CubeSpec: development of the Payload Control Unit for a high-resolution spectroscopy CubeSat

Abstract
The CubeSpec mission at KU Leuven brings optical spectroscopy to a 12U CubeSat platform to study massive stars, addressing the challenge of integrating advanced instrumentation in a compact, power-limited spacecraft. High pointing stability is achieved through three piezo actuators rotating a Fine Steering Mirror in closed-loop feedback with a Fine Guidance Sensor and actuator strain-gauge readings. The guidance and science detectors use GSENSE2020BSI CMOS sensors, each interfaced by an Artix-7 FPGA and streamed to a Zynq-7000–based payload processor. Additional components include high-voltage piezo drivers, an ADXL355 microvibration experiment, and CSP-based links for onboard communication and science data transfer.
