  The Colorado Ultraviolet Transit Experiment (CUTE) is a 6U NASA CubeSat
carrying on-board a low-resolution, near-ultraviolet (2479-3306 A)
spectrograph. It has a Cassegrain telescope with a rectangular primary to
maximize the collecting area, given the shape of the satellite bus, and an
aberration correcting grating to improve the image quality, and thus spectral
resolution. CUTE, launched on the 27th of September 2021 to a Low Earth Orbit,
is designed to monitor transiting extra-solar planets orbiting bright, nearby
stars to improve our understanding of planet atmospheric escape and star-planet
interaction processes. We present here the CUTE autONomous daTa ReductiOn
pipeLine (CONTROL), developed for reducing CUTE data. The pipeline has been
structured with a modular approach, which also considers scalability and
adaptability to other missions carrying on-board a long-slit spectrograph. The
CUTE data simulator has been used to generate synthetic observations used for
developing and testing the pipeline functionalities. The pipeline has been
tested and updated employing ight data obtained during commissioning and
initial science operations of the mission.
