provided in the NovAtel GPS PC Utilities setup program.  
5. Apply power to the SPAN-CPT. It is recommended that you

1 CD containing PC Utilities and product documentation  
1 User Manual postcard for requesting printed manuals  
Complete the following steps to set up and power your  
SPAN-CPT system.  
ADDITIONAL EQUIPMENT REQUIREMENTS  
1. Mount the SPAN-CPT enclosure and antenna securely to a  
vehicle. For the simplest operation, the Y-axis of the  
SPAN-CPT should be aligned with the forward axis  
(direction of travel) of the vehicle. The Z-axis should be  
pointing up. Ensure that the GNSS antenna and enclosure  
cannot move relative to each other. The distance and rela-  
tive direction between them must be fixed.  
The following additional equipment is needed for a basic setup:  
®
• A Windows -based PC with an RS-232 or USB port  
4. Select Serial from the Type list.  
5. Select the computer port the SPAN-CPT is connected to  
• A power supply of +9 to +18 V DC  
from the Port list.  
• A quality dual frequency GNSS antenna such as the  
GPS-702, or GPS-532 for airborne/high speed applications  
For L-Band corrections use the GPS-702L antenna  
6. Set the COM port for the receiver to communicate through.  
7. Select 115200 from the Baud Rate list.  
COMMUNICATE WITH THE SPAN-CPT SYSTEM  
8. Ensure the Hardware Handshaking box is not checked.  
9. Click the OK button to save the new device settings.  
Serial or USB communication can be done using the NovAtel  
Connect software (installed with the PC Utilities) or a standard  
terminal program, such as Hyperterminal.  
• A TNC to appropriate antenna connector RF cable  
INSTALL THE PC UTILITIES  
Before setting up your SPAN-CPT system, install NovAtel’s PC  
Utilities on the Windows-based computer that you will use to  
communicate with it. This computer must have an RS-232 DB-9  
or USB port.  
1. Start up the computer.

DATA FOR POST-PROCESSING  
If you have any questions or comments regarding your SPAN-CPT  
The system is ready to go once it is powered and the INS and  
GNSS are configured using the previously shown commands.  
MEASURE THE LEVER ARM  
Post-processing requires collection of simultaneous data from  
the base and rover stations. This includes accurate coordinates  
of the base station and accurate measurement of the IMU to  
antenna separation.

Enter the distance from the IMU to the GNSS antenna using the  
SETIMUTOANTOFFSET command. The offset between the  
antenna phase centre and the IMU axes must remain constant  
and be known accurately (m). The X (pitch), Y (roll) and Z  
(azimuth) directions are clearly marked on the IMU enclosure.  
The SETIMUTOANTOFFSET parameters are (where the  
standard deviation fields are optional):  
Observe the status of the system in the INS window of NovAtel  
Connect or in the status field of any of the INS solution logs (for  
example INSPOS, INSVEL, INSATT and INSPVA).  
Collect the following data for post-processing:  
• From the base station  
1-403-295-4900 (International)  
INS data is available once there is a good GNSS solution.  
Fax:  
1-403-295-4901  
Therefore, an antenna must be connected for the system to  
function.  
RANGECMPB ontime 1  
RAWEPHEMB onnew  
x_offset y_offset z_offset [x_stdev] [y_stdev] [z_stdev]  
• From the rover station(s)  
For the integrated INS/GNSS system to have the best level of  
accuracy, the offset should be measured to within a millimetre.  
Any error in this measurement will show up in the output  
position. For example, a 10 cm error in measuring this offset will  
result in at least a 10 cm error in the output. If the system is  
installed in line with the vehicle, this is the only configuration  
required.  
The following status stages may be observed:  
RANGECMPB ontime 1  
• The status changes from INS_INACTIVE to INS_ALIGNING  
once the receiver computes a GPS solution.  
RAWEPHEMB onnew  
RAWIMUSB onnew  
• The default alignment method for CPT is a kinematic align-  
ment. The INS solution will begin once the vehicle starts to  
move faster than 1.15 m/s. Alternatively, you can set the atti-  
tude of the system manually by using the SETINTAZIMUTH  
command. See the SPAN-CPT User Manual for more details  
on how to use this command.

SPAN-CPT system output is compatible with Inertial Explorer  
post-processing software from the Waypoint Products Group,  
NovAtel Inc. Visit our website at www.novatel.com for details.  
LOG SPAN-CPT DATA  
Raw GNSS, IMU and navigation data (position, velocity, attitude)  
are available from the system as ASCII or binary logs.  
• The status changes to INS_ALIGNMENT_COMPLETE  
when alignment is completed. After some motion (stops,  
starts and turns), the attitude solution converges to within  
specifications, and the status changes to  
Data can be collected through Connect using the Logging  
Control window, or sent out the IMU COM port to user-supplied  
data collection software.  
INS_SOLUTION_GOOD.  
For post-processing applications, collect the data shown in the  
• The status may occasionally change to  
Data for post-processing section in this guide.  
INS_BAD_GPS_AGREEMENT. This status indicates that  
the inertial solution has detected poor quality GNSS  
positions from the receiver due to limited satellite visibility or  
high multipath conditions. The inertial filter may choose to  
disregard this information and wait for the GNSS quality to  
improve. The solution is still valid during these times, it is  
simply a warning flag that the GNSS/INS solution is more  
reliable than the GNSS-only solution.  
For real-time applications, the GNSS/INS solution is available  
through the logs listed in the SPAN-CPT User Manual including  
INSPOS, INSVEL, INSATT and INSPVA. These logs can be  
collected at rates up to the IMU data rate (100 Hz); however,  
there are some rate restrictions. Refer to the Data Collection  
section in the SPAN Operation chapter of the SPAN-CPT User  
Manual.
