Honeywell Develops MEMS IMUs for Unmanned Vehicles

Published: 02 Oct 2017 | Author: Caroline Rees

HG4930 MEMS IMU for AUVsHoneywell, a leading provider of navigation technologies for unmanned aerial vehicles (UAVs) and other robotic systems, has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Platinum’ profile highlights the benefits of Honeywell’s Micro-Electro-Mechanical System (MEMS) Inertial Measurement Units (IMUs) as motion-sensing solutions for all kinds of unmanned vehicles, including UAVs, UGVs and AUVs.

The HG1120 and HG4930 IMUs employ advanced MEMS gyroscopes and accelerometers (as well as magnetometers in the HG1120) to meet a broad range of robotic application needs, such as precision agriculture, surveying and mapping, platform stabilization, navigation, and motion compensation. Both systems feature an internal environmental isolation system designed to attenuate unwanted inputs commonly encountered in real-world applications, making the IMUs rugged enough for even the most demanding environments.

The extremely small footprint of these IMUs make them ideal for space-constrained and SWAP-conscious unmanned vehicle applications. With industry standard communication interfaces, both units are easily integrated into a variety of architectures.

HG1120 MEMS IMU for UAVsThe HG1120 high performance IMU includes MEMS gyroscopes, accelerometers, and magnetometers. It is available in three different performance grades, each with a range of user configurable options with selectable output data rates and filtering, and RS-422 Asynchronous and SPI Interface protocols. CAN interface is available upon request.

The HG4930 very high performance IMU, with superior repeatability and stability, is also available in three different performance grades, each with RS-422 Asynchronous and SDLC standard protocols. The system is ideal as a smaller, lower power, and cost effective replacement for a fiber optic gyro (FOG) IMU.
