2.2. POLARX5TR DESIGN
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.
In case the receiver is only powered through PoE, pressing the power button resets the
receiver. After a few seconds, the receiver will restart.
In case the receiver is powered through the PWR connector or through both PWR and PoE,
pressing the power button turns the receiver off. 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 offbefore the power outage, it will restart when power is restored.
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 PolaRx5TR can log data to an external memory device.

3 Getting started with the PolaRx5TR
This section details how to power-up, connect to and communicate with the PolaRx5TR. The
PolaRx5TR has an on-board web interface which you can connect to in three ways: Ethernet,
USB or WiFi. The PolaRx5TR 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 PolaRx5TR
You can power the PolaRx5TR 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 PolaRx5TR 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 PolaRx5TR has a TNC connector labelled MAIN to connect a GNSS
antenna. Connect an antenna to the PolaRx5TR 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 PolaRx5TR will start to track satellites and the tracking LED will
12

3.3. CONNECTING TO THE POLARX5TR 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 E.
3.3 Connecting to the PolaRx5TR 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 PolaRx5TR 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.
13

3.3. CONNECTING TO THE POLARX5TR 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 PolaRx5TR functions as network adapter and the DHCP server
running on the receiver will always assign the PolaRx5TR the IP address 192.168.3.1.
To connect to the PolaRx5TR, 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 PolaRx5TR over USB using the IP
address 192.168.3.1 on any web browser
14

3.3. CONNECTING TO THE POLARX5TR 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 PolaRx5TR 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 PolaRx5TR identifies itself as a
wireless access point named ’PolaRx5TR-serial number’. The serial number of the PolaRx5TR
can be found on an identification sticker on the receiver housing. Select and connect to the
PolaRx5TR as shown in Figure 3-7.
Figure 3-7: Select the PolaRx5TR from the list of detected wireless signals and
connect

3.3. CONNECTING TO THE POLARX5TR 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 PolaRx5TR 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 ‘PolaRx5TR-xxxxxxx’, where xxxxxxx are the 7 digits of
the serial number of the GNSS Receiver Board (GRB) inside the PolaRx5TR. 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://PolaRx5TR-xxxxxxx.
Figure 3-10 shows a screenshot of an Ethernet connection to a PolaRx5 receiver with serial
number 3013369 using ‘http://polarx5-3013369/’.

4 The PolaRx5TR for time and frequency
transfer
This chapter details the configuration of the PolaRx5TR receiver and the RxControl tool for
timing applications and CGGTTS generation.
4.1 Setup for timing applications
In time and frequency transfer applications, the receiver is fed with a 10 MHz reference and
a PPS signal originating from an external clock. The 10 MHz reference signal is connected
to the REF IN connector, and the PPS signal is connected to the PPS IN connector of the
PolaRx5TR. This has the effect of aligning the receiver time with the time of the external
clock, bypassing the receiver’s internal clock.
It is important that the PPS input signal and the 10 MHz REF IN reference are generated from
the same external clock and that the PPS input signal be roughly synchronized to UTC (offset
with UTC should be smaller than 0.5 milliseconds). It is also necessary that the REF IN and
PPS IN signals are present from the start-up of the receiver. Plugging in a PPS input signal
when the receiver is already operating will lead to erroneous measurements.
A typical setup is shown in Figure 4-1. The various delays involved in time-transfer
applications are also indicated in the figure.
Figure 4-1: Typical setup for time-transfer applications showing relevant delays
18

4.2. CALIBRATION OF THE DELAY FROM PPS IN TO THE INTERNAL TIME REFERENCE
4.2 Calibration of the delay from PPS IN to the
internal time reference
The receiver synchronises its own internal time reference (i.e. its measurement latching)
with the low-to-high transitions of the reference time signal at the PPS IN connector. This
synchronisation occurs with some small delay, often referred to as ‘XO’in the literature (see
Figure 4-1). In the PolaRx5TR, XOcan take any value from 24ns to 59ns depending on the
phase relationship between the 10 MHz frequency reference and the PPS input signal at the
REF IN and PPS IN connectors respectively. XOremains constant when the receiver is reset or
power-cycled, but changes when the cables feeding the REF IN and/or the PPS IN connectors
are changed.
XOcan either be left uncompensated, or can be measured and compensated for by the
receiver itself. For legacy reasons, the compensation is disabled by default. In new
installations that have not been calibrated yet, it is easier to enable XOcompensation. Both
options are described below.
4.2.1 XOuncompensated
This is the default behaviour. To verify that the XOcompensation is disabled, check that ‘off’
has been selected in the ‘PPS In Parameters’ field on the Timing>PPS window of the Web
Interface as shown in Figure 4-2.
Figure 4-2: Configuration to disable automatic PPS IN internal delay
compensation (PPS IN Parameters) and to bring the measurement latching strobe
to the PPS OUT connector (PPS OUT Parameters)
The XOdelay is the delay from the PPS IN connector to the actual measurement latching (see
Figure 4-1). The measurement latching is an internal signal, but it can be brought to the PPS
OUT connector so that it can be monitored externally. This is done by selecting ‘RxClock’in
the ‘PPS OUT Parameters’ field as shown in Figure 4-2. In this configuration, the PPS OUT
materializes the internal receiver time reference.
An example of a setup which can be used to manually determine the delay between the PPS
IN and the internal time reference (XO) is shown in Figure 4-3. For this calibration, it is not
necessary to connect an antenna to the receiver. For the most straightforward interpretation
of the results, cables C1 and C2 should have the same length.
19

4.2. CALIBRATION OF THE DELAY FROM PPS IN TO THE INTERNAL TIME REFERENCE
Figure 4-3: Manual calibration of the PPS IN to internal reference delay
XOis the time difference between the leading edges of the pulses on the Input 1 and Input 2
ports of the oscilloscope. The oscilloscope trigger level should be set to 1V.
The measured XOshould be a value between 24ns and 59ns. The value depends on the
relative length of the REF IN and PPS IN cables, as shown in Figure 4-4.
Figure 4-4: Variation of XOas a function of the relative cable length
It is recommended to avoid operating the receiver in the gray zones of Figure 4-4. Therefore,
if XOis found to be lower than 26ns or larger than 57ns, it is recommended to change
the length of the REF IN or of the PPS IN cable. A change of 1 meter in the cable length
corresponds to a change of XOby about 5ns. Adding length to the REF IN cable increases the
XOvalue. Adding length to the PPS IN cable decreases the XOvalue.
4.2.2 Auto-Calibration and compensation of XO
The PolaRx5TR incorporates a circuit to calibrate the PPS IN internal delay and to compensate
for it. Enabling XOcompensation can be done on the Timing>PPS window of the Web
Interface, as shown in Figure 4-5.
