卫星指路

        你的手机上有没有GPS？去到一个陌生的地方，你如何辨别东南西北？你可知道GPS并非唯一的定位系统，而各大强国都在努力拥有自己的卫星导航？你更信任车载导航仪，还是自己脑子里的路和方向感？

There is no area of commerce, industry, agriculture, transportation in Britain that is not now dependent upon GPS and if we lose GPS, we lose critical services in all of those areas.

In cars, in ships, in planes, in our phones, we'll be lost without sat nav. It's amazing - some might say alarming - just how rapidly it sent us off in a new direction, away from self-reliance towards technological dependence, which would be fine if GPS and its sister systems were all utterly dependable. But they're not, and that could have dangerous, potentially disastrous consequences. We'll get onto what those are in due course. But before we set off, it might help to get our bearings.
Professor David Last is a former president of the Royal Institute of Navigation.
Well, GPS is the global positioning system. It's a satellite system whose job is to let us measure where we are anywhere on earth. Set up by the US military, and now of course it's used by civilians. It's what drives our car navigators, our sat navs. GPS is American. In Europe we have a system called Galileo, which is being created at the moment. The very first satellites are up and it's just beginning to work. The Chinese have their own system, or Compass Beidou. The Russians have their system and the Japanese are developing a system.在当今英国，商业、工业、农业、交通各领域无不依赖GPS，一旦没了它，我们就会在所有这些领域中失去至关重要的服务。

汽车里、轮船上、飞机上、手机中，如果没有卫星导航系统，我们就会迷失方向。它如此迅猛地将我们送往一个全新的方向，不再依靠自己，而是依赖于技术，这真是无比神奇，但也有人会说这令人警醒。如果GPS及其协同系统都完全可靠，这固然不错。但事实并非如此，而这也就可能带来危险、甚至可能是灾难性的后果。我们稍后会讨论这个。不过在此之前，先了解一些情况会有所帮助。
戴维·拉斯特教授是皇家导航学会的一位前任主席。
嗯，GPS就是全球定位系统。它是一个卫星系统，其功能是让我们在地球上任何地方都能测量自己的位置。它由美国军方建立，不过如今当然已用于民用。是它驱动了我们的车载导航仪和卫星导航系统。GPS是美国的。在欧洲，我们有一个名为伽利略的系统，目前正在创造过程中。第一批卫星已经上天，它刚刚开始工作。中国人有自己的系统，北斗卫星导航系统。俄国人也有自己的系统，而日本人的系统正在开发中。
