The tiny FS Oncore module from Motorola consumes just 70mW whilst providing one position fix per second, and is designed to operate even with weak GPS signals.
To make the chip simpler, and therefore easier and cheaper to produce, the firmware is stored on the host device and retrieved when the chip is powered up.
Applications could include PDAs and maps that show real time navigation, position “stamping” in digital cameras, theft recovery, and mobile phones that can locate their position and find contacts and services nearby. The size of the unit means that it manufacturing companies will be able to use it in inventory tracking applications, and the low cost will help in making GPS units in cars more affordable.
