求翻译：敏捷机动性能是小卫星技术发展的迫切需求之一，要实现其敏捷机动能力需要较大的输出力矩，但是在质量受限制的情况下，动量轮和反作用飞轮所产生的力矩已不能满足小卫星敏捷机动的功能，而控制力矩陀螺(CMG)因其小质量就可以获得较大输出力矩的特点成为敏捷小卫星首选的执行机构。是什么意思？

Agile mobility is small satellite technology one of the urgent need to achieve the agility mobility needs large output torque, but in the case of restricted mass, momentum and reaction wheel torque generated by the flywheel can not meet the small satellite agile maneuvering capabilities, and control

The agile maneuvering performance is one of smallsat technological development urgent demands, must realize its agile maneuver capability to need the big output moment of force, but in the quality in the situation which limits, the momentum wheel and the reaction flywheel produce the moment of force

Agile mobility can is small satellite technology development of urgent demand one of, to implementation its agile maneuver ability needs larger of output torque, but in quality by limit of situation Xia, momentum wheel and reaction flywheel by produced of torque has cannot meet small satellite agile
