12 SPAN-IGM User Manual Rev 2
Chapter 1 Introduction
1.2 System Components
The SPAN-IGM system consists of the following components:
• SPAN-IGM Integrated GNSS + INS unit
This unit has 3 accelerometers, 3 gyroscopes (gyros) and a NovAtel OEM615 receiver. Excellent
acquisition and re-acquisition times allow this receiver to operate in environments where very
high dynamics and frequent interruption of signals can be expected.
• GNSS antenna
A quality, dual frequency GNSS antenna such as the GPS-702-GG or ANT-A72GA-TW-N for
airborne/high speed applications. 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.
• PC software
Real-time data collection, status monitoring and receiver configuration is possible through the
NovAtel Connect software utility, see Configure SPAN with Connect on page 25.
There are two SPAN-IGM models available, the SPAN-IGM-A1 and the SPAN-IGM-S1. These models
have the same features and functionality. They also install and operate in the same manner. For these
reasons, the majority of this manual uses the term SPAN-IGM, which refers to both models.
Where the two models differ is in the IMU performance.
• The SPAN-IGM-A1 uses the ADIS-16488 IMU. For details about this model, see SPAN-IGM-A1
Technical Specifications on page 52.
• The SPAN-IGM-S1 uses the STIM300 IMU. For details about this model, see SPAN-IGM-S1
Technical Specifications on page 54.
1.3 Scope
This manual contains sufficient information about the installation and operation of the SPAN-IGM system.
It is beyond the scope of this manual to provide details on service or repair. Contact your local NovAtel
dealer for any customer-service related inquiries, see Customer Support on page 7.
A SPAN-IGM system requires the addition of accessories, an antenna and a power supply.
The SPAN-IGM utilizes a comprehensive user-interface command structure, which requires
communications through its communications ports. The SPAN on OEM6 Firmware Reference Manual
(OM-20000144) describes the INS specific commands and logs. For descriptions of other commands
and logs available for SPAN-IGM, refer to the OEM6 Family Firmware Reference Manual
(OM-20000129). These manuals are available on the NovAtel website (www.novatel.com/support/
firmware-software-and-manuals/product-manuals-and-doc-updates/). It is recommended that these
documents be kept together for easy reference.
SPAN-IGM output is compatible with post-processing software from NovAtel's Waypoint
