据报道,五角大楼的研究机构公开了装有安全软件系统的新型无人机,以防止黑客入侵该机的控制和导航系统,号称世界最安全的无人机。美国《防务新闻》网站近日报道,美军正在研制新型导航定位设备,以替代现在广泛使用的GPS卫星定位导航系统。报道称,GPS之所以被美军诟病,主要是由于该系统过于依赖脆弱的天基卫星系统。卫星在战时极易被干扰、破坏,或受到网络攻击,自身安全性难以得到有效保证。美国军事专家担心的是,尽管 According to reports, the Pentagon’s research institute has released a new type of unmanned aerial vehicle equipped with a safety software system to prevent hackers from intruding on the control and navigation system of the aircraft, known as the safest UAV in the world. The U.S. Defense News website recently reported that the U.S. military is developing a new type of navigation and positioning equipment to replace the GPS satellite positioning and navigation system now widely used. Reported that the reason why GPS was criticized by the U.S. military, mainly because the system is too dependent on the fragile space-based satellite system. In the wartime, satellites can easily be interfered, damaged or attacked by cyber and their own security can hardly be effectively guaranteed. What the U.S. military experts worry about is that though
