Avionics for satellites is a market which is continuously growing in these years, especially thanks to the availability of low cost launch vectors. This cost reduction enabled many institutions (industries but also universities) to develop their own satellites. A first result of this process was the CubeSat concept: a really small satellite, built using low(More)
This paper presents the architecture of a small university satellite that we have developed. The main design criteria were low cost and fault tolerance, which have been achieved by using commercial off the shelf components and by replicating all critical functions, while monitoring the state of the system for failures. The focus of the paper is on overall(More)
PicPot is a small satellite designed and built at Politecnico di Torino, as a cooperation between the Electronics and the Aerospace Departments. The goal of the project is mainly didactic: a real satellite is a good example of complex system, with specific constraints and requirements. Such a project makes possible to have students, in the final graduation(More)
Many universities are now involved in projects related to design, assembly, and operation of small satellites. These projects, with participation of researchers and students, and support of external companies, do not aim to compete with commercial satellites; the main goal is to increase the experience level which contributes to make space applications(More)
The cost-effective access to space envisaged by ESA would open a wide range of new opportunities and markets, but is still many years ahead. There is still a lack of devices, circuits, systems which make possible to develop satellites, ground stations and related services at costs compatible with the budget of academic institutions and small and medium(More)
COTS components are gathering more and more interest from satellite developers thanks to their lower cost and ease of procurement as compared to space qualified ones. A number of studies to evaluate the possibility of COTS use in space systems are under way: automotive and consumer electronic devices are evolving fast and their innovative solutions can have(More)
