Abstract
GREAT - a heterodyne instrument for high-resolution spectroscopy aboard SOFIA is developed by a consortium of German research institutes. The first-light configuration will allow parallel observations in two far-infrared frequency bands. We will have a choice of back-ends, including a broad-band acousto-optical array and a high-resolution chirp transform spectrometer. We describe the structural and quasi-optical design of the receiver, update on the front-end and back-end developments and discuss the data acquisition system.
