2 PolaRx5S overview
2.1 Hardware Specifications
2.1.1 Power Consumption
The power consumption of the PolaRx5S depends on its configuration. The following settings
directly influence the amount of power consumed:
•The number of enabled GNSS frequency bands. For example, a receiver configured
to track signals only in the L1 and L2 bands will consume less than a receiver
configured 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.
•Activation of the Ethernet interface: in power-critical applications, it is recommended
to not use Ethernet and to turn offthe associated hardware. This can be done with the
setEthernetMode command.
•Activation of the WiFi interface: use the setWiFiMode command or press the WiFi
button to turn the WiFi module offor on.
•The REF OUT frequency reference output: in power-critical applications, REF OUT can
be turned offwith the setREFOUTMode command.
The following table shows the nominal power consumption measured when 12 VDC is
supplied to the PWR connector:
Configuration Power
Consumption†
GPS + GLONASS L1, tracking and PVT 3.5W
GPS + GLONASS L1/L2, tracking and PVT 3.6W
GPS L1/L2/L5, GLO L1/L2, GAL E1/E5a, SBAS L1/L5, BDS B1/B2 3.7W
All constellations and all signals
(enabling GAL E6 and/or BDS B3 increases the power by 650mW) 4.5W
Enabling Ethernet (setEthernetMode command) +650mW
Enabling WiFi (setWiFiMode command) +450mW
Enabling REFOUT (setREFOUTMode command) +30mW
Enabling wide-band interference mitigation (setWBIMitigation command) +160mW
Enabling internal logging at 1 Hz/10 Hz +50mW/+70mW
Stand-by mode†1.6W
∗Note that initial power consumption can be 3W higher than the values listed due to
warming up of the internal OCXO.
†Stand-by mode is described in Section 2.2.4
The power consumption in standby mode is 0.22W

Figure 2-2 shows the layout of the rear-panel connectors on the PolaRx5S. More information
on these connectors can be found in Appendix B.
Figure 2-2: PolaRx5S rear-panel layout
2.2.3 Powering the Receiver
The receiver can be powered through either:
•The PWR connector (9-30 VDC)
•The Ethernet connector (Power over Ethernet - PoE, 37-57 VDC). Please note that only
mode A, as specified in the 802.3af standard, is supported.
If power is provided through both the Ethernet and the PWR connectors, Ethernet power
takes precedence. This allows the connection of a back-up battery to the ODU PWR
connector. The battery will only be used in case of an outage of the power over Ethernet.
The current power source (PWR or Ethernet connector), and the voltage at the PWR
connector are reported in the PowerStatus SBF bock.
2.2.4 Power Button
When power is initially applied to the PWR or Ethernet connector, or after a power outage,
the receiver always starts up without the need to press the power button.
Pressing the power button when the receiver is turned on will send the receiver into stand-by
mode. Pressing the button again switches the receiver back on.
In all cases, the state of the power button is not retained across a power outage. If the
receiver was in stand-by mode before the power outage, it will restart when power is
restored.
11

2.2. POLARX5S DESIGN
2.2.5 WiFi Button
The WiFi button toggles the WiFi modem on and off.
When the receiver starts up, WiFi is enabled or disabled according to the settings of the
setWiFiMode command stored in the boot configuration file. When the receiver is operating,
pressing the WiFi button turns WiFi on and offin turn. The red WiFi LED next to the WiFi
button lights when WiFi is enabled.
2.2.6 Internal memory
The PolaRx5 has a 16 GB Memory for internal data logging. Data can be logged in SBF, RINEX,
BINEX, NMEA or RTCM-MSM format and may be retrieved via the âĂŸLoggingâĂŹmenu of the
web interface.
2.2.7 External memory
The PolaRx5S can log data to an external memory device.

3 Getting started with the PolaRx5S
This section details how to power-up, connect to and communicate with the PolaRx5S. The
PolaRx5S has an on-board web interface which you can connect to in three ways: Ethernet,
USB or WiFi. The PolaRx5S is fully configurable using the web interface. Please note that
older versions of certain browsers may not properly display the web interface.
3.1 Powering the PolaRx5S
You can power the PolaRx5S by connecting the power adapter that is supplied as standard
to the front-panel power socket as indicated in Figure 3-1. The receiver will start up
automatically without pressing the power button.
Figure 3-1: Front-panel power socket
The PolaRx5S can also be powered over Ethernet (PoE) as described in Section 2.2.3 or by
supplying 9 to 30 V via PIN 1 of the open-ended power cable (CBLe_PWR_OE) as detailed in
Appendix A.8.
3.2 Connecting an antenna
The rear panel of the PolaRx5S has a TNC connector labelled MAIN to connect a GNSS
antenna. Connect an antenna to the PolaRx5S using an antenna cable as shown in Figure 3-2.
The connector can provide 5V DC and up to 200 mA to power an antenna (see Appendix B.1
for more information).
Figure 3-2: Rear-panel antenna connector
Before connecting an antenna, the orange front-panel tracking LED will be blinking fast
indicating that the receiver is searching for satellites. After connecting an antenna that has
a clear view of the sky, the PolaRx5S will start to track satellites and the tracking LED will
13

3.3. CONNECTING TO THE POLARX5S VIA THE WEB INTERFACE
start to blink more slowly. The number of blinks between pauses indicates the number of
satellites being tracked as described in Appendix D.
3.3 Connecting to the PolaRx5S via the Web
Interface
You can connect to the receiver on any device that supports a web browser using the
receiver’s on-board Web Interface. The connection can be made over USB, Ethernet or WiFi.
The following sections describe each of the connection methods.
3.3.1 Using the USB cable
Connect the USB cable (CBLe_USB) to the socket labelled COM3-4/USB on the front panel of
the PolaRx5S as indicated in Figure 3-3.
Figure 3-3: Connecting to the front-panel USB socket
The first time that the USB cable is connected to your pc, you may be prompted to allow
installation of drivers which can take several minutes. When the drivers have been installed,
it is recommended to unplug then re-plug in the USB cable on your device to fully activate
the drivers.
If the USB drivers do not install automatically, they can be installed manually by double
clicking on the executable installer file found in the folder ‘driver’as shown in Figure 3-4.
14

3.3. CONNECTING TO THE POLARX5S VIA THE WEB INTERFACE
Figure 3-4: Manually installing the USB drivers
Again, when the drivers have been installed, it is recommended to unplug then re-plug in the
USB cable on your device to fully activate the drivers.
The USB connection on the PolaRx5S functions as network adapter and the DHCP server
running on the receiver will always assign the PolaRx5S the IP address 192.168.3.1.
To connect to the PolaRx5S, you can then simply open a web browser using the IP address
192.168.3.1 as shown in Figure 3-5.
Figure 3-5: Connect to the Web Interface of the PolaRx5S over USB using the IP
address 192.168.3.1 on any web browser

3.3. CONNECTING TO THE POLARX5S VIA THE WEB INTERFACE
3.3.2 Over WiFi
The Web Interface can also be accessed over a WiFi connection. You can turn on the WiFi
modem of the PolaRx5S by pressing firmly on the WiFi button as shown in Figure 3-6.
Figure 3-6: Press firmly on the front-panel WiFi button to turn on the WiFi modem.
When active, the red WiFi led will be lit.
On your PC or tablet, search for visible WiFi signals: the PolaRx5S identifies itself as a
wireless access point named ’PolaRx5S-serial number’. The serial number of the PolaRx5S
can be found on an identification sticker on the receiver housing. Select and connect to the
PolaRx5S as shown in Figure 3-7.
Figure 3-7: Select the PolaRx5S from the list of detected wireless signals and

3.3. CONNECTING TO THE POLARX5S VIA THE WEB INTERFACE
3.3.3 Using the Ethernet cable
Connect the Ethernet cable (CBLe_ETH_MS) to the socket labelled ETH on the front panel of
the PolaRx5S as shown in Figure 3-9.
Figure 3-9: Connecting to the front-panel Ethernet socket
For the most straightforward setup, the RJ45 socket of the Ethernet cable should be
connected to a network running a DHCP server. The IP address assigned to the receiver
will be associated with the hostname ‘PolaRx5S-xxxxxxx’, where xxxxxxx are the 7 digits of
the serial number of the GNSS Receiver Board (GRB) inside the PolaRx5S. This number can
also be found on an identification sticker on the receiver housing. You can then make a
connection to the receiver using the web address http://PolaRx5S-xxxxxxx.
Figure 3-10 shows a screenshot of an Ethernet connection to a PolaRx5 receiver with serial
number 3013369 using ‘http://polarx5-3013369/’.

4 Reference station operation
4.1 How to configure the PolaRx5S as an RTK
base station
The PolaRx5S can be configured to work as a base station and provide differential correction
data to one or more rover receivers. The steps below describe how to configure the position
of the reference station and output differential corrections over an Ethernet connection.
Connecting to the PolaRx5S over Ethernet is described in Section 3.3.3.
Step 1: Configuring the PolaRx5S base station position
Set the position as static
To work as a base station, the position of the PolaRx5S should be set to static. If not, the
PolaRx5S will still work as a base station however the position of the rover may show more
variation. The ‘Static’position mode can be selected in the ‘Position’window of the ‘Station’
menu as shown in Figure 4-1.
Figure 4-1: Setting the PolaRx5S base station position to static
Set the correct position
An accurate position of the antenna that is connected to the PolaRx5S should also be set. The
default setting of ‘auto’can be used for demonstrations however, for most other purposes,
a properly surveyed position is advisable. In the example shown in Figure 4-2, the position
stored under ‘Geodetic1’is used. The antenna position can be entered in either Geodetic or
Cartesian coordinates.
Select the Datum of the antenna position
In the Datum field, you can select the datum to which the antenna coordinates refer.
The selected value is stored in the Datum field of position-related SBF blocks (e.g.
PVTCartesian) and also in any output differential corrections. Please note that the Datum
setting does not apply any datum transformation to the antenna position coordinates.
19

4.1. HOW TO CONFIGURE THE POLARX5S AS AN RTK BASE STATION
Figure 4-2: Setting the static position of the reference station antenna
Click on ‘Ok’to apply the new settings
Step 2: Configure output of correction data over Ethernet
Output of differential corrections can be configured in the Corrections Output window as
Figure 4-3 shows. Click on New RTCM3 output to start the sequence of configuration steps.
RTCMv3 is the most compact and robust differential correction format and it is
recommended to use this format where possible.
Select the Ethernet port you wish to use avoiding the commands port (28784), the webserver
port (80), the FTP port (21) as well as the default NTRIP port (2101) and the NTP port (123).
The example shown in Figure 4-3 uses port 28785.
The messages necessary for RTK and DGNSS are selected by default. A summary of other
RTK messages can be found in the ‘PolaRx5S Reference Guide’.
