The 4I4U project, which runs through 2022, aims to engage the community of citizens made up of students between the ages of 15 to 23 in the urban mobility of the future while empowering them to become actors of change who can participate in the development and evolution of their city. Led by a European Consortium composed of two cities, Barcelona in Spain and Toulouse in France, as well as education entities from high school to universities and clusters of companies in the field of urban mobility, and co-funded by the EIT Urban Mobility, the main objectives of 4I4U focus on raising awareness among young citizens in the context of urban mobility, developing their capabilities to become actors, highlighting their needs and finally creating a methodology and an environment that help students from ideation to action for the mobility of the future. The objectives of 4I4U are achieved by planning a set of seminars, round tables and brainstorming sessions to raise awareness or understanding of different aspects of urban mobility. To move from ideation to action, small groups of students design and produce a first ideation to understand and be able to project themselves into the proposed solution. This activity will be carried out under the mentoring of cities and industrialists, using the means of training institutions.

Despite their limited lifespan and reduced cost, nanosatellite missions have proved to be suitable platforms for Earth observation, scientific experiments, and technology demonstration. During the last years, the number of nanosatellite missions has noticeably increased, posing the need to improve several system characteristics to ultimately endorse the full potential of this class of spacecraft. In this context, this paper presents three design guidelines that can be applied in nanosatellite software to improve the system robustness, modularity, and autonomy. The design guidelines presented in this paper, namely, hierarchy-enabled robustness, payload-oriented modularity, and onboard planning capabilities, are complemented with a structured review of software techniques and architectural concepts that have been found in the literature. The paper justifies that these systemwide qualities are some of the most critical when designing flight software for CubeSat-like spacecraft and explores how they can improve mission performances and operability, enhance the system’s tolerance to failures, and ease the development cycles. Finally, this paper illustrates the application of the design guidelines by detailing the onboard software architecture for the Cat3-1, a CubeSat program carried out at the Nano-Satellite and Payload Laboratory of the Technical University of Catalonia—UPC BarcelonaTech.
