SMALL SATELLITE SOLAR ARRAY DRIVE ASSEMBLY (SADA)

The small satellite Solar Array Drive Assembly (SADA) is a lightweight and compact power solution for positioning solar array panels. Continuous rotation of the solar array is facilitated by the integration of a slip ring assembly. Position telemetry is made available using Moog’s noncontact position sensor technology. The SADA is comprised of modular components, allowing modifications to meet mission specific requirements. The drive axis is comprised of a stepper motor and a gear transmission accommodating an open-loop command and control scheme.
