1 基本概念

立方体卫星的概念在1999年由加州州立理工学院(Cal Poly)和斯坦福大学联合提出,目的是提

供一种标准的纳卫星设计,从而降低成本、缩短研制时间,更便于发射入轨,并保持较高的发射频率。

立方体卫星每个标准尺寸单元称为1U,其内核尺寸为10cm×10cm×10cm,质量不超过1.33kg,卫星可

以按照一定的规则进行规格递增,常见的立方体卫

星规格包括1U、1.5U、2U、3U等,各规格卫星的大小如图1所示,其具体尺寸如下[1-4]:结构外形切面方向尺寸(100±0.1) mm;1u立方体卫星纵向尺寸小于(113.5±0.1) mm;3u立方体卫星纵向尺寸小于(340.5±0.3) mm;卫星质心与形心偏差在20mm以内。1999年,美国加州理工学院和斯坦福大学就

制订了立方体卫星及其分离机构的标准,用于规范立方体卫星的设计。
