This guide provides the basic information you need to set up and begin using your SPAN system.
SPAN SYSTEM COMPONENTS
A SPAN system requires the following primary components:
• A SPAN capable OEM6 receiver (enclosure or receiver card)
• An IMU (see the IMU Type column in Table 4, CONNECTIMU Commands)
• A quality, dual-frequency GNSS antenna such as the GNSS-502 or GNSS-802. See the NovAtel
website (www.novatel.com/products/gnss-antennas/) for information on a variety of quality antennas
available to meet your form factor and performance needs.
• Cables to connect the components. See Table 2, SPAN System Cables for FlexPak6 or Table 3,
SPAN System Cables for ProPak6.
• A power supply for the OEM6 receiver.
For the receiver power requirements, refer to the OEM6 Family Installation and Operation User
Manual (OM-20000128) or ProPak6 User Manual (OM-20000148) available on the NovAtel web site
(www.novatel.com/support/manuals/).
• A power supply for the IMU.
For the IMU power requirements, see Table 1, IMU Power Supply Requirements.

If you want to use the same power supply for the receiver and the IMU, make sure the power
supply meets the requirements of both the receiver and the IMU.
SET UP YOUR SPAN HARDWARE
Complete the following steps to set up and power your SPAN system.

This procedure focuses on a SPAN system with a FlexPak6 or ProPak6 receiver. For
information about SPAN system installation with other OEM6 receivers, see the SPAN on
OEM6 User Manual (OM-20000139) found on the NovAtel web site (www.novatel.com/support/
manuals/).
1. Mount the IMU and antenna securely to a vehicle.
For the simplest operation, align the Y-axis of the IMU with the forward axis (direction of travel) of the
vehicle. Ensure the Z-axis is pointing up.
Ensure that the GNSS antenna and IMU cannot move relative to each other. The distance and relative
direction between them must be fixed.

2. Connect the IMU to the receiver using the IMU interface cable.
• For a system with a FlexPak6, connect the IMU interface cable to the COM2 port. See Figure 1,
Connect FlexPak6 to IMU-ISA-100C, IMU-LN200, IMU-HG1900, IMU-µIMU, IMU-IGM, UIMU-HG1700,
UIMU-LCI or UIMU-LN200, on page 2.
For a system with a FlexPak6 and an IMU-ISA-100C, IMU-ISA-100, IMU-LN200, IMU-HG1900 or
IMU-µIMU, connect pin 5 to pin 9 on the I/O port. This changes the COM2 port protocol to RS-422.
• For a system with a FlexPak6 and an IMU-FSAS, IMU-CPT or IMU-KVH1750, connect the FlexPak Y
Adapter cable to the FlexPak6 ports labeled COM 2 and I/O. Then, connect the IMU to the FlexPak Y
Adapter cable using the IMU interface cable. See Figure 2, Connect FlexPak6 to IMU-KVH1750, IMUCPT or IMU-FSAS, on page 3.
• For a system with a ProPak6, connect the IMU interface cable to the COM3/IMU port. See Figure 3,
Connect ProPak6 to UIMU-HG1700, UIMU-LCI, UIMU-LN200, IMU-FSAS, IMU-ISA-100C, IMULN200, IMU-HG1900 or IMU-µIMU, on page 4.

6. Connect the receiver and the IMU to the power supply.
The power LED lights when the receiver is properly powered.

The FlexPak6 requires a power supply that provides 6-36 V DC and is capable of at least 5 W.
The ProPak6 requires a power supply that provides 9-36 V DC and is capable of at least 15 W.
If you are using the same power supply for the IMU, make sure the voltage range meets the
IMU requirements and there is sufficient power for both the receiver and the IMU.
If you are using the stack up interface cable (01019013) to connect an IMU-IGM to a FlexPak6,
the FlexPak6 provides power to the IMU-IGM.

Operation of the SPAN system is not affected by the order in which you power up the IMU and
receiver.

If you are using custom cables for your installation, rather than the NovAtel cables listed in
Table 2, be aware of the following.
The FlexPak6 provides an output voltage on pin 4 of COM 2 (POUT) that is at the same voltage
as the FlexPak6 power source. To ensure that any equipment you connect to COM 2 will not be
damaged, refer to the COM 2 pinout in the OEM6 Family Installation and Operation User
Manual found on the NovAtel web site at www.novatel.com/support/manuals/.
The ProPak6 provides an output voltage on pin 4 of COM1 and COM2 (Vout) that is the same
voltage at the ProPak6 power source. To ensure that any equipment you connect to COM1 or
COM2 will not be damaged, refer to the COM port pinout in the ProPak6 User Manual found on
the NovAtel web site at www.novatel.com/support/manuals/. On the ProPak6 this output voltage
can be turned on or off using the COMVOUT command.
Do not use the POUT output voltage to power an IMU.

If the receiver is installed in a vehicle, it is recommended that a dedicated battery be provided for the
receiver that is isolated from the engine starter battery. When a vehicle engine is started, the voltage
on the starter battery can dip to 9.6 V DC or cut-out to ancillary equipment causing the receiver and/or
IMU to lose lock and calibration settings.

For an alternative power source:
a. Cut the 12 V car adapter from the power cable.
b. Tie the exposed wires to a DC power supply.

c.

Be sure to connect the red and orange or green wires to the positive side of the power supply
and connect the black and brown or white wires to the negative side of the power supply.
Install a user supplied 6 A slow blow fuse at the alternate power source to protect the power
supply wiring and your warranty.
Since the 12V car adapter on the supplied adapter cable incorporates a 6A fuse, a user
supplied 6A slow blow fuse in a suitable holder must be used at the alternate power source to
protect both the power supply and your warranty.
The car adapter is not recommended for use if your power source is greater than 12V.

Basic configuration of the SPAN system is now complete. The inertial filter starts once the GNSS
solution is solved and the IMU is connected.
3. Enter the distance from the IMU to the GNSS antenna using the SETIMUTOANTOFFSET command.
The offset between the antenna phase center and the IMU axes must remain constant and be known
accurately. 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):
x_offset y_offset z_offset [x_stdev] [y_stdev] [z_stdev]
A typical RTK GNSS solution is accurate to a few centimetres. For the GNSS+INS system to have this
level of accuracy, the offset must be measured to within a centimetre. Any offset error between the two
systems shows up directly in the output position. For example, a 10 cm error in recording this offset will
result in at least a 10 cm error in the output.
If it is impossible to measure the IMU to GNSS antenna offset precisely, the offset can be estimated by
carrying out the Lever Arm Calibration Routine. Refer to the SPAN on OEM6 User Manual
(OM-20000139) for details.

The Lever Arm Calibration Routine is not available for the ADIS-16488, IMU-CPT, IMU-IGM,
HG1930 or STIM300 IMUs.
Configure SPAN Using NovAtel Connect™
Follow these steps to enable INS as part of the SPAN system using the NovAtel Connect software utility:
1. Start a NovAtel Connect session and establish a connection to the OEM6 receiver.
Refer to the receiver Quick Start Guide for information about connecting to the receiver.
2. Select Wizards | SPAN Alignment from the NovAtel Connect toolbar. This wizard takes you through the
steps to complete a coarse or kinematic alignment, select the type of IMU and configure the receiver
port to accept IMU data.
Configuration for Alignment
A coarse alignment routine requires the vehicle to remain stationary for at least 1 minute. If that is not
possible, an alternate, kinematic alignment routine is available. The kinematic or moving alignment is
performed by estimating the attitude from the GNSS velocity vector and injecting it into the SPAN filter as
the initial system attitude.

Static coarse alignment is not available for the ADIS-16488, IMU-CPT, IMU-IGM, HG1930 or
STIM300 IMUs. Use the kinematic alignment instead.

Regardless of system configuration and IMU orientation, the SETIMUORIENTATION and
VEHICLEBODYROTATION commands must be sent to the receiver before attempting a
kinematic alignment. See the SPAN on OEM6 Firmware Reference Manual (OM-20000144) for
information about these commands.
10
LOG SPAN DATA
Raw GNSS, IMU and navigation data (position, velocity, attitude) are available from the system as ASCII or
binary logs.
Data can be collected through NovAtel Connect using the Logging Control Window, or sent out the
receiver COM port to user-supplied data collection software.
For post-processing applications, collect the data shown in the Post-Process Data section of this guide.
For real-time applications, the GNSS+INS solution is available through the logs listed in the SPAN on
OEM6 Firmware Reference Manual (OM-20000144) including INSPOS, INSVEL, INSATT and INSPVA.
These logs can be collected at rates up to the IMU data rate; however, there are some rate restrictions.
Refer to the Data Collection section in the SPAN Operation chapter of the SPAN on OEM6 User Manual
(OM-20000139).
OPERATE THE SPAN SYSTEM
The system is ready to go once it is powered and the GNSS and INS are configured using the previously
shown commands.
Observe the status of the system in the NovAtel Connect INS Window or in the status field of any of the
INS solution logs (for example INSPOS, INSVEL, INSATT and INSPVA).

INS data is available after the receiver’s time status has reached FINESTEERING. Therefore,
an antenna must be connected for the system to function.
If performing a static alignment, allow the system to be stationary for at least 1 minute after the GNSS
solution is computed for its initial system alignment. If performing a kinematic alignment, move the vehicle
forward at a speed faster than 5 m/s. The following status stages may be observed:
• The status changes from INS_INACTIVE through DETERMINING_ORIENTATION,
WAITING_INITIALPOS and INS_ALIGNING as the initial alignment routine starts.
• The status changes to INS_ALIGNMENT_COMPLETE when the alignment is complete. After some
motion (stops, starts and turns), the attitude solution converges to within specifications and the status
changes to INS_SOLUTION_GOOD.
• The status may occasionally change to INS_SOLUTION_FREE. 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 notification that the
GNSS+INS solution is more reliable than the GNSS-only solution.
11
POST-PROCESS DATA
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.
Collect the following data for post-processing:
• From the base station
• RANGECMPB ontime 1
• RAWEPHEMB onchanged
• GLOEPHEMERISB onchanged (if using GLONASS)
• From the rover station(s)
• RANGECMPB ontime 1
• RAWEPHEMB onchanged
• GLOEPHEMERISB onchanged (if using GLONASS)
• RAWIMUSXB onnew
• IMUTOANTOFFSETSB onchanged
• VEHICLEBODYROTATIONB onchanged
• HEADINGB onnew (if using ALIGN dual antenna solution)
