Abstract

A new trend in space systems is to move from big centralized satellites to smaller, but distributed systems: we call that formation flying, because the idea is to let several satellites achieve complex missions by combining the capabilities of payloads when they are distributed over several physical spacecrafts. For example, the Proba 3 mission will make use of two satellites to study the sun corona. The challenge is big, and will address all the questions that are raised when designing a distributed system: how to take decisions, how to detect faults, how to elect a master without any node knowing for sure the state of the complete system. To be ready to solve these issues, a rock-solid software development process must exist and be supported by tools, so that the system designer can concentrate on what is really new and challenging: the distributed algorithms. This chapter explains how the space sector in Europe tackled this problem of defining a proper development process, and what tools have been developed to deal with the specificities of embedded, heterogeneous systems. We first present the main characteristics of satellites systems and software, then the issues that are faced when developing them, what can be improved, and the concrete solutions that we developed in the scope of the TASTE project to ease the development, integration and validation of on-board software.
