Table 4 Summary of the challenges associated with the spin attitude stabilization and flexible structures and the steps taken to address them
Challenges | Solutions |
|---|---|
Spin instability in the initial configuration | Active nutation control using RCS |
Nutation angle (tilt angle) | Comprehensive management of the mass properties from the component level to the system level, including the design, testing, and adjustment |
Spin stability (momentum-of-inertia ratio) | |
Libration motion of the wire antenna | Moderate MTQ control and demagnetization |
Libration tests of a wire probe antenna on the ground | |
Determination of the spin axis | Newly developed spin-type star scanner |
