The INFANTE project is a public-private initiative arising from the experience of Portuguese companies and R&D institutes in developing critical subsystems for space missions over the last 20 years. Using such building blocks, TEKEVER leads a consortium of 20+ entities currently developing a technology demonstrator microsatellite for Earth Observation. This paper addresses a set of technical challenges faced in the conceptualization of a satellite-borne SAR, along with new project-level approaches within the framework of new space while managing a large consortium of partners.
