New ultra-sensitive GPS chip

There are a few new GPS receivers on the market with the spankin' new SiRFstarIII chipset. This new chip allows for fast time-to-first-fix (TTFF) and is sensitive to very low power signals -- so low, in fact, that some claim GPS reception indoors and even better reception under canopies and in dense urban areas. Some of the new receivers on the market that include the Garmin GPSMap 60Cx and the Bluetooth Globalsat BT-338.
