The design of a highly integrated and open architecture micro-satellite

Large-scale constellation applications will represent a significant trend for micro-satellites, with adapting to low-cost, mass-production development and intelligent space-ground integrated applications serving as key directions for micro-satellite technological advancement. This paper introduces a highly integrated and open architecture micro-satellite designed to enhance rapid design and flexible construction capabilities. By integrating computing and processing capabilities, a unified high-speed bus interface is employed to manage the aggregation of information flows, achieving a high degree of hardware-software integration. The architecture enables the open loading and invocation of application-oriented software through standardized interfaces, as well as the scalable configuration of components such as power systems, radio frequency modules, and control systems, thereby facilitating open expansion and development of satellite functions. The micro-satellite architecture proposed in this paper supports various payload applications, including remote sensing and scientific experiments, providing technical support for advancing large-scale constellation construction.
