1Introduction
The C101-D9S board is a convenient tool that allows customers to become familiar with the u-blox
NEO-D9S L-band correction data receiver. The board provides facilities for evaluating the product and
demonstrating its key features.
NEO-D9S is a satellite data receiver for L-band correction broadcasts and can be configured for use
with a variety of correction services. Using such correction services enables high precision navigation
globally in multiple regions, as well as coverage across continents.
The C101-D9S application board offers:
•NEO-D9S module for use as L-band correction data receiver
•USB connection for communication and power supply
•L-band antenna connection for receiving the satellite data stream
•Arduino shield connection
1.1 Package contents
The delivered package contains:
•C101-D9S board
•L-band antenna
•Antenna ground plane (12 cm circular)
•USB interconnect cable
•Jumper connectors
Prior to using the board, it is useful to download the appropriate evaluation software and keep handy
the documents listed in the Related documents section.

2.2 Jumpers
The board is delivered with the following default jumpers:
•J6: This jumper provides 3.3 V power supply to an external active antenna plugged to the SMA RF
connector. The current limit circuit is also enabled up to 60 mA.
•J8: This jumper switches the communication from the UART2 of the NEO-D9S to the J2 or J3
connector of the Arduino shield (refer to Appendix D for further details).

3C101-D9S standalone operation
This section provides some quicksteps to enable NEO-D9S standalone operation, and connecting via
u-center (see u-center user guide [3]).
•Connect the supplied L-band antenna to the RF SMA connector. Ensure good visibility of the GEO
communication satellites.
•Connect the USB to a Windows PC, this will power the board. The FTDI and USB drivers will be
installed automatically from Windows Update when the user connects the board for the first time.
•The power LED will turn on in blue color.
•Start the Device Manager utility from Windows. Two new ports will be visible under the Ports tab:
the USB Serial Device is the Native USB port and the USB Serial Port is the FTDI USB bridge port,
as shown in Figure 4.
Figure 4: Windows Device Manager Ports identifications
Figure 5: FTDI USB bridge and USB ports properties
•Start u-center and connect to one of the COM ports. If you are using the FTDI USB bridge, make
sure the baud rate in u-center is set to 9600.
•Poll UBX-MON-VER message and check the content as shown in Figure 6.

Figure 6: UBX-MON-VER message
NEO-D9S needs to be properly configured to receive the L-band signal correction data. See Appendix
B for the default NEO-D9S L-band configuration, which can be adapted for other services.
The messages UBX-MON-PMP and UBX-RXM-PMP (see Figure 7 and Figure 8) can be polled or
enabled to check respectively the reception of the signal and the decoded correction data.

BNEO-D9S L-band configurations
Correction services from several providers are available via the L-band communication satellites. The
service provider will have several correction service specific configurations that need to be configured
before the receiver can provide the relevant service provider data such as:
•Service provider service ID
•Service provider frequency based on geographical location
•Service provider data rate
This means that the frequency allocation for a particular service provider could change. Service
providers do provide information on any frequency changes when required.
The NEO-D9S default L-band configuration keys are listed below:
•CFG-PMP-CENTER_FREQUENCY = 1539812500 Hz
•CFG-PMP-SEARCH_WINDOW = 2200 Hz
•CFG-PMP-USE_SERVICE_ID = 1 (true)
•CFG-PMP-SERVICE_ID = 50821
•CFG-PMP-DATA_RATE = 2400 (B2400) bps
•CFG-PMP-USE_DESCRAMBLER = 1 (true)
•CFG-PMP-DESCRAMBLER_INIT = 23560
•CFG-PMP-USE_PRESCRAMBLING = 0 (false)
•CFG-PMP-UNIQUE_WORD = 16238547128276412563
The NEO-D9S correction data receiver is fully compliant with the u-blox configuration concept. The
messages UBX-CFG-VALSET, UBX-CFG-VALGET and UBX-CFG-VALDEL are used to configure the
above keys. See the NEO-D9S Integration manual [1] for further details.
