Standardization concepts for CubeSat applications

Due to physical/power/financial constraints of CubeSats, classical improvements of reliability in area of satellite avionics and data-handling (i.e. redundant subsystems, cross-strapping) are not usually possible. On top of that, CubeSat development rarely follows technical standards, and is usually based on COTS solutions additionally questioning reliability figures.This article proposes the use of concepts implemented usually on "bigger" satellites migrated into the world of CubeSat applications. Those concepts are described in SAVOIR working group, which standardises certain data-handling functionalities expected to be present in "mature" satellite. By applying specific engineering solutions and guidelines, most of the SAVOIR functions can be implemented in CubeSat, therefore increasing the reliability.
