Honeywell HGuide i300 MEMS IMU


The Honeywell HGuide i300 inertial measurement unit (IMU) provides an advanced precision inertial solution on land, air or sea with its accurate and dependable guidance, control and pointing capabilities under the most demanding environments.



The Honeywell HGuide i300 is the smallest member of Honeywell’s suite of non-itar, micro-electro-mechanical system (MEMS) IMUs.

It uses proven inertial sensor technology that was created for aerospace applications and is perfect for customers who need an advanced precision inertial solution on land, air or sea.

The HGuide i300 includes MEMS accelerometers and gyroscopes. It also uses an internal environmental isolation system that attenuates unwanted inputs often encountered in the real world. Proprietary design features, including the internal isolation, ensure the HGuide i300 is rugged enough to meet the requirements of the most demanding users.

The HGuide i300 can be integrated into any architecture easily by using a wide range of input voltages and standard communications interfaces. The i300’s low power requirements, light weight and extremely small size makes it ideal for a wide range of industrial applications, including UGVs, UAVs, transportation, stabilized platforms, survey and mapping, robotics, oil and gas, marine, industrial equipment, communications, AUVs and agriculture.

The i300 IMU is available in two different performance grades.


  • Scalable, cost-effective solution for any application
  • Performance levels and costs aligned with user requirements
  • Configurable options with selectable filtering and output data rates
  • Multiple communication protocols that are configurable
  • Proven reliability, dependability and ruggedness
