supply, install NovAtel’s PC Utilities.  
A Windows-based PC with an RS-232 DB-9 or USB port  
One of the following:  
1. Start up the PC.  
This guide provides the basic information you  
need to set up and begin using your new  
FlexPak-V1/V1G/V2. For more detailed  
your receiver, please refer to the user manuals  
provided on the accompanying CD. The most  
To order a printed copy of the manuals, free of charge, follow the  
instructions given on the enclosed User Manuals postcard.  
2. Insert the accompanying CD in the CD-ROM drive of the  
computer.

3. Select Install the OEMV GPS PC Utilities from the window  
that is automatically displayed. If the window does not  
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  
use the OmniSTAR service (visit http://www.omnistar.com and  
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  
on individual L-Band (FlexPak-V1 only), GLONASS (FlexPak-V1G  
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.

RT-2 (OEMV-2) and RT-20 (OEMV-1, OEMV-1G and OEMV-2),  
all with AdVance RTK, are real-time kinematic software products  
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  
Once your base and rover are set up, you can configure them for  
RTCA, RTCM, RTCMV3, CMR+ or CMR corrections. An RTCM  
example follows (replace the latitude, longitude and height  
coordinates shown with those of your base):  
manufacturers when using RTCM messaging.  
RT-2 and RT-20 are supported by GPS-only and  
GPS+GLONASS OEMV-based models. Also, RT-20 with  
GPS+GLONASS provides faster convergence.
