Intro to Frameworks

To avoid writing the flight-software from scratch for new missions, some organizations have developed so called Flight-Software Frameworks (FSWF), with the intention of decreasing the time and resources needed to implement the flight software, but also for ensuring basic functionalities, standards and safety measures, along multiple missions.

All FSWF aim to be reusable software architecture that provides the core building blocks needed to develop, integrate, and operate software for spacecrafts. They provide common generic services that can be tailored for specific missions.
