The aim of this study is to evaluate the application of the domestic radiation-hardened system-on-chip (SoC) 5510TC028 in creating onboard data acquisition systems of Earth remote sensing (ERS) spacecraft. The key advantage of this SoC is the integration on a single chip of a 32-bit RISC-V processor core and a Field-Programmable Gate Array (FPGA) interconnected via an internal high-speed bus. The work methodology involved testing on a development board. A test configuration was developed to verify the correct interaction between the processor and the FPGA via standard interfaces, and to evaluate the operational frequency and data exchange performance. The experiments confirmed the system’s stable operation. A data transfer rate between the cores sufficient for the target tasks was achieved and the maximum operating frequency was determined. On the basis of an analysis of modern ERS spacecraft requirements and development trends, the article shows that the integration of components, confirmed radiation tolerance, compactness, and use of the domestic component base make the SoC 5510TC028 a ready and promising solution for developing onboard equipment for future Russian space missions.
