去年11月,美国陆军在坎贝尔对导航星全球定位系统(GPS)进行了现场试验。据陆军准将霍华德·格雷夫斯在美国宇航协会会议上讲,试验时,在UH-60布莱克霍克直升飞机中用全球定位系统终端进行导航,使这架直升机能准确地飞行在“正确的航线上”。格雷夫斯说,试验目的是确定导航星终端是否能稳定地供部队使用。他说在 In November last year, the Army of the United States conducted a field trial of navigation satellite global positioning system (GPS) at Campbell. According to Army Brigadier General Howard Graves, speaking at the meeting of the American Space Society, the pilot was navigating with a Global Positioning System terminal on a UH-60 Black Hawk helicopter to enable the helicopter to fly accurately at the “correct Route ”. Graves said the purpose of the experiment is to determine if the navigation satellite terminal can be used stably for troops. He said yes
