"Airwave1 is a complete GPS L1 receiver and it is the first product to benefit from Air's Always–On™ GPS technology.
Airwave1 is designed to support geotagging in digital cameras. To support this application, location information needs to be provided instantly when the user takes a photograph. With Airwave1 inside, the camera is continuously aware of its location and so it can immediately tag a photograph with its location – as soon as it is taken.
Airwave1 is a complete system for continuous location in cameras, comprising RF, analogue and digital signal processing hardware, a microprocessor and all embedded software necessary to provide a complete 'antenna to coordinates' solution in a single–chip."
