Galileo-ready GPS chip featuring an acquisition performance of less than one second to be unveiled at 3GSM World Congress


Thalwil, Switzerland, 31 January 2007 – u-blox AG, the Swiss provider of GPS receiver technology, will unveil u-blox 5, a GPS and Galileo-ready chip featuring an acquisition performance of less than one second, at the 3GSM World Congress in Barcelona, 12-15 February.

The new technology boasts an acquisition and tracking sensitivity of -160 dBm that enables indoor coverage, a 50-channel engine and a power consumption of less than 50 mW. Its energy efficiency and tracking sensitivity make it ideal for GPS-enabled mobile phones and other battery-operated portable devices that operate in difficult indoor environments like shopping malls, train stations and urban canyons.

u-blox 5’s ultra-fast acquisition time is due to its 50-channel architecture with over 1 million correlators and separate acquisition and tracking engines, capable of massively parallel searches. A built-in power management unit features a DC/DC converter that optimizes power use across a single voltage source. The chip’s ultra-low power needs ensure long battery times for PDAs, smart phones and other battery-operated handheld devices.

u-blox 5 has a fractional N clock synthesizer that supports the common cell phone reference frequencies. Moreover, u-blox’ new generation supports assisted GPS (A-GPS) services such as AssistNow and OMA/SUPL standards and exceeds performance requirements for international A-GPS standards including 3GPP TS 25.171, TIA 916 and E911 Phase II. u-blox 5 GPS receivers come in single chip and chipset packages.

A highly integrated architecture keeps costs to a bare minimum by reducing the bill of materials to as few as 17 passive external components and keeping the footprint small. The cost-optimized UBX-G5010 single chip has a 56-pin QFN package that measures a mere 8 x 8 mm. Customers who prefer chipsets with an optional Flash memory can combine the 9 x 9 mm UBX-G5000 100-pin BGA baseband chip and the 4 x 4 mm UBX-G0010 24-pin QFN RF front-end. Both the single chip and the chipset support passive antennas with their integrated low-noise amplifier.

The chips’ software contains an innovative jamming suppression mechanism that automatically filters signals from interfering sources, thus maintaining high GPS performance no matter what the environment.

A robust multipath detection and elimination mechanism endows u-blox 5 chips with best-in-class navigation in urban canyons. u-blox 5 products will be capable, via a simple software upgrade, of receiving and processing L1 Galileo signals once they become available. The combination of GPS and Galileo signals will bring even better coverage, reliability and navigation accuracy.
