An advanced cryogenic ratchet wheel drive has been developed based on experience from the GIRL project. Power dissipation, microphony, lifetime and positioning accuracy have been significantly improved. Three of these wheels equipped with filters, apertures and mirrors compose the core of the photometer experiment for ISO.
