Navman has announced several enhancements to its Jupiter 30 and Jupiter 32 GPS modules. The company reports that the modules now demonstrate a 25% reduction in overall power consumption and initial acquisition power consumption reductions of approximately 35%. They are well suited for use in battery-powered applications as well as those in reduced signal areas.
The Jupiter 30 and 32A are designed with maximum peak power draw of 57mA and dynamic power consumption in order to address weak signal environments, increasing acquisition and tracking when signal strength is poor.
The software design of the Jupiter 30 and 32 employs a dynamic time model that optimizes performance and power requirements when in GPS signal acquisition mode and enhances shared battery power supply life in mobile applications. Steady state tracking power requirements in strong signals are 25% lower than the previous versions of the Jupiter line.
Based on the new SiRFStarIII GSC3 LP chipset, additional improvements include improved noise immunity; RTC, PLL and RF amplifier noise immunity; updated default almanac; improved SBAS acquisition and increased immunity to CW jammers on SBAS acquisition and overall improved signal acquisition and tracking.
Both the Navman Jupiter 30 and 32 feature user-selectable, optimizable navigation modes including General Use, Automotive, Pedestrian and optimized Low Power modes designed to suit numerous applications. The devices deliver indoor position fix and tracking capability of better than -159 dBm, and include more than 200,000 effective correlators for superior acquisition performance in the weakest signal conditions.
Acquisition fix performance is less than 1 second for a hot start, 32 seconds for a warm start, and 34 seconds for a cold start. Jupiter 30 is housed in an industry standard 25.4mm x 25.4mm x 3.0mm form factor with a weight of 4.0 grams. The Jupiter 32 measures 15.0mm x 17.0mm x 2.7mm form factor and weighs 2.0 grams.
The Navman Jupiter 30 and 32 GPS modules are available in production quantities.
