Pointing mechanism
WebJul 28, 2024 · The hybrid mechanism developed in Xiu et al. uses a two-axis gimbal and two single-axis FSMs, where the FSMs achieve image motion compensation and the gimbals complete the pointing control. Ground imaging and flight tests are made to verify this method and ensure an accurate LoS between terminals.
