In this case, a leading possibility is that the signal originates from an unusual modulation between a GPS satellite and an unidentified Earth-based source.

在这种情况下，最主要的可能性是这道信号来源于一个一颗GPS卫星和未确认的地球发射源之间的不寻常的调制信号。

That way, the device responds quicker than it would if it had to download the data for triangulation each time from Apple, or wait a minute or so for the faint signal from a passing GPS satellite.

通过这种三角定位的方式，如果设备必须要从苹果上下载东西的时候，它每次的响应速度会比较快，否则的话，需要等待一分钟左右，以便接收经过的GPS卫星发出的微弱信号（进行定位）。

Hallelujah the phone appears to be alive, still able to gasp out a GPS signal, and only 1.3 miles from home!

We tested the device indoors -- located near a window, it picked up a GPS signal easily, and transmitted its location to a map within the iOS app even as we walked 100 or so feet away, past several walls.

It's designed by former Nokia engineers who claim they've used their mobile skills to make the Leikr catch a quicker GPS signal, connect directly to a cloud-based, Endomondo-integrated exercise portal using WiFi and Linux-based software, and at the same time stick to a smartphone-like 10mm thickness.
