Navman, a designer and manufacturer of world-class global positioning systems (GPS), communication and marine products and components, announced the latest addition to its highly successful Jupiter GPS module product line. The new Jupiter 20 surface mount receiver, with SiRFstarIIe/LP chipset, offers a number of significant enhancements to its sibling Callisto, allowing system designers and integrators to apply the technology to a wider array of demanding applications. For optimal design flexibility, the Jupiter 20 receiver is available in 3 configurations: the standard Jupiter 20 for most applications; the high-sensitivity Jupiter 20 S for general navigation in low GPS signal situations (available with SiRF XTrac software), and the Dead Reckoning (DR) enabled Jupiter 20 D for high-accuracy vehicle tracking applications contending with urban environments and tunnels.
Key features of the Jupiter 20 include a compact form factor (25.4mm x 25.4mm x 3.0mm); upgradeable flash memory; state of the art algorithms for optimized use in urban environments; improved jamming immunity; horizontal position accuracy of better than 3m CEP without differential aiding; integrated gyro interface for Dead Reckoning option; and integrated LNA for active and passive antenna support. Additional features include: standard XTrac and DR options; 1PPS output with better than 1 Âµsec timing accuracy; power management options to reduce current consumption - as low as 35mA; GPS fix output; 7 GPIOs controlled by serial command; and WAAS/EGNOS compatibility. Key features of Navman's previously released surface mount receiver, Callisto, include a small form factor (19.2mm x 17.7mm x2.5mm); low power consumption (52 mA); 8 MB of Flash memory; 1.5 Âµsec timing accuracy; and power management capability ensuring low current consumption. Navman Jupiter 20 and Callisto receivers are both currently shipping in production quantities.
