2 PolaRx5 overview
2.1 Hardware Specifications
2.1.1 Power Consumption
The power consumption of the PolaRx5 depends on its con
fi
guration. The following settings
directly in
fl
uence the amount of power consumed:
•
The number of enabled GNSS frequency bands. For example, a receiver con
fi
gured
to track signals only in the L1 and L2 bands will consume less than a receiver
con
fi
gured to track in the L1, L2 and L5 bands. Use the
setSignalTracking
command
to enable/disable signals. Note that a given frequency band is disabled only when all
GNSS signals in that band are disabled.
•
The activation of the Ethernet interface.
I
n power-critical applications, it is
recommended to not use Ethernet and to turn o
ff
the associated hardware. This can
be done with the
setEthernetMode
command.
•
The activation of the WiFi interface. Use the
setWiFiMode
command or press the WiFi
button to turn o
ff
or on the WiFi module.
•
The REF OUT frequency reference output.
I
n power-critical applications, REF OUT can
be turned o
ff
with the
setREFOUTMode
command.
•
The
activation
of
the
Wideband
I
nterference
mitigation
(WB
I
)
with
the
setWBIMitigation
command.
•
Enabling the L-band demodulator using the
setLBandSelectMode
command.
The following table shows the nominal power consumption measured when 12 VDC is
supplied to the PWR connector:
