IMU-FSAS banner

The IMU-FSAS is a tactical grade IMU from iMAR GmbH. The custom NovAtel interface of the IMU integrates easily into a NovAtel SPAN enabled GNSS+INS receiver such as the FlexPak6™ or ProPak6™.


IMU-FSAS Brochure

IMU measurements are sent from the IMU-FSAS to the GNSS+INS receiver where a blended GNSS+INS position, velocity and attitude solution is generated at up to 200 Hz. An optional interface for magnetic or optical encoder style wheel sensors is available for ground applications.


  • Closed loop fiber optic gyros and servo accelerometers
  • 200 Hz data rate
  • Wheel encoder input capability
  • SPAN INS functionality


  • 35,000 hour MTBF
  • No export approval required for most countries and applications
  • Easy integration with a NovAtel SPAN capable GNSS+INS receiver

Advantages of IMU-FSAS

The low noise and stable biases of the accelerometer and gyro sensors mean this IMU is well suited for ground or airborne survey applications or general positioning and navigation in locations where standard GNSS receivers are not sufficient. For commercial applications, the IMU-FSAS does not require formal export authorization from Germany or Canada.

Improve IMU-FSAS Accuracy

Take advantage of our Advance® RTK as well as support for other satellite based augmentation systems such as L-Band or SBAS to improve real-time performance and accuracy. For more demanding applications, Inertial Explorer® post-processing software from our Waypoint® Product Group can be used to post-process IMU-FSAS data and offers the highest level of accuracy with the system.
