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° 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.
Key Features:
- LEO, MEO and GEO orbit capable
- Low noise twist capsule design
- High stiffness of output
- Compact design
- Moog compatible drive electronics available
