It achieves an advantage by outsourcing the fabrication of the devices to a specialized semiconductor manufacturer called a semiconductor foundry or "fab. developing global positioning system Global Positioning System: see navigation satellite. Global Positioning System (GPS) Precise satellite-based navigation and location system originally developed for U.S. military use. (GPS) products for the cellular handset and mobile consumer electronics device markets, today announced the GNS4540 high-performance single chip L1 A-GPS solution targeted for the cellular handset and mobile consumer electronics markets. Offering best-in-class acquisition and tracking sensitivity, time-to-first-fix (TTFF TTFF Time To First Fix (GPS) TTFF Trinidad and Tobago Football Federation (Trinidad and Tobago) TTFF Time To First Failure ), accuracy and power consumption, the GNS4540 supports both Assisted-GPS operation on GSM, WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. and CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. networks and fully autonomous operation for use in handheld consumer navigation devices and other standalone navigation systems. Featuring its proprietary DynaTrak[TM] technology that automatically adapts to the user's environments, the GNS4540 enables a seamless consumer experience that continues to work wherever they are. When other solutions dropout -- deep indoors, in urban canyons, transitioning from strong to weak signals, or from in-vehicle to pedestrian operation -- DynaTrak rapidly adjusts to the dynamic signal environment, allowing the receiver to track continuously and accurately. "As location-based services continues to grow in demand and find its way into devices, manufacturers will look to quickly bring reliable and accurate products to market while maintaining form factor and low power consumption," said Bill McLean, chief executive officer, GloNav. "Our highly integrated GNS4540 provides a turnkey GPS solution, enabling manufacturers to embed best-in-class GPS functionality into their devices while reducing overall bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. ." The GNS4540 is built upon more than 20 years of investment in 10 generations of products, the longest heritage of GPS technology investment in the semiconductor industry today, assuring customers of a reliable technology foundation that has stood the test of time. With both the GPS RF and baseband architected for ultra low-power consumption, and a complete set of power management modes, the device minimizes system power consumption and offers ultra low energy-per-fix. The GNS4540's hosted architecture shifts the non real-time critical navigation software to the host system's processor, minimizing system cost and printed circuit board size. GloNav offers software drivers for the most popular high level operating systems for handsets and other portable devices, including Microsoft Windows[R] CE, Microsoft Windows Mobile[R], Linux and a variety of real-time kernels. The GNS4540 solution eases integration, with connections required for just RF and clock inputs, power and serial interface to the host. To further speed time to market, GloNav supports the GNS4540 with full reference designs, demonstration systems, software development kits and other supporting documentation. GNS4540 samples and demonstration systems are available immediately and GloNav is accepting orders for volume production shipments commencing in the second quarter of 2007.
