Broadcom has just announced a new single~chip GPS solution for mobile devices that will be manufactured using the affordable 90nm CMOS process, bringing to the table superior receiver technology as well as tracking sensitivity. This receiver will full utilize the Global Locate architecture that is capable of measuring even the faintest GPS signals (as low as -162 dBm) despite being trapped inside infamous urban canyons. Power consumption is also extremely frugal, sipping no more than 15mW when navigating with one second map updates. Hope to see these new chips make an appearance in future GPS-capable devices soon.
Thanks
