Datasheet
1.0 Introduction
Navman’s Jupiter 3-30 extra low power receiver module offers the ultimate in high sensitivity GPS performance and low power
consumption, capable of both autonomous and aided modes of operation.
The Jupiter 3-30 acquires GPS position faster under low signal conditions than all previous Jupiter receiver modules and can
continue tracking in areas of dense foliage, built-up inner city environments and even indoors.
The module provides a 20-channel receiver that continuously tracks all satellites in view and provides accurate positioning data.
2.0 Technical description
By providing separate on-board regulators, the Jupiter 3-30 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 3-30 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.
•
avigationsystems
– where athermic glass, or an unsuitably positioned antenna inside the vehicle will reduce
n
visibility and signal strength
•
vehicleandpeopletrackingdevices
– where satellites are obstructed by partially covered car parks and walkways;
Jupiter 3-30 will continue tracking indoors
•
marinebuoys
– where multipath and unstable sea conditions make satellite visibility irregular
•
assettracking
– where construction machinery is located in covered yards and areas of dense foliage
2.1.1 Compatibility
The Jupiter 3-30 is the successor to the established Jupiter 30 xLP, sharing the same form factor (25.4 x 25.4 mm) and
electrical compatibility. This provides a low risk migration path for existing users requiring greater sensitivity, lower
power consumption and a faster fix.
Refer to section 7.0 for further information about compatibility between the modules.
Note that the NMEA protocol used on the Juipiter 3-30 is not backwards compatible to the Jupiter 30 xLP. The
NMEA protocol has been upgraded from version 2.2 to version 3.0.

Navman has enhanced the architecture of the SiRF GSC3f LPx chipset by adding carefully selected key components including
TCXO, LNA and Flash. This ensures frequency stability, improved sensitivity at low level signals of better than –159 dBm, lower
power consumption and a faster TTFF (Time To First Fix). The GSC3e LPx chip integrates both baseband and RF sections,
thereby reducing power consumption.

2.3 Major components of the Jupiter 3-30
lnaswitch:
this switch controls the LNA during low power modes.
Biast:
this provides the voltage to an external active antenna.
BandpassSaWfilter(1.575GHz):
this filters the GPS signal removing unwanted signals caused by external influences that
would corrupt the operation of the receiver. The filtered signal is fed to the RF input of GSC3 chipset for further processing.
The filter has a bandwidth of 2 MHz.
tCXo(temperatureCompensatedCrystaloscillator):
this highly stable 16.369 MHz oscillator controls the down conversion
process for the RFIC block.
regulator:
this dual low-noise regulator provides two outputs of 2.85 V power to the RF section and the digital IO section of
the GSC3 chip.
mainpower:
primary supply voltage range is 3.0–3.6 V.
Brownoutdetector:
the precision voltage detector chip senses the input voltage and resets the module in case of any drop in
the voltage. This detector chip also serves the function of power-on-reset.
or-ingcircuit:
this circuit distributes the RTC/SRAM voltage from either the main voltage supply or the back-up voltage
input in order for the RTC/SRAM elements to work in low power and continuous modes. However a back-up voltage must be
connected if the device is to be shut down and expected to perform Hot and Warm starts.
Vdd_rtCregulator:
supplies a regulated voltage for the RTC/SRAM cell within the GSC3 chip.
Batterypower:
the back-up battery supply feeds the VDD_RTC regulator through the OR-ing circuit, and provides the power
to the battery-backed SRAM and the RTC section of the GSC3.

Pr
lna(lownoiseamplifier):
this amplifies the GPS signal and provides enough gain for the receiver to use a passive antenna.
A very low noise design is used to provide maximum sensitivity.

GSC3elPxchip:
this single chip GPS device includes an integrated Baseband and RF section.
flash:
the 4 Megabit Flash memory stores software and also some long term data.
rtC(realtimeClock)crystal:
the 32 kHz crystal operates in conjunction with the RTC inside the baseband block, and
provides an accurate clock function when main power has been removed, if the battery backup is connected.
