CHAPTER 3. CONFIGURING THE ASTERX SB PRO DIRECT
3.3 How to configure the AsteRx SB ProDirect
for Attitude
With two antennas connected to the AsteRx SB ProDirect, the receiver can calculate Heading
and either Pitch or Roll. This section details how to configure the AsteRx SB ProDirect in a
two-antenna setup.
Step 1: Connect a second antenna
Connect a second antenna to the front panel connector labelled AUX ANT as indicated in
Figure 3-11.
Figure 3-11: Auxiliary antenna connector on front panel
Step 2: Configure attitude settings
The attitude settings of the AsteRx SB ProDirect can be configured in the GNSS, Attitude
window as shown in Figure 3-12.
15
CHAPTER 3. CONFIGURING THE ASTERX SB PRO DIRECT
Figure 3-12: GNSS Attitude window when two antennas are connected
GNSS Attitude field
The recommended settings for a Heading setup are MultiAntenna mode with attitude
calculated using Fixed ambiguities as shown. These setting are configured by default.
16
CHAPTER 3. CONFIGURING THE ASTERX SB PRO DIRECT
Antenna Location and Antenna Offset
The AsteRx SB ProDirect assumes that the main and auxiliary antennas are placed along the
longitudinal axis of the vehicle with the auxiliary in front of the main antenna. If the antennas
cannot be placed in such a configuration, the reported heading and pitch may be biased. The
default settings in the Antenna Offset and Antenna Location fields shown in Figure 3-13
can be altered to compensate for these biases.
In many cases the antenna baseline will not align perfectly with the vehicle’s longitudinal axis
or its perpendicular and in these circumstances the provided attitude offset value can also be
used to compensate for small angular deviations. Note that, in order to ensure the integrity
of the solution, offsets greater than 5 degrees from the longitudinal axis or its perpendicular
are not recommended.
An increase in angle between the antenna baseline and the vehicle’s longitudinal axis in the
clockwise direction corresponds to a positive change in the value of the heading offset To
better explain this, a few examples of possible setups are given below in Figure 3-13.
Figure 3-13: Examples of a number of antenna setups and the corresponding
heading offsets. a.) The default setup for which the angle between the antenna
baseline and the longitudinal axis is 0 and no heading offset needs to be set. b.)
a slight deviation (5 degrees) from the longitudinal axis in the clockwise direction
is reflected by a positive increase in the heading offset. c.) An alternative antenna
configuration where the antennas are placed perpendicular to the longitudinal
axis. d.) An alternative antenna configuration where the antennas are placed
perpendicular to the longitudinal axis with a small deviation.
The examples above all relate to a heading offset but the antenna orientation can also
be characterized by a vertical offset. Vertical offsets can be compensated for by adjusting
the Pitch offset. This may be necessary in cases where the antenna baseline is not exactly
parallel to the longitudinal axis of the vehicle or in situations where the two antenna ARPs
17
CHAPTER 3. CONFIGURING THE ASTERX SB PRO DIRECT
may not be exactly at the same height in the vehicle reference frame. Since pitch is defined
as the right-handed rotation about the vehicle Y axis, a situation where the main antenna is
mounted lower than the aux antenna (assuming the default antenna setup) will result in a
positive pitch a shown in Figure 3-14.
Figure 3-14: Visual representation of the effect of vertical offset between the two
antennas on the Pitch offset. Assuming the default antenna configuration, the aux
antenna being mounted higher will result in a positive value for the pitch.
18
CHAPTER 3. CONFIGURING THE ASTERX SB PRO DIRECT
Step 3: Attitude information in SBF and NMEA data
Details on how to output SBF and NMEA data can be found in Section 4.1.
SBF
Attitude information is contained in the SBF blocks AuxAntPositions, AttEuler, AttCovEuler and
EndOfAtt. These blocks are selected automatically when checking the ‘Attitude’ box when
configuring SBF output via the NMEA/SBF Out window as Figure 3-15 shows.
Figure 3-15: SBF blocks containing attitude information
NMEA
You can output the attitude information from the AsteRx SB ProDirect in NMEA format by
selecting the standard NMEA HDT sentence or the Septentrio proprietary HRP sentence as
shown in Figure 3-16.
Figure 3-16: NMEA sentences containing attitude information
19
CHAPTER 4. COMMON RECEIVER OPERATIONS
4 Common Receiver Operations
4.1 How to configure SBF and NMEA output
The AsteRx SB ProDirect can output position and GNSS data in both standard NMEA format
and Septentrio’s proprietary compact binary format SBF. The following sections detail how
to configure connections to other devices in order to send data.
SBF and NMEA can also be logged on the internal 16 GB disk of the AsteRx SB ProDirect.
Section 4.2.1 and 4.3 detail how to log data on the receiver and how to download data logged
on the receiver.
4.1.1 Output over a serial COM connection
The AsteRx SB ProDirect can be connected via a serial COM cable to an RS-232 compatible
secondary device.
Step 1: Configure the serial COM port
The COM port of the AsteRx SB ProDirect should be configured with the same baud rate
and flow control setting of the coupled device. These settings can be configured via the
Communication/Serial Port tab as shown in Figure 4-1. In this example, COM3 is set with a
speed of 19200 baud.
Figure 4-1: Configure the baud rate and flow control of the AsteRx SB ProDirect
20
CHAPTER 4. COMMON RECEIVER OPERATIONS
Step 2: Configure data output
NMEA
In the NMEA/SBF Out tab, clicking on New NMEA Stream will guide you through the steps
needed to configure NMEA output as shown in Figures 4-2 and 4-3.

21
CHAPTER 4. COMMON RECEIVER OPERATIONS
SBF
By clicking New SBF stream in the NMEA/SBF Out window, a second output stream can be
configured. In the example shown in Figures 4-4 and 4-5 the PVTCartesian SBF data block
will be output over COM1 once per second.
Figure 4-4: Selecting to output SBF data on COM1
Figure 4-5: Selecting to output the PVTCartesian SBF block every second
22
CHAPTER 4. COMMON RECEIVER OPERATIONS
Step 3: Verifying the configuration
Having configured the data output and clicked on Ok, the NMEA/SBF Out page will now
display a summary of all data output as shown in Figure 4-6.
Figure 4-6: Summary of all configured data output streams
Figure 4-7 shows the actual data output. NMEA is in ASCII and is thus readable unlike SBF
which is formatted in binary. In this example, the serial COM was connected to a PC via a
USB adapter which maps the serial connection to a virtual COM9 of the PC.
Figure 4-7:
Example showing output of NMEA GGA (left panel) and SBF
PVTCartesian (right panel) data
23
CHAPTER 4. COMMON RECEIVER OPERATIONS
4.1.2 Output over Ethernet
SBF and NMEA data can be sent over an Ethernet connection from the AsteRx SB ProDirect.
Step 1: Configure an IP connection on the AsteRx SB ProDirect
The Ethernet port settings can be configured by selecting IP Ports from the Communication
menu. In the example shown in Figure 4-8, port 600 has been configured as connection IPS1
in TCP2Way mode so data can be received as well as transmitted over the connection. When
choosing a port number, avoid conflicts with other applications such as 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).
Note that a new IP port can also be configured by followings the sequence of settings for
NMEA output described in Step 2.
Figure 4-8: Configuring the TCP/IP server port setting for data output
24
CHAPTER 4. COMMON RECEIVER OPERATIONS
Step 2: Configure output of NMEA messages
In the NMEA/SBF Out window, click on New NMEA stream and follow the sequence of
windows to configure the data you want to output. In the example shown in Figure 4-9, the
NMEA GGA message will be output every second. Ensure that the previously configured IPS1
port is selected for output as highlighted.
Figure 4-9: Outputting NMEA GGA over the configured IPS1 connection
Similar steps can be followed to output SBF messages.
25
CHAPTER 4. COMMON RECEIVER OPERATIONS
Step 3: Configure Data Link to listen for NMEA output
The screenshots in Figure 4-10 show how the Septentrio GUI tool Data Link can be configured
to listen for the AsteRx SB ProDirect GGA output.
Click on the TCP/IP Client button to configure the connection. In the highlighted fields insert
the IP address or hostname of the receiver and the port number configured in Step 1. Click
on Connect.

CHAPTER 4. COMMON RECEIVER OPERATIONS
4.2 How to log data
The AsteRx SB ProDirect has 16 GB of memory for internal data logging.
4.2.1 Internal logging
Step 1: Defining the Disk Full action
When setting up a logging session for the first time, it is a good idea to define what you would
like to happen when the internal memory is full. This can be configured in the Advanced tab
of the main page of the Logging menu as shown in Figure 4-12. There are two options, either
the receiver stops logging when the memory is full or it continues logging by making space
for new files by deleting the oldest files. The default setting is ’Stop logging in all sessions’.
Figure 4-12: Selecting what you wish to happen when the internal 16 GB memory
is full
28
CHAPTER 4. COMMON RECEIVER OPERATIONS
Step 2: Configuring a logging session
To define a new logging session, press New NMEA Stream or New SBF Stream as shown in
Figure 4-13.
Figure 4-13: Defining a new logging session
You can then follow the sequence of steps shown in Figure 4-14, selecting the various
configuration settings for the logging session. In the Edit SBF Stream window, the messages
required for RINEX generation have been selected as well as those useful for the Support
department for diagnosing problems. SBF messages can also be selected individually. In
the SBF Logging Parameters field you can select the naming convention. The IGS options
names files according to IGS convention but files can also be freely named using either
Filename or Incremental options. After you have finished configuring the log session, do
not forget to enable logging and press Ok.

A.4 MAIN ANT / AUX ANT (TNC)
Connect an active GNSS antenna to these connectors. The gain at the connectors (antenna
gain minus cable losses) must be in the range 15 to 50dB.
By default, the receiver provides a 3.3V DC supply on both the MAIN and AUX connectors
to feed the antennas. The supplied antenna voltage can be changed to 5V DC with the
command setAntennaVoltage. The maximum supported current is 200mA.
Never inject a DC voltage into the MAIN or AUX connectors as it may damage the receiver.
When using a splitter to distribute the antenna signal to several receivers, make sure that no
more than one output of the splitter passes DC. Use DC-blocks otherwise.
