Development of an STM32 based on-board computer for small satellites & CubeSat missions

We present here an STM32 microcontroller based on-board computer designed for use in small satellites and CubeSat missions that was developed using commercial-off-the-shelf (COTS) electron- ics components. An on-board computer (OBC) is one of the important subsystems of any CubeSat mission. An on-board computer is the central brain of a CubeSat or small satellite, responsible for coordinating and controlling various subsystems to achieve mission objectives efficiently and autonomously. It performs cru- cial tasks like power management, communication, command and data handling, on-board data processing and on-board software execution. This paper discusses the development of one such OBC designed for a spectroscopic mission called Spectroscopic Investigator of Nebular Gas (SING).
