基于随遇测控的轻量级卫星平台电气系统一体化设计

Integrated Design of Electrical System of Lightweight Satellite Platform Based on Random TT&C

由于轻量级卫星平台上资源紧张,为提高卫星上资源利用率,综合质量、体积和功能等多方面需求,研究提出了一种基于随遇测控的一体化电气系统,将各功能做模块化设计,将各功能板卡集成在卫星的舱体内做机箱化构型,各系统通过标准化总线实现信息交互。此外,在机箱内增加随遇测控功能,在实现电气一体化设计的同时,降低了测控功能设计的复杂度,提高了测控可靠性。

Due to the shortage of resources on the lightweight satellite platform,in order to improve the utilization of resources on the satellite,and to meet the requirements of mass,volume,function and other aspects,an integrated design of electrical system based on random access TT&C is proposed.Each function is modularized,and each function board is reintegrated in the satellite cabin for a chassis configuration.Standardized bus is realized through systemic information interaction.Meanwhile,the random access TT&C function is added in the cabinet,which reduces the complexity of measurement and control function design and improves the reliability of measurement and control while realizing the electrical integration design.
