Development of onboard software for KvarkenSat

Abstract: This Master thesis work presents the design, development and testing of theonboard software for the KvarkenSat CubeSat project by the Kvarken SpaceCenter. Traditionally software design in the space sector is done with a designdriven method. This project instead aims to use an agile approach where workis done incrementally, and the design evolves over the course of the project.The resulting work of this project is a mostly implemented and tested software.For future work with agile development use of hardware in the loop testing ofsimulated payload or subsystems to avoid reliance on early delivery of hardwareis recommended.
