Sample Demos |
|
| Attitude3D | Simple sim using a CAD model of the spacecraft to view the attitude. Demonstrates control design using PIDMIMO, the Disturbances function, rigid body attitude dynamics with FRB, orbit dynamics with FOrbCart, and integration using RK4. The CAD model is viewed using DrawSCPlugIn. |
| Image Processing | Demonstrates image processing functions to showcase the edge detection abilities. It utilizes a canny enhancer to thin the edges to an almost prefect circle therefore increasing the precision of optical navigation. |
| Pressure Kalman Filter | Demonstrates a fuel mass Kalman filter for a blowdown system. The pressure measurement has 12 bits resolution and random noise. |
| Spacecraft Pointing | Demonstrates a spacecraft in orbit pointing at a target on the Earth. Uses a control system to quickly navigate to target and then rapidly approach steady state. |
| Shuttle Simulation | Simulate the space shuttle model. Demonstrates the ability to visualize a mission operation. The mission in this simulation is to simply open the shuttle main doors and extend an arm. |
| Telemetry | Demonstrates the application of the telemetry GUI. Streams data and displays it in real-time. Can also plot this data. Sample telemetry data is provided and runs for 1000 steps. |
| Three Axis Control |
Implements and simulates a spacecraft with reaction wheels and thrusters.
