1.0 Introduction
The Jupiter 31 is a 20 channel GPS receiver module based on the Jupiter 21 form factor
that is significantly enhanced to take advantage of the SiRFStar III architecture. The
Jupiter 31 offers a substantial increase in sensitivity, faster time to fix and lower power
consumption. The Jupiter 31 acquires GPS positions faster under low signal conditions than
other available GPS engines. Tracking continues in areas of dense foliage or built-up inner city
environments and even indoors of sensitivity of greater than –159 dBm with the option of using
either an active or passive antenna.
2.0 Technical description
The Jupiter 31 is a single board GPS module solution intended for a wide range of OEM
products, and provides an easy migration path from the Jupiter 21.
The highly integrated receiver incorporates and enhances the established technology of the
SiRF StarIII GSC3e/LP chipset. With a high navigation sensitivity, the Jupiter 31 is designed
to meet the needs of the most demanding applications and environments. The interface
configuration and form factor allows incorporation into many existing devices and legacy
designs.
Using the new and highly integrated GSC3e/LP from SiRF and carefully selected key
components including TCXO, LNA and Flash, the Jupiter 31 offers faster acquisition, a wider
operating voltage range and greater noise rejection than leading competitors’ products using a
similar architecture. The Jupiter 31 receiver decodes and processes signals from all visible GPS
satellites. These satellites, in various orbits around the Earth, broadcast RF (radio frequency)
ranging codes, timing information, and navigation data messages. The receiver uses all
available signals to produce a highly accurate navigation solution. The 20-channel architecture
provides rapid TTFF (Time To First Fix) under all start-up conditions. Acquisition is guaranteed
under all initialization conditions as long as available satellites are not obscured.
Satellite-based augmentation systems, such as WAAS and EGNOS, are supported to improve
position accuracy.
Protocols supported are selected NMEA-0183 (National Marine Electronics Association) data
messages and SiRF binary, including: latitude,longitude, elevation, velocity, heading, time,
satellite tracking status, command/control messages
2.1 Product applications
The Jupiter 31 is designed specifically for applications where rapid TTFF and operation under
low signal levels are primary requirements. The module offers high performance and maximum
flexibility in a wide range of OEM configurations such as asset tracking, fleet management and
marine and vehicle navigation products. The high sensitivity of the module makes it particularly
ideal for:

navigation systems – where athermic glass, or an unsuitably positioned antenna inside the
vehicle will reduce visibility and signal strength
vehicle and people tracking devices – where satellites are obstructed by partially covered
parking garages and walkways; Jupiter 31 will continue tracking indoors
marine buoys – where multipath and unstable sea conditions make satellite visibility
irregular
asset tracking – where construction machinery is located in covered yards and areas of
dense foliage
