The GPS satellites orbiting our planet send out time coded messages.

环绕地球运行的 GPS 卫星群传递出时间编码信息。

At any given time, there are several GPS satellites orbiting overhead at a distance of about 11,000 miles.

在任何一个特定时间，总有若干颗全球定位系统的卫星在11000英里的高空绕地球运行。

Alterations in the field will mess with critical human systems, such as the GPS satellites that help us navigate.

磁场变化会干扰重要的人类系统，比如帮助我们导航的GPS卫星。

Moving on to communications, very soon, cars will be linked to GPS satellites, so they'll do all the driving for you.

至于通讯系统，不久汽车将会连接卫星定位系统，这样它们就可以为你开车了。

Any major solar storm could threaten Global Positioning System (or GPS) satellites which are critical to modern life from driving cars to flying planes.

任何大型太阳风暴都可能威胁到全球定位系统卫星，这些卫星对现代生活从驾驶汽车到飞行飞机都至关重要。

Even though solar storms can cause problems on Earth by disrupting GPS, satellites and the power grid, the one hitting now is relatively minor.

尽管太阳风暴会扰乱全球定位系统、卫星和电网，从而给地球带来问题，但目前的太阳风暴影响相对较小。

Starts with GPS, satellite systems, to tell the engineer precisely where he is at all times and to tell other trains where his train is.

从全球定位系统到卫星系统，它们都能够准确，并且实时地通告列车司机自己的方位，并能够向其他列车通告自己的位置。

If one GPS satellite is struck, it affects basic navigation; airplane routing; and time synchronization for banking and finance.

如果一颗GPS卫星被击中， 就会影响基本导航； 飞机路线；以及银行和金融的时间同步。

Around the world, people record their daily walks, runs, bike rides, with devices equipped with location tracking software which relies on GPS satellites circling the earth.

在世界各地，人们用配备有位置跟踪软件的设备记录他们每天的步行、跑步、骑行，这些设备依靠覆盖地球的全球定位系统。

It's not a big effect, but it's big enough that if we didn't compensate for it when you know, computers on earth talk to the GPS satellites.

这不是一个很大的影响，但它足够大，如果我们不进行校对，那地球上的计算机与 GPS 卫星通信时就会发生时差。

Well, for one thing without general relativity we wouldn't have GPS, because GPS satellites are much farther away from the earth and then we are here on the surface or close to it.

如果没有广义相对论我们就没有 GPS，因为 GPS 卫星离地球很远，而我们在地球表面或接近地球。

And as a result, we feel the Earth's gravity warp time more than the satellites do and so the clocks on GPS satellites run at a different speed than the clocks on earth.

因此，我们比卫星更能感受到地球引力对时间的扭曲，所以 GPS 卫星上的时钟运行速度与地球上的时钟不同。

The system is owned by America's government and operated by its air force, which means American officials could decide-say, in a conflict with China to switch off or degrade the signals coming from GPS satellites.

这一系统归美国政府所有，由美国空军运营，这意味着美国官员可以决定关闭或降级来自GPS卫星的信号，比如在中美发生冲突时。
