猫捉老鼠：GPS jamming 导致海马士失效

Russia has been thwarting US-made mobile rocket systems in Ukraine more frequently in recent months, using electronic jammers to throw off its GPS guided targeting system to cause rockets to miss their targets, multiple people briefed on the matter told CNN.

Ukrainian military officials, with the US’ help, have had to come up with a variety of different workarounds as it continues to use the High Mobility Artillery Rocket System (HIMARS) which has been perhaps the most revered and feared piece of weaponry in Ukraine’s fight.

But in recent months, the systems have been rendered increasingly less effective by the Russians’ intensive blocking, five US, British and Ukrainian sources tell CNN, forcing US and Ukrainian officials to find ways to tweak the HIMARS’ software to counter the evolving Russian jamming efforts.

高科技武器太依赖GPS了。以前有报道，俄罗斯应用同样的GPS jamming影响了乌克兰的Starlink 卫星通讯。因为最新科技Starlink本身不容易干扰，但是Starlink通讯需要GPS精确 时间信号，而俄罗斯通过干扰GPS而导致乌克兰Starlink通讯不正常。

俄罗斯科技还是不错的，通过打战不断进步，找到最新科技的要害。战争一开始，土耳其无人机帮乌克兰大占优势，后来俄罗斯也找到了办法，土耳其无人机基本就退出了战场。

这场战争也突出了高科技武器的缺点，特别是对于世界前几名的国家,那种靠高科技虐菜伊拉克的战法对科技和军事大国基本不可能。

战争也是其他国家，包含中美如何应付高科技武器和如何研发高科技武器提供了难得的教训

临阵修改软件，fix bugs.
Oh my God!
