摘要
针对传统卫星制造过程复杂,无法满足面向商业市场的微纳卫星批量化生产需求的问题,文章提出了一种"单机标准化、系统模块化、整星二度集成化"的精致微纳卫星设计理念。采用"配置精简化、结构虚拟化、功能软件化"设计方法,实现了微纳卫星"高承载、高精度、高速率、高功率"的设计,并通过"精致微纳技术试验卫星"进行了验证。针对微纳卫星传统评价方式单纯以技术指标为依据、缺乏全面性的问题,文章提出了一种面向商业市场的微纳卫星效费比评价体系,以微纳卫星质量承载比、功率承载比和通信密度比为关键因素,综合卫星制造成本,较为全面地对微纳卫星效费比进行评估,以衡量其商业市场竞争力。可为我国微纳卫星设计、制造与评价提供新的理念与方法。
Traditional satellite manufacturing is based on single-machine direct integration,usually is suitable for single-satellite development tasks which has complex process and can’t meet the bulk production requirements of micro-nano satellite on commercial market.This paper puts forward a design concept of exquisite micro-nano satellite based on the concept of “unit standardization,system modularization,second integration of whole satellite”,which adopts design methods of “configuration streamlining,structure virtualization,function realized by software”.This design concept realizes a micro-nano satellite design,which has high load,high precision,high speed and high power,to meet the competition requirements of micro-nano satellite market,and carries on the practice and verification through the “exquisite micro technology experiment satellite” project.Aiming at the problem that the traditional satellite evaluation system is simply based on satellite technical index and cannot be directly applied to commercial micro-nano satellite,this paper puts forward an evaluation system of micro-nano satellite cost effectiveness ratio for commercial market,which is more comprehensive to coordinate with micro-nano satellite products.It has been proved that this system can meet the needs of micro-nano satellite evaluation in market.The results provide a brand-new concept and method for the design,manufacture and evaluation of aerospace equipment in the field of micro-nano satellite in China.
