Abstract

The COronal Diagnostic Experiment mission requires precision attitude pointing and stability in the arcsecond range to study coronal mass ejections from the Sun. While the Wallops Arc Second Pointer platform successfully flew the predecessor mission and provided sub-arcsecond pointing from a high altitude balloon, the transition to spaceflight aboard the ISS introduces many new challenges. This study proposes the introduction of both a modified state observer and a neural network controller to address these challenges, replacing the traditional PID controller used in the past. Results show that pointing precision and stability can be improved using the new methodology.
