卫星设计寿命-
卫星的设计寿命必须要大于卫星在轨工作寿命。
The artificial satellite design life-span must need greater than artificial satellite in the orbit working life .

但是由于超低轨道卫星轨道高度较低，与传统的低轨卫星相比，其受到的气动力和气动力矩要高出几十个数量级，导致超低轨道卫星的设计寿命都比较短。
However , due to its low altitude . Ultra-low-Orbit satellite faced gas aerodynamic forces that moments of magnitude higher compared to traditional satellites . Lead to the design life of ultra-low-orbit satellites is short .
