Nowadays, software development innovations are heavily found in electronic control units for the automotive sector. Software in this sector has grown considerably, though, the number of vehicle recalls because of software defects has grown accordingly. Because of this situation, different proposals arise in the various phases of the software development life cycle which aim to prevent these defects. In this article, we focus on the automotive requirements section and present, based on ISO standard 26262 and the SysML modeling language, a guide to effective requirement writing, specification and modeling.

We present a project to encourage students to venture into aerospace engineering projects, mainly in the emulation of communicating with the satellite and the earth station. In this exercise was proposed to use all the features of SATEX-II so they could understand a specific project and thus understand all the elements of the TV and play on to scale their communication with the ground station, with the ultimate to generate a comprehensive understanding. And we present to the conceptual design of the various elements of hardware that will Satex-II Satellite and in the most important aspects to consider in choosing the computer. Space conditions are totally different from terrestrial conditions, so the elements of the satellite's computer should be space technology, which require specific materials and fully redundant architecture for the proper functioning of the satellite, which depends mainly on the assigned mission.
