1.0 Introduction
Navman’s Jupiter 32 xLP extra low power receiver module has been designed to address
markets where performance, size, power and flexibility are very important. A miniature
successor to the ultra sensitive Jupiter 30, the Jupiter 32 xLP is Navman’s smallest, lowest
power consumption, autonomous, fully featured GPS receiver yet.
The Jupiter 32 xLP offers the ultimate in high sensitivity GPS performance, capable of both
autonomous and aided modes of operation. The module has advanced miniature packaging
and a Land Grid Array (LGA) footprint with unique integration features for high volume, low
cost and low power applications where tighter integration is required.
Incorporating the highest specification components available, the Jupiter 32 xLP can track
down to –159 dBm and offers unparalleled accuracy and extremely fast fixes even under
attenuated conditions such as in built-up urban areas, dense foliage, indoors or while subject
to challenging temperature profiles. The module provides a miniature 20-channel receiver that
continuously tracks all satellites in view and provides accurate positioning data.
Featuring active or passive antenna support, Write-to-Flash configuration, power saving
modes, SiRFInstantFix support and full multi-mode aiding capability, the Jupiter 32 xLP is
highly suited for all battery powered applications or high-end track and trace applications.
2.0 Technical description
Navman has enhanced the architecture of the SiRF GSC3f chipset by adding carefully
selected key components including TCXO and LNA. This ensures frequency stability, improved
sensitivity at low level signals down to –159 dBm, lower power consumption and a faster TTFF
(Time To First Fix). The GSC3f chip integrates baseband, RF sections and Flash memory,
thereby reducing power consumption and size. Integrated 4 Megabit flash memory gives the
user the ability to store configurations permanently.
By providing separate on-board regulators, the Jupiter 32 xLP allows operation over a wide
input voltage range, down to 3.0 VDC. This gives OEMs the ability to design with a single
voltage supply that consumes less power.
The 20-channel architecture with more than 200 000+ effective correlators provides rapid
TTFF under all start-up conditions. Acquisition is guaranteed under all conditions due to higher
sensitivity and the ability to use multi-mode aiding.
Protocols supported are selected NMEA (National Marine Electronics Association) data
messages and SiRF Binary.
2.1 Product applications
The Jupiter 32 xLP is designed specifically for applications where rapid TTFF and operation
under low signal levels along with a small form factor are primary requirements. The module
offers high performance and maximum flexibility in a wide range of OEM configurations.
The high sensitivity of the module makes it ideal for:
