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, lower power
consumption and the option of using either an active or passive antenna.
The Navman Wireless Jupiter 31 GPS receiver module has been designed for low power
consumption in reduced signal areas at a very competitive price. The Jupiter 31 normally
acquires GPS position under low signal conditions faster than other GPS engines.
Tracking continues in areas of dense foliage or built-up inner city environments and even
indoors greater than –159 dBm.
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.
