GPS Receiver Slashes Power Consumption

The Swift B2 LP, a GPS receiver based on the SIRFstar IIe-LP chipset, aims to cut power consumption by as much as 50% over existing units, extending battery life for mobile devices such as cell phones, personal locators, and handheld devices. When operating in TricklePower mode, the receiver can reduce power dissipation by up to 98%, further addressing the demands of the consumer GPS market. Other features include a Wide Area Augmentation System (WAAS) and Coast Guard beacon support (DGPS). In addition, the SingleSat feature provides positioning information during intervals when one satellite is visible, as in an urban canyon, while SnapLock acquisition renews satellite positioning within one-tenth of a second after emerging from a blocked region—this re-establishes position accuracy when vehicles emerge from an overpass. Further, FoliageLock reception permits the Swift B2 LP to operate with low signal levels, such as under tree canopies. The device measures roughly the size of a postage stamp (1" x 1.25" x 0.28") and incorporates a board-to-board data interface connector. Additional features include 4, 8 or 16 Mbits of flash and an integrated real-time clock. AXIOM NAVIGATION INC., Costa Mesa, CA. (714) 444-0200.
