Trimble today introduced a thumbnail-sized, surface-mount, high sensitivity GPS receiver called Copernicus II. The idea with Copernicus II is to enable manufacturers to easily integrate GPS to a mobile device with minimal impact on its size or battery life at a very economical price. The new module can be used in portable handheld, battery-powered applications such as Bluetooth appliances, sport accessories, personal navigators or cameras.
Copernicus II features a 12-channel GPS receiver in a 19mm x 19mm x 2.5mm form factor and can be sensitive to detect signals even at -160dBm. It consumes 120 milliwatts of power on average when continuous tracking so it is pretty energy efficient too.
The Copernicus II GPS receiver is expected to be available in the third quarter of 2008.
