FYI for anyone who has an interest in GPS at this level.

GPS baseband delivers
3-m accuracy for under $5

Device is priced about 45% lower than other comparably featured parts

Developed for portable handhelds, the 14-channel Baldur GPS baseband IC is offered as the first such device to achieve a horizontal resolution of as little as 1 m (corrected) and 3 m (autonomous) with a $5 price tag—about 45% lower than the competition. The company claims that the low-cost part will accelerate the growth of existing GPS applications, as well as enable a variety of new ones.

Vertical resolution is 5 m (corrected), and velocity is measured to within 0.1 m/s. The device can receive and process signals from 12 different tracking satellites at the same time and features acquisition sensitivities of –173 dBm and tracking sensitivities of –150 dBm. In addition, the part has two satellite-based augmentation system channels for the Wide-Area Augmentation System, European Geostationary Navigation Overlay Service, or MultiFunctional Transport Satellite Augmentation System.

Power dissipation is 70 mW under continuous operation at 16 MHz and 18 mW in power-saving mode. The part is housed in an LFBGA package. ($5 ea/100,000—available now.)
