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


  • Regulated 10-30 VDC input
  • 125 Hz navigation solution and raw measurement output
  • Dedicated wheel sensor input


  • Small, lightweight and rugged
  • Tactical grade performance
  • Commercially exportable
  • Optimized for SPAN on OEM6 enclosures

SPAN Enabled MEMS Enclosure

NovAtel developed the IMU-IGM-S1 for pairing with a SPAN enabled GNSS receiver. Incorporating Sensonor’s STIM300 MEMS IMU, the IMU-IGM-S1 delivers the smallest and lightest tactical grade IMU enclosure in our SPAN product portfolio.

The IMU-IGM-S1 delivers a rugged product on which to build your SPAN application.

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.
