Cloud-Powered GPS Chip Slashes Smartphone Power Consumption
http://j.mp/10kc8O3 (MIT Tech Review)
"Microsoft researchers reduced that power consumption dramatically by
offloading some of the work to the cloud. Jie Liu, a principal
researcher at Microsoft Research, and his team developed a GPS system
that collects only a few milliseconds of the most crucial information
from satellites. This data is then combined with other important
information from public, online databases, such as satellite
trajectories and Earth elevation values, to calculate the device's
past locations. But the data fusion and location calculations happen
on a remote server."

There are potentially significant privacy-related implications to this
approach, of course.
