Design of a Highly Integrated and Intelligent Data Processing and Transmission Distribution System for Microsatellites

With the widespread application of microsatellites in fields such as remote sensing, communication, and scientific exploration, traditional satellite data processing and transmission architectures face challenges such as low functional density and insufficient intelligence. This paper proposes a highly integrated and intelligent data processing and transmission distribution system design. Tailored to the characteristics of microsatellites, such as light weight, small size, and high functional density, an integrated design of the data transmission processing and transmission system, as well as the information distribution system, has been developed. This design achieves high integration of multiple functional modules including power distribution, control, processing, storage, modulation, demodulation, distribution, and power amplification. Featuring technologies such as software-defined data processing, software-defined radio, an open and easily expandable architecture, autonomous mission planning for multiple types of tasks, and intelligent collaboration, the system significantly enhances the functional density ratio and intelligence level.
