Autonomy Spotlight: Honeywell HG4930 S-Class IMU Stabilizes Antennas, Cameras and More!

July 10, 2019 | Author: Ray Sturm

Honeywell offers high-performance, non-ITAR inertial measurement units and navigators for demanding use cases that require reliable data in challenging environments.

Honeywell has the right answer for commercial and industrial applications where control and stability are essential. For example, our micro-electro-mechanical system (MEMS) inertial measurement units (IMUs) hold antennas and cameras steady and isolate them from shock and vibration.

Our sensors detect the slightest vibrations in a vehicle or other moving platform on which an antenna or camera is mounted. These measurements are fed into a control system, which corrects or stabilizes the platform. Without an IMU, communication can be degraded or lost and images can be shaky or out of focus. Think of Uncle Phil’s camerawork at your cousin’s wedding.

In the case of antennas that are used to send and receive transmissions from satellites, aircraft and mobile ground stations, IMUs provide real-time data that helps keep the antenna correctly oriented.

This is especially important when antennas are mounted on a moving vehicle like a ship, helicopter, drone or off-road vehicle. The IMU senses the motion of the vehicle and provides real-time data that enables the platform to compensate for movement, so the antenna stays engaged and locked onto the signal.

The sensors are also used in camera stabilization systems for industrial and broadcast applications. Professional videographers need to produce images that are sharp and steady, even when they’re using a helicopter, drone, crane or camera boom to capture the shot. They’ve been using IMUs to stabilize cameras for decades in conditions as varied as a movie set, sporting event or police chase.

IMUs use gyroscopes and accelerometers to sense rotation and acceleration. They can be used in any application for which it’s important to accurately measure and compensate for vibration and motion under the most challenging of conditions. In addition to helping stabilize antennas and cameras, IMUs are also used on robots, autonomous vehicles and drones.

Electronic sensors have replaced mechanical gyros in many applications, including camera and antenna stabilization. In the past, the electronic sensors were often fiber optic gyros (FOGs), but these days engineers are using MEMS IMUs to reduce cost and weight but maintain performance. 

Honeywell’s HGuide suite of non-ITAR, MEMS inertial sensors and navigators are designed for industrial applications and perform well in environments prone to heavy vibrations where cameras and antennas are used.  

Recently, Honeywell announced its newest IMU, the Honeywell HG4930 S-Class (MEMS) IMU, a great option for customers looking to optimize latency and bandwidth without sacrificing performance.

We’re continually looking for new ways to apply our unique expertise in inertial sensing and navigation technology to industrial applications such areas as agriculture, autonomous vehicles, industrial equipment, robotics, survey/mapping, stabilized platforms, transportation and unmanned aerial vehicles.
