Germany’s top chipmaker Infineon and Seiko Epson today presented a new single-chip GPS receiver that boasts the highest sensitivity and smallest footprint on the market. The so-called XPOSYS chip will mainly be used in cell phones with built-in navigation functions.

The companies said sensitivity now stands at 165dBm, 5 dBm higher than the previous model, allowing for exact positioning even within buildings. With a footprint of 26 sq.-mm, the XPOSYS chip is also the smallest of its kind in the world. In addition, power consumption has been cut in half.

According to the official press release, mass production is scheduled to start by mid-2009.
