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. +/- 184掳 rotation of the solar array is facilitated by the integrated motor and twist capsule. Output position telemetry is made available using a potentiometer. The drive axis is comprised of a 2 phase stepper motor and a gear transmission accommodating an open-loop command and control scheme.
