The Jupiter 31 single-board module brings the latest in GPS signal acquisition and advanced power management performance to existing system designs.

Navman Wireless OEM Solutions has released the Jupiter 31 and the Jupiter 130 GPS receiver modules.

Providing SiRFStarIII performance, the new models expand Navman Wireless' range of GPS solutions.

The Jupiter 31 single-board module brings the latest in GPS signal acquisition and advanced power management performance to existing system designs, allowing OEM manufacturers to develop powerful location-specific products.

The device offers optimal GPS operation capabilities in various signal strength environments, including indoors and other low-signal areas.

Delivering a wider operating voltage range and greater noise rejection than competitors offering similar architectures, the Jupiter 31 gives system designers the freedom to integrate the device in a broad variety of applications.

The Jupiter 130 features an onboard 20-channel GPS receiver with an integrated patch antenna, eliminating the need for an external RF antenna.

It uses its own PCB for the ground plane for optimal gain.

The device provides fast time-to-fix and superior performance in densely built cities, heavy foliage and enclosed spaces.

Based on the Navman Wireless Jupiter 30 design, the Jupiter 130 provides an upgrade path to the SiRFStarIII chipset and faster integration of GPS functionality into manufacturers' systems without antenna integration.

Key features of the Jupiter 31 GPS receiver module include low-power SiRFStarIII GSC3e/LP technology and power management options for minimal power consumption.

Other features include increased sensitivity (greater than -159dBm); greater noise rejection; algorithms for optimal performance; fast GPS acquisition in low-signal strength areas, and the option of using either an active or passive antenna.

Operating specifications include a temperature range of -10 to 60C, an altitude range of -305 to 18,000m and 95% noncondensing humidity.

The device weighs 25g, has a 41 x 71 x 10mm form factor and meets FCC Part 15 (class B), EN 55022 (class B) and RoHS specifications.

The Jupiter 130 is a 20-channel GPS module with over 200,000 effective correlators.

Also featuring the SiRFStarIII GSC3e/LP chipset, the Jupiter 130 is a highly accurate 3.3V module that incorporates a fully-integrated, embedded antenna and carrier-aided tracking in a 30 x 30 x 8mm form factor.

Hot start acquisition performance is one second and cold start performance is typically 34 seconds.

Operating specifications include a temperature range of -10 to 60C, an altitude range of -305 to 18,000m and 95% noncondensing humidity.

Both the Jupiter 31 and Jupiter 130 support ephemeris push, which assures hot start performance at all times, including weak conditions and moving starts.

Ephemeris push enables the uploading of live ephemeris data to the receiver from application servers.

The ephemeris is typically valid for four hours until the live ephemeris is downloaded or new ephemeris data is provided.
