Onboard wavelength calibration of the CubeSpec high-resolution spectrograph using a Fiber Fabry–Pérot Etalon
CubeSpec is a 12U CubeSat mission designed to demonstrate high resolution spectroscopy from a compact platform, with launch readiness targeted for early 2027. Its cross dispersed echelle spectrograph requires an onboard calibration system that is very compact, mechanically robust, and sufficiently stable and precise to...
