Low-power, single-chip GPS solution

6 August 2008 Telecoms, Datacoms, Wireless, IoT

Following the recent closing of its acquisition of GPS technology provider GloNav, NXP Semiconductors has released its first single-chip, assisted-GPS (A-GPS) solution, designed for use in both mobile phones and standalone personal navigation devices (PNDs).

Built on an advanced architecture, the GNS7560 is a small, low power, low cost GPS solution. In a demonstration of faith in its product, NXP has also integrated this GPS technology into its existing Nexperia Cellular System Solution 7210 for 3G.

In a package size of less than 9 mm², the GNS7560 is implemented on a 90 nm architecture and features a high performance CMOS RF front-end plus correlator engine to reduce system cost and power. Advanced power management modes reduce power consumption to less than 13 mW for one-second map updates.

The module automatically alters sensitivity and tracking based on signal strength, multipath and velocity, delivering excellent acquisition and tracking sensitivity, time to first fix (TTFF) and accuracy to ensure deep-indoor sensitivity and reliable coverage even in dense metropolitan areas. The host software for the product is structured for easy OS integration with Microsoft Windows CE, Windows Mobile and Linux standard drivers, as well as a variety of real-time kernels in support of today's Smartphone designs.
