Software development for space applications is characterized by historically grown structures and conservative methods derived from traditional project management. Many of these methods are not easily transferable from normal product development to software development. Project risk is high and delays are the rule due to the many uncertainties regarding the planned cost and time budget, possible requirement changes in later project phases as well as unforeseeable complications. Furthermore, these methods have very limited flexibility and come with highly time-consuming planning, implementation and, if necessary, problem solving. Agile software development does not require that all requirements are known and well-defined at the beginning of the project. The development is incremental and generates a usable and testable software product with every new iteration. This makes the development more flexible and problems can be detected earlier and solved with less effort. Due to the frequent integration into the existing system, a close collaboration is possible across subsystems as well as the customer or the project partners. This increased flexibility and improved cooperation reduces project risk, cost and time until delivery. This paper shows the application of agile software development in the space sector applied to a CubeSat project. Within the student satellite project Munich Orbital Verification Experiment II (MOVE-II) at the Technical University of Munich (TUM) the concept of agile software development was successfully applied to develop the software of the on-board computer within a few months. The agile methods presented in this article demonstrate software development that does not require the final requirements at the beginning of the development process. These methods allow that a new version of the software can be tested and operated after every iteration of the process. The launch of our CubeSat MOVE-II is scheduled for early 2018.
