Schemazeichnung eines geostationären Satelliten mit drehbaren Solarpanelen.
Ein Solar Array Drive Mechanism (SADM), zu deutsch Mechanismus zum Drehen von Solarmodulen, ist ein Gerät auf dreiachsig stabilisierten Satelliten, das die Solarzellen optimal zur Sonne ausrichtet. Bei einem geostationären Satelliten liegt die Achse der Solarpanele senkrecht zur Flugrichtung und parallel zur Erde.
Ein SADM ist technisch sehr anspruchsvoll, da hohe elektrische Leistungen von bis zu 25kW und Steuersignale über Schleifringe von den Solarpanelen zum Satelliten übertragen werden.
