GPS Receivers Extend Performance And Options

Expanding the company's SiRFStarIII-based offerings, the Jupiter 31 and Jupiter 130 GPS receiver modules boost performance levels and add more development options. Based on the Jupiter 21 architecture, the Jupiter 31 offers a number of performance and sensitivity enhancements. Features include low-power SiRFStarIII GSC3e/LP technology and power management options for minimal power consumption in all conditions, a sensitivity greater than minus -159 dBm, greater noise rejection, advanced algorithms, and the option of using either an active or passive antenna. Specifications include a temperature range from -40°C to 85°C, an altitude range of minus -305m to 18,000m, and 95% non-condensing humidity. The device weighs 25g in a 41 mm x 71 mm x 10 mm form factor. The Jupiter 130 features a 20-channel GPS receiver with integrated patch antenna and employs its own PCB for the ground plane for optimal gain. The device promises fast time-to-fix and reliable performance in all conditions including dense cities, heavy foliage, and enclosed spaces. Based on the Jupiter 30 design, the Jupiter 130 provides an upgrade path to the SiRFStarIII chipset and faster integration. NAVMAN WIRELESS NORTH AMERICA, Glenview, IL. (866) 527-9896.
