Abstract

WindCube is a NASA HFORT funded mission to study the coupling of thermospheric winds with the earth’s ionosphere. The optical system is based on a limb sensing Fabry-Perot etalon designed to measure the Doppler shift of the 630 nm oxygen airglow emission. The instrument payload is designed to fit within a 6U volume in a 12U CubeSat. The accuracy requirement for the wind speed retrieval is 5 m/s. This is the driving requirement for the opto-mechanical stability of the etalon system. Active temperature control of the etalon is employed to keep the mounted etalon within a +/- 0.1 C range. This paper discusses the design and analysis of the mounted etalon system to meet the accuracy requirement as well as surviving the rigors of vibration testing and the launch environment.
