Mapping it out

Charting a course After moving cross country and starting a new job, I’ve finally settled down enough to make some more progress on my python simulations (thanks to having a long weekend without traveling). I’m moving on to setting up a Python lander simulation with some Martian terrain. I’d like to mess around with some…

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…

Preliminary Plots 2

First cut, second post. Last time I mostly talked about the background and inner workings of the attitude dynamics simulation I’ve upgraded. Now I’ll talk a bit more about the advanced stuff that’s included. I mentioned the mechanisms that allow our little CubeSat to orient itself to where we want, and promised to talk about how…

Preliminary Plots

Success! For now… The first cut of my attitude dynamics simulator upgrade appears to work. There wasn’t too much substantive change in terms of the control theory in this upgrade – I mostly re-organized the configuration scripts and made them more modular for easy editing and modelling of different spacecraft. I also added a progress…
