Spacecraft Controllers
Gimbal Control Electronics (GCE)
The high-reliability Gimbal Control Electronics System controls the motion of two or more motors, such as used in solar array actuators and antenna gimbals.
Rikishi Electronics Unit (REU)
The Rikishi Electronics Unit (REU) is a Robotic Arm Controller designed to drive up to nine separate servo motors (joints), such as found on robotic arms or articulated structures. The REU provides a platform for command and telemetry processing, execution of motor control commands and algorithms, execution of general purpose commands, and storage for volatile and non-volatile data.
Missions: DARPA/MDA SUMO and Phoenix Programs
Electronic Control Unit (ECU)
The Moog 2-channel Electronic Control Unit (ECU) is comprised of 2 hybrid stepper motor controllers, an EMI filter, and 6 analog pass-throughs for telemetry. The ECU enclosure has been designed to allow 2 ECU’s to be stacked to form a 4-channel ECU. The ECU contains all power conditioning, pulse sequencing and output driver stages necessary to drive two 3-phase motors. The system electrical interface consists of power and command input lines, output motor drive lines and telemetry outputs.
Missions: ORBVIEW, ROCSAT, KOMPSAT
Reconfigurable Actuation Control Unit Family
Part of the Reconfigurable Actuation Control Unit (RACU) family, these controllers deliver a wide range of performance capabilities with customizable design parameters. Built on Moog’s proven heritage, this product line emphasizes cost efficiency, faster lead times, and modular, reconfigurable designs—ideal for rapid development and evolving solutions.
