This article presents the CubeSat Space Protocol ZARM Extension (CSP ZE), a novel approach to streamline satellite component integration and testing, addressing the growing demand for plug-and-play solutions in the rapidly evolving space sector. CSP ZE builds upon the lightweight CubeSat Space Protocol (CSP), introducing automated address allocation and dynamic user interface generation based on component capabilities. This facilitates efficient testing campaigns, particularly within the ZARM Bremen Drop Tower testbed, a key component of the Open6GHub initiative, designed for 3D network testing and satellite-in-the-loop experiments. The proposed system leverages the open-source OpenC3 Cosmos Project, enhancing it with a dynamic user interface driven by a capability description language, inspired by C header styles. The address allocation, managed through a simple incremental algorithm, ensures efficient utilization of the CSP address space. This research demonstrates the feasibility of a plug-and-play connectivity solution, ranging from satellite assembly to ground control software configuration, by extending open-source projects. By drawing inspiration from IoT concepts, CSP ZE aims to simplify access to the space domain, enabling faster development cycles and broader collaboration. This work focuses on the discovery concept of CSP ZE, detailing the design and mechanisms for automated address allocation and capability exchange, and highlighting its potential to facilitate rapid prototyping and deployment, especially in time-critical satellite service replacements.
