automatically open when the CD is inserted, select Run from
the Start menu and then the Browse button to locate
Setup.exe on the CD drive.
Power cable supplied with Deutsch connector
1
and at least a 6 V DC power supply, 750 mA
•
•
A quality GNSS antenna, such as NovAtel’s dual-
frequency GPS-702, or ANT-532-C for airborne/high
speed applications. For FlexPak-V1 L-Band corrections
use the GPS-702L antenna or for GLONASS
applications use the GPS-702GG antenna.
4. Install the PC Utilities by advancing through the steps
provided in the NovAtel GPS PC Utilities setup program.
The FlexPak-V1/V1G/V2 provides a USB connection through its
COM1 or COM2 port. The USB drivers, along with installation
instructions, are available in the USB Drivers directory of the CD
provided. An installation program for NovAtel’s PC Utilities,
including the CDU (Control and Display Unit) user interface, and
the OEMV Software Development Kit, are also on the CD.
An antenna cable with a TNC male connector at the
receiver end, such as NovAtel’s GPS-C016 model
4. Connect the power cable connector to the PWR port. The
threads of the Deutsch connector ratcheting mechanism fit
tightly with that of the PWR port.
SETTING UP YOUR FLEXPAK-V1/V1G/V2
Complete these steps to connect and power your FlexPak.
Each FlexPak receiver has 2 SBAS channels. FlexPak-V1G is a
GLONASS model. There are FlexPak-V1 L-Band and FlexPak-
V2 GLONASS models also available.
1. Mount an antenna on a secure, stable structure with an
unobstructed view of the sky.
2. Using a coaxial cable, connect the antenna to the
port, which is found on the front face of the FlexPak.
BOX CONTENTS
In addition to this Quick Start Guide, the following is provided
with your FlexPak-V1/V1G/V2:
•
•
•
•
•
1 power adapter cable
1 null modem serial cable with a DB-9F (female) end
1 straight through serial cable with a DB-9M (male) end
1 USB serial cable
5. Plug in the adapter and/or connect and turn on the power
supply. If there is an LED provided above the PWR port, the
LED will be red when the FlexPak is properly powered.
1 CD containing:
•
•
•
NovAtel’s PC Utilities’ installation program
Product documentation, including user manuals
The OEMV Software Development Kit
1. If an alternative power source is preferred, the 12V power adapter
can be cut off from the power cable. The exposed wires can then be
tied to a supply capable of at least 5 W. The use of a 3 A slow-blow
fuse is recommended.

LOGGING DATA
ENABLING SBAS POSITIONING
ENABLING L-BAND POSITIONING (FlexPak-V1 only)
An extensive collection of logs has been created to capture the
data your FlexPak receives and processes. These logs can be
directed to any of the FlexPak’s serial ports 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.
FlexPak-V1/V1G/V2 models are also capable of SBAS
positioning. This positioning mode is enabled using the
SBASCONTROLcommand. The following commands are typically
used to enable WAAS (North America) and EGNOS (Europe)
respectively:
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
To log data, use the LOGcommand. For example, to log the
pseudorange position to COM 2 every 30 seconds, enter the
following:
The ASSIGNLBAND command allows you to set OmniSTAR or
CDGPS base station communication parameters. It should
include a relevant frequency and data rate. The frequency
assignment can be made in Hz or KHz. For example:
Hz: assignlband omnistar 1536782000 1200
KHz: assignlband omnistar 1536782 1200
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.
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.
A value entered in Hz is rounded to the nearest 500 Hz.
To confirm you are tracking an L-Band signal, log the L-Band
status information by entering:
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.
log lbandstat
For example, if you are receiving CDGPS, the fifth field after the
header should be 00c2:
lbandstata com1 0 43.5 finesteering 1295
149951.671 00000000 976f 34461;
1547546977 46.18 4541.0 0.00 00c2 00f0 ...
To specify the correction source, use the PSRDIFFSOURCE
command as shown in the examples below:
PSRDIFFSOURCE OMNISSTAR
PSRDIFFSOURCE CDGPS
or,
otherwise it is left at the default AUTOMATIC.
ꢀ Refer to the OEMV Family Firmware Reference Manual for more

or FlexPak-V2) or SBAS commands and logs.

REAL-TIME KINEMATIC (RTK) POSITIONING
POST PROCESSING
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.
Post-mission data processing refers to when the GNSS data
collected by the receiver is processed after the entire data-
collection session is complete.
If you have any questions or comments regarding your FlexPak,
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.
