CellGuide has unveiled the newest addition to its line of high performance GPS productsthe ACLYS solution. The ACLYS chip, together with its associated host-based software, is said to lead the market evolution from existing standalone GPS products to more highly integrated solutions.

ACLYS replaces dedicated GPS silicon by leveraging mobile processors or other wireless components inside the mobile device, to provide GPS functionality. Implementation of the ACLYS solution enables mass-market device manufacturers to implement GPS at break-through cost, while providing superior, best-of-breed GPS performance.

Unlike other host-based solutions, ACLYS promises to deliver consistently high, uncompromising GPS performance in all modes of operation (autonomous and assisted-GPS). The ACLYS chip provides -160dBm sensitivity and employs proprietary navigation algorithms for accurate navigation even in the most demanding urban environments. Advanced power management reduces power consumption to less than 10mW in tracking mode. ACLYS also operates with CellGuide's technology to ensure fast startups even when no cellular network is available. Using an advanced RF CMOS process, the ACLYS chip is available in a 5mm x 5mm x 0.9mm QFN-32 package, making it a well-suited solution for mobile devices.

As a pioneer in host-based GPS/GNSS products, CellGuide has successfully integrated its solutions into various third party ARM/DSP-based processors including those from Freescale Semiconductor (MX series), Marvell (PXA series), NEC Electronics (MP series), Samsung Electronics (S3C24xx and others), TI (OMAP) and others.

The ACLYS host-based software runs on operating systems such as Windows CE, Windows Mobile, Symbian, eLinux, Thread-X, Nucleus and u-Cos.
