OBC板是开展空间科学实验的实验性小卫星“立方星”的核心组件，其设计优劣对于立方星性能具有较大影响，一般的计算机应用于星载系统无法满足立方星运行时重量轻，成本低的要求。为解决这一问题，提出了基于MSP430单片机的立方星OBC板设计方案。方案选取了单片机进行嵌入式设计，具有高度集成化一体化，重量轻，成本低及效率高的优点。
OBC闆是開展空間科學實驗的實驗性小衛星“立方星”的覈心組件，其設計優劣對于立方星性能具有較大影響，一般的計算機應用于星載繫統無法滿足立方星運行時重量輕，成本低的要求。為解決這一問題，提齣瞭基于MSP430單片機的立方星OBC闆設計方案。方案選取瞭單片機進行嵌入式設計，具有高度集成化一體化，重量輕，成本低及效率高的優點。

OBC is the key device of cubesat,which is a kind of small experimental satellite adapted to the scientific experi-ments in space. Its design has a great influence on cubesat’s functions. However,the ordinary computers applying to on-board systems can not satisfy the requirements of light weight and low cost. In order to solve the problem,a design scheme for cubesat OBC based on MSP430 microprocessor is presented. The microprocessor was chosen in the scheme to conduct the embedded de-sign. The design has the advantages such as great integration,light weight,low cost and high efficiency.
