Orbits with Attitude

Been a while, I know. November was brutal. Somehow I have more work despite fewer credits. Built some CubeSat reaction wheels though, which was pretty cool. Also managed to fix up the simulation software a bit more. I added real orbital dynamics this time around. Previously I had been propagating the time from the simulation…

Show You the World

One of the cooler things I learned in the first half of this term is how to plot an orbit in 3D over a sphere representing the Earth. I also salvaged some old code from a friend that would project a map of the Earth over the sphere, so we can see exactly where over…

Wheel Plots

I’m more hesitant to boldly declare this set of plots a success, but I do think I’m on to something decent here. I’ve modeled the spacecraft with the same inertia properties and initial orientation and velocities that I’ve used before (found in this post). I’ve also given all the reaction wheels the same moment of inertia, 1×10-3…

Reaction Wheels Rolling

Reaction wheel functionality is slowly coming along in the attitude dynamics simulator. There’s some interesting changes with wheels that I had forgotten about since torque rods were the focus of pretty much all of my spacecraft simulation work. I’ve done some wheel based control simulations for high altitude balloons, but the scope of that was quite…
