Research on Integrated Interface Design of Small Modular Spacecraf

Modularity in space provides a solution to the scale-constrained problem of space systems, while providing other benefits in terms of flexibility, sustainability and affordability. In the system, modules are added and removed through interconnect interfaces, which transfer mechanical load, data, electrical power, and heat from one module to another. The current research tends to integrate multiple functions into a single device or equipment to reduce costs and improve standardization. This article will explore the design requirements and constraints that need to be satisfied in the design of this standardized, extensible, multifunctional (mechanical, electrical, data, thermal), modular interface, and compare the realization of each function to provide a design consideration.
