低轨星座卫星快速开发与验证方案设计

Rapid Development and Verification Scheme Design of LEO Constellation Satellite

针对低轨星座卫星快速开发与验证需求,提出试验星+工程星+接口验证平台(VPI)并行研制验证方案。通过工程星研制,对卫星结构、总装设计及供电主通道、推进贮供主通道等设计进行验证,支撑试验星设计优化与结构投产;VPI对星上电子单机接口、星上软件等进行迭代验证。通过试验星研制,对低轨星座卫星功能性能全面验证,确定星座卫星基线。该方案经多颗卫星实施验证,有效提高了低轨星座卫星验证效率。

Aiming at meeting the rapid development and verification needs of LEO(low earth orbit)constellation satellite,the parallel development and verification scheme of engineering satellite model and a VPI(verification platform interface)and experimental satellite is proposed.Through the development of engineering satellite model,the design of structure subsystem,assembly and the main design of power supply and propulsion subsystem are verified to support the optimization of experimental satellite design and the commissioning of main structure.VPI validates of equipment electrical interface and software.Through experimental satellite development,the functional performance of LEO constellation satellite is comprehensive verified,and the baseline of satellites is established.The verification scheme is implemented in satellites,and is proved that it can effectively improve the verification efficiency of LEO constellation satellite.
