The ANDES-project entered phase B in January 2022. Among its main scientific goals are the detection of atmospheres of exoplanets and the determination of fundamental physical constants. For this, high radial velocity precision and accuracy are required. Even though the ANDES-spectrograph is designed for maximum intrinsic stability, calibration is mandatory. This talk provides and update of the current baseline design of the spectrograph with special emphasis on the calibration unit(s).
