The simulation result shows that the variable structure automatic pilot for KKV is fast and has high attitude control accuracy, which satisfies the requirements.

数学仿真表明，变结构自动驾驶仪具有很好的快速性和很高的姿态控制精度，可以满足动能拦截器对姿态控制的要求。

Since last time China attacked a satellite in 2007(also on 1.11) they've made great improve. GMD and the kkv(kinetic kill vehicle) capability is far beyond that scale.

自从中国上次在2007年用导弹击落卫星（也是1月11日），中国已经取得了很大的进步。

As U.S. intelligence revealed last week, the destructive intercept was performed by a kinetic-kill vehicle (KKV) launched onboard a medium-range ballistic missile.

These include, in addition to the ballistic missile-delivered KKV system tested earlier this month, China's acquisition of microsatellites (and, according to some, even nanosatellites).
