CHAPTER 2. ASTERX SB I 3 OVERV I EW
The power consumption of the AsteRx SBi3 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 Wideband I nterference mitigation (WB I ) with the
setWBIMitigation command.
The following table shows the nominal power consumption measured when 12 VDC is
supplied to the PWR connector:
Configuration

GPS + GLONASS L1 + L2, RTK, Dual antenna (externally
powered), 10Hz internal logging active

2.3 Powering the receiver
The receiver can be powered through either:
• The PWR connector (5 to 36 VDC)
• The Ethernet connector (Power over Ethernet - PoE, 37-57 VDC). (Please note that only
mode A, as speci
fi ed in the 802.3af standard, is supported.)
