How does a solar array drive mechanism work?
The first solar array drive mechanism engineering model developed by SSTL - the SADM-Twist - is based on the APM’s azimuth axis (illustrated in Figure 3), and mainly consists of a stepper motor with an integrated planetary gear box driving a spur gear transmission assembly to rotate the central shaft, which is supported by a duplex bearing.
What is a solar array drive assembly (Sada)?
Solar Array Drive Assemblies (SADA) are primarily used to rotate and position solar panels on satellites. The systems consist of a Solar Array Drive Mechanism (SADM) and electronics which are commercially available as standalone components or as a complete SADA solution.
What is a solar array drive assembly?
Solar Array Drive Assemblies, or SADAs, are an integration of mechanical and electrical components used for rotating the solar panels on the satellite.
What is a side-drive solar array drive mechanism?
The Side-Drive Solar Array Drive Mechanism (SADM) consists of a slip ring assembly and an actuator coupled by a spur gear set, which, when driven by suitable drive electronics, will position the Solar Array toward the sun for maximum power and transfer the collected energy to the spacecraft power bus.

What is a bi-axial solar array drive mechanism?
The Bi-Axial Solar Array Drive Mechanism includes two rotation axis assemblies as illustrated in Figure 4: The lower axis assembly consists of a traditional SADM and is responsible for continual tracking of the sun.
What is karma-5 solar array drive mechanism (SADM)?
The Kongsberg KARMA-5 is a third generation (TG) Solar Array Drive Mechanism (SADM) designed for space applications. It can be configured with one, two, three, or four slip ring modules depending on power requirements. KARMA-5 TG SADM also consists of a PCB-based Slip Ring providing a compact design and enabling a wide power range.
