The version I use is `MATLAB_R2023b`. - Run [adcs_20231001_beforerun.mat](adcs_20231001_beforerun.mat) first, this creates an Earth-centered spatial grid for visualization. - Then, run the Simulink file [adcs_visual_20230921.slx](adcs_visual_20230921.slx). - To visualize the CubeSat orbiting, click the `visualizeSatellite` block at the very right side, and then hit the `Run` button. This will give you the orbiting simulation. - To stop the animation, hit the `Stop` button.
