Latest Patents

One of Nakano's key patents is titled "Sun-referenced safe-hold control for momentum biased satellites." This patent describes a sun-referenced safe-hold control system that utilizes a safe-hold processor responsive to a set of sun sensors. These sensors detect attitude errors of the solar wings, allowing the safe-hold processor to provide independent control logic. This logic rotates the solar wings to ensure that sunlight is consistently incident on them, thereby maintaining solar power in the safe-hold mode. Additionally, the safe-hold processor controls the momentum wheel to place the spacecraft body in a passively stable nutational state. This innovation increases the period in which spacecraft health is guaranteed by adding active, closed-loop control of the solar wings.
