As a result, some radio chips—for example, those used for the Global Positioning System, say, or for Bluetooth wireless communications—now cost as little as $1 and are the size of a matchhead.

于是，一些无线芯片，比如用于全球定位系统的芯片或者用于蓝牙无线通讯的芯片现在每个只卖1美元，而体积只有火柴头那么大。

The latest generation of Opticom gear does away with infrared in favor of a combination of cellular radio and Global Positioning System links, which can pinpoint a vehicle's location and speed.

FORBES: Greening the Traffic Lights

Each onboard ADS-B set consists of a Global Positioning System satellite navigation unit, two Pentium microprocessors, some software and a radio transmitter-receiver--not much more gear than you would find behind the dash of a new Cadillac.

FORBES: Free flight

The study, the first of its kind to use the satellite-based global positioning system to provide the animals' locations, involved tagging 14 African elephants with sophisticated radio collars and monitoring their movements for several months.
