微小卫星三机异构一体化计算机设计
Design on Hybrid Tri-redundant Integrated Computer for Micro-satellite
摘要
Abstract
To satisfy different requirements, different computer systems are adopted for on-board computer for launch vehicle and satellite. To overcome the resource waste and low reliability for the design method, a new design method of on-board integrated computer for satellite is presented. A hybrid tri-redundant system is designed. At the launching phase, the computer for launch vehicle based on digital signal processor (DSP) acts as a host processor, while the time-varying computer based on FPGA is used as a spare. The satellite platform computer based on ERC32 acts as a host computer, and the time-varying computer is used as a spare after reconfiguration in orbit. The reliability for the on-board computer for launch vehicle is improved. The comprehen- sive management for the on-board computer for satellite is advanced. The expansibility and adaptability is increased.关键词
