说到GPS,人们并不陌生,它是美国研制的一种全球卫星导航定位系统。而对于俄罗斯的“格洛纳斯” (GLONASS Global Navigation Sat- ellite System)也许知道的人就不多了。其实,“格洛纳斯”与 GPS 类似,由 24颗卫星组成,也是一种全球卫星导航定位系统,军民两用。为了抗衡美国的 GPS,避免将来在军事上受制于人,俄罗斯近来开始联合印度一起打造自己的全球卫星导航定位系统。 Speaking of GPS, people are no stranger to it. It is a global satellite navigation and positioning system developed by the United States. There may not be many people who may know about Russia's GLONASS Global Navigation Sat ellite System. In fact, “GLONASS” is similar to GPS and consists of 24 satellites. It is also a global satellite navigation and positioning system, military and civilian. In order to counter the U.S. GPS and avoid being controlled by the military in the future, Russia has recently started to work together with India to build its own global positioning satellite navigation system.
