Frontgrade unveils SADA-10 drive to increase efficiency for LEO and MEO satellites

Frontgrade Technologies has introduced the SADA-10, a compact Solar Array Drive Assembly designed to support precise solar array positioning for Low Earth Orbit and Medium Earth Orbit space missions. Built using knowledge acquired from previous flight systems, the SADA-10 features a hybrid stepper motor paired with a harmonic gear drive, delivering high torque, zero backlash, and 0.015-degree positioning accuracy to enhance solar tracking and power output in orbit.

The unit incorporates dual potentiometers for redundant position sensing. Its power-efficient circuit design limits power draw, facilitating efficient power and data transfer while minimizing spacecraft complexity and improving overall power bud
