Small Satellite Solar Array Drive Electronics (SADE)

Small Solar Array Drive Electronics

The small satellite Solar Array Drive Electronics (SADE) controller is compact solution for interfacing with our small satellite Solar Array Drive Assembly (SADA). The SADE consists of a serial RS-422 interface to receive commands and send telemetry to the spacecraft host. The SADE is a motor driver capable of controlling current and speed of the motor via commands provided by the spacecraft host. The SADE is comprised of space rated radiation tolerant components capable of operating in a LEO environment.
