NovAtel® developed the IMU-IGM-A1 for pairing with a SPAN® enabled GNSS receiver. Incorporating a MEMS inertial sensor, the IMU-IGM-A1 delivers the smallest and lightest IMU enclosure in our SPAN product portfolio.



The IMU-IGM-A1 can be configured from the factory as an integrated GNSS + Inertial Navigation System (INS) or as a standalone IMU sensor for pairing with an existing NovAtel SPAN receiver.

When configured as a standalone IMU, the IMU-IGM-A1 delivers a rugged product to build your SPAN application on.


  • Rugged enclosure
  • Small and lightweight
  • Regulated 10-30 VDC input
  • 200 Hz navigation solution and raw measurement output
  • Dedicated wheel sensor input


  • Available as a single enclosure GNSS + INS system or as a standalone IMU enclosure for pairing with a range of our SPAN enabled OEM6® products

SPAN: World Leading GNSS + INS Technology

SPAN technology brings together two different but complementary technologies: Global Navigation Satellite System (GNSS) positioning and inertial navigation. The absolute accuracy of GNSS positioning and the stability of Inertial Measurement Unit (IMU) gyro and accelerometer measurements are tightly coupled to provide an exceptional 3D navigation solution that is stable and continuously available, even through periods when satellite signals are blocked.

Improved Accuracy

NovAtel’s Advance® RTK improves real-time performance and accuracy. For more demanding applications, Inertial Explorer® software from our Waypoint® Products Group can be used to post-process SPAN data to provide the highest level of accuracy.
