Abstract
Targeting the needs of low-earth orbit (LEO) Internet constellations for the high performance, high reliability, and high functional density of satellite-borne integrated electronics, the study was implemented on domestic LEO mobile constellation satellite-borne integrated electronic technology. Upon benchmarking foreign advanced LEO mobile constellation satellite-borne integrated electronic products, we analyzed the architecture of the domestic ones, and proposed solutions based on domestic devices; For the requirements of long service life and high reliability, the reliability analysis was carried out on several working modes with the components and parts stress analysis method, and a reliability improvement plan was proposed on the basis of software and programmable devices. Finally, we obtained a design plan of a satellite-borne integrated electronic system for LEO mobile constellation applications. With the overall performance comparable to those of advanced foreign solutions, the processing performance trebling that of existing domestic satellite-borne computers, and the 10-year reliability of 0.99999, it meets the needs of domestic LEO mobile constellation services.
