3. When connecting power to the SMART-V1 or SMART-V1G,
it is recommended that you use a battery source. In this
case, it is important that you tie together the bare wires
tagged as GND2 (brown) and GND (black) to the battery’s
negative terminal. Tie the bare wires tagged as PWR (red)
and PWR2 (orange) to the battery’s positive terminal.

DETERMINING WHEN THE POSITION IS VALID
LOGGING DATA
ENABLING SBAS POSITIONING
ENABLING L-BAND POSITIONING
When the receiver has a valid position, the Solution Status field
in CDU’s Position window shows Computed.
An extensive collection of logs has been created to capture the
data your SMART-V1/V1G receives and processes. These logs
can be directed to a SMART-V1/V1G port (COM1, COM2 or
USB) and can be automatically generated when new or changed
data becomes available or at regular intervals. The available
logs are listed in the OEMV Family Quick Reference Guide.
SMART-V1/V1G models are also capable of SBAS positioning.
This positioning mode is enabled using the SBASCONTROL
command. The following commands are typically used to enable
WAAS (North America) and EGNOS (Europe) systems:
L-Band equipped receivers allow you to achieve sub-meter
accuracy. To use this positioning mode, you must enable L-band
tracking to the Canada-Wide Differential GPS (CDGPS) or
OmniSTAR signal. A subscription to OmniSTAR is required to
have your receiver’s serial number ready). The CDGPS signal is
free and available without subscription over North America (visit
SBASCONTROL ENABLE WAAS
SBASCONTROL ENABLE EGNOS
ENTERING COMMANDS
To log data, use the LOGcommand. For example, to log the
pseudorange position to COM 2 every 30 seconds, enter the
following:
The SMART-V1/V1G uses a comprehensive command
interface. Commands can be sent to the receiver using the
Console window in CDU, which is opened from the View menu.
Enter commands in the text box at the bottom of the Console
window.
Once enabled, the Position Type field shown in CDU’s Position
window should change from Single to WAAS and you may see
SBAS satellites in the Constellation window.
The ASSIGNLBAND command allows you to set OmniSTAR or
CDGPS base station communication parameters and to start
tracking L-Band satellites. It should include a relevant frequency
and data rate. The frequency assignment can be made in Hz or
KHz. For example:
LOG COM2 PSRPOS ONTIME 30
Logs can be generated in one of three formats: ASCII,
Abbreviated ASCII, or Binary. Refer to the OEMV Family
Firmware Reference Manual (OM-20000094) for information on
the LOGcommand, specifying the output format, and the
detailed contents of each log.
Hz: assignlband omnistar 1536782000 1200
KHz: assignlband omnistar 1536782 1200
The following information is important when entering commands:
A value entered in Hz is rounded to the nearest 500 Hz.
If you prefer, CDU provides a graphical interface for configuring
data logging. Select Logging Control Window from the Tools
menu. In the Logging Control window, you can select which logs
to capture and choose to which ports to send the data. In
addition, you can specify a file in which to save the data.
•
Commands can be entered in three formats:
To confirm you are tracking an L-Band signal, log the L-Band
status information by entering: log lbandstat. For example,
if you are receiving CDGPS, the fifth field after the header
should be 00c2:

Binary (log bestposb).
lbandstata com1 0 43.5 finesteering 1295
149951.671 00000000 976f 34461;
Abbreviated ASCII is the best format to use when you
wish to work with the receiver directly. For data
collection, use ASCII or Binary.

Press Enter to send the command string to the receiver.
To specify the correction source, use the PSRDIFFSOURCE
command as shown in the examples below:
The commands are not case sensitive.
PSRDIFFSOURCE OMNISSTAR

or,
The OEMV Family Quick Reference Guide provided with the
receiver lists the available commands and the parameters they
use for the Abbreviated ASCII format.
otherwise it is left at the default AUTOMATIC.

REAL-TIME KINEMATIC (RTK) POSITIONING
USING THE CAN BUS
QUESTIONS OR COMMENTS
Corrections can be transmitted from a base station to a rover
station to improve position accuracy. The base station is the
GNSS receiver which is acting as the stationary reference. It has
a known position and transmits correction messages to the rover
station. The rover station is the GNSS receiver which does not
know its exact position and can receive correction messages
from a base station to calculate differential GNSS positions.
A CAN Bus is a serial bus that provides services for processes,
data and network management. There is a CAN Bus capable
model of the SMART-V1 with its own multi-cable. CAN Bus
functionality is controlled through NovAtel’s optional API
software available through Customer Service. The API header
file (*.h), in the API folder after installation, includes
documentation on using the CAN Bus.
If you have any questions or comments regarding your
SMART-V1 or SMART-V1G please contact NovAtel using
one of these methods:

In most cases you need to provide a data link between the base
station and rover station (two NovAtel receivers) in order to
receive corrections. SBAS and L-Band corrections can be
accomplished with one receiver and are exceptions to the base/
rover concept. Generally a link capable of data throughput at a
rate of 9600 bits per second, and less than 4.0 s latency, is
recommended.
POST PROCESSING

Post-mission data processing refers to when the GPS data
collected by the receiver is processed after the entire data-
collection session is complete.

RT-20, with AdVance RTK, is a real-time kinematic software
product developed by NovAtel. Optimal RTK performance is
achieved when both the base and rovers are NovAtel products.
However, AdVance RTK will operate with equipment from other
manufacturers when using RTCM messaging.
OEMV-based output is compatible with post-processing
software from the Waypoint Products Group, NovAtel Inc. For
details, visit our website at:
Once your base and rover are set up, you can configure them for
RTCM, RTCMV3 or CMR corrections. An RTCM example
follows (replace the latitude, longitude and height coordinates
shown in the FIX command line with those of your base):
RT-20 is supported by GPS-only and GPS+GLONASS models.
Also, RT-20 with GPS+GLONASS provides faster convergence.
