember they keep the speaker and those flies running 🥺💬 I did not pay attention to them but I read from your share of knowledge🔊🗯 กรุณายอมนะไอ้แม่ ... 🏡🥺💬 เกี่ยวอะไร ไม่สนใจ )

Please help me in solving this problem:
The initial (3-2-1) Euler angles yaw, pitch and roll of a vehicle are (\psi, \theta, \phi)(ψ,θ,ϕ) = (40, 30, 80) degrees. Assume the body angular velocity vector of the craft is given through the BB frame components as Bωω=⎡⎣sin(0.1t)0.01cos(0.1t)⎤⎦20deg/s. Write a program to numerically integrate the yaw, pitch and roll angles over a simulation time of 1 minute. Enter the Euler angle norm \sqrt{\psi^2 + \theta^2 + \phi^2}
ψ
2
+θ
2
+ϕ
2
at the simulation time step 42s. Express angles in radians.
[Hint: if you are unsure, look at the "Optional Review: Integrating Differential Kinematic Equations" video.]
[​Hint: In the integration, start with the initial angles and just integrate them without mapping them to specific quadrants
