N2 - The rapid development of spacecrafts has led to the necessity of using high-performance computer systems on-board space missions. This requires a higher level of command and data handling specifications to satisfy those needs. As they regulate and synchronize different activities of a satellite or spacecraft, command and data handling systems (CDHS) are crucial parts of space missions. The CDHS' modular architecture provides flexibility, which is significant when developing satellite systems. This paper's objective is to introduce a hardware architecture for a modular, multi-layered command and data handling system. The on-board computer (OBC), which will launch on AlAinSat-1 and is based on the PC-104 platform, is the central component of the proposed CDHS architecture. In this paper, we also discuss the fully developed architecture which uses the cPCI Serial Space standard and other standard interfaces, such as PCIe. Next, we describe the benefits of flying the PC/104 computing layer of the CDHS architecture within AlAinSat-1. Finally, we present the results of the functional test and thermal vacuum testing that were done on the PC/104 computing layer of the CDHS architecture. In the future, we aim to complete the full testing of the four layers including the cPCI standard layer.
