Paper Abstract
The CHEOPS space mission will measure photometric transits of exo-planets with a precision of 20 ppm in 6 hours of
integration time on a 9th magnitude star. This corresponds to a signal-to-noise ratio of 5 for a transit of an Earth-sized
planet orbiting a solar-sized star. Achieving the precision goal requires precise on-ground calibration of the payload to
remove its signature from the raw data while in flight.
A sophisticated calibration system will inject a stimulus beam in the payload and measure its response to the variation of
electrical and environmental parameters. These variations will be compiled in a correction model. At the very end of the
testing phase, the CHEOPS photometric performance will be assessed on an artificial star, applying the correction model
This paper addresses some original details of the CHEOPS calibration bench and its performance as measured in the lab.
