How GPS Locates You

A technology infographic explaining how GPS finds your location, drawn as a scene with three or four satellites beaming signals down to a phone on a stylized globe. Dotted signal lines and expanding range circles illustrate trilateration; numbered captions explain 'satellites broadcast time', 'phone measures delay', 'overlap pinpoints you'. A space-dark background with earth-blue and orange signal accents, clean flat vector. Bold title 'How GPS Locates You' at the top, a small crosshair pin and accuracy-meter icon.

一张技术信息图,讲解 GPS 如何找到你的位置,画成三四颗卫星向风格化地球上的一部手机发射信号的场景。虚线信号线与不断扩大的范围圆示意三点定位;编号说明写着「卫星广播时间」「手机测量延迟」「交叠锁定你」。太空深色背景,地球蓝与橙色信号点缀,干净的扁平矢量。顶部粗体标题「GPS 如何定位你」,一个小十字准星标记与精度表图标。
