A new technology being developed by Microsoft Research could lower the high GPS power requirements. According to reports, Cloud-Offloaded GPS (CO-GPS) would cut GPS power requirements by 99 percent by transferring most of the work associated with calculating a precise location to the cloud. Microsoft Research has found that using CO-GPS would allow for constant sensing with one measurement per second granularity for one year and a half using only two AA batteries. Additionally, CO-GPS works much faster than the current GPS; what would normally take a smartphone 30 seconds to calculate its precise location, takes only milliseconds for the new system. Read More
