Honeywell has expanded its navigation portfolio with the HG3900 inertial measurement unit (IMU), a lightweight and low-power tactical-grade device with accuracy and reliability comparable to larger near-navigation-grade IMUs.
<p>Honeywell will showcase the HG3900 IMU, along with the rest of its navigation products, at the Joint Navigation Conference in Cincinnati June 2-5, including a <a target="_blank" href="https://www.ion.org/jnc/abstracts.cfm?paperID=15575" target="_blank" rel="noreferrer noopener">feature session</a> on June 4.</p> <p>The HG3900 is comprised of all-silicon microelectromechanical system (MEMS) gyroscopes and accelerometers, which enables a significant reduction in size, weight and power from comparable IMUs using traditional technologies. Its advanced sensors significantly boost its performance by offering a 20-time improvement over other Honeywell MEMs.</p> <p>The HG3900 is designed for backward compatibility. As the highly successful Honeywell HG1900 IMU nears its end of life, the HG3900 will be offered in a nearly identical package to enable an easy transition for existing HG1900 customers.</p> <p>The HG3900 IMU has successfully completed full environmental testing by the U.S. Army and Navigation Technology Associates (NTA), meeting requirements while under demanding environmental conditions including high vibration and dynamic temperature changes.</p> <p>“Our HG3900 IMU is an ideal solution for customer applications requiring tactical or near-nav grade performance in a small, lightweight package,” said Matt Picchetti, vice president and general manager, Navigation and Sensors, Honeywell Aerospace Technologies. “Extensive Honeywell and customer testing demonstrates that our new IMU offers superior real-world performance in a smaller package.”</p> <p>IMUs are widely used on aircraft, ships, spacecraft and other applications where precision positioning and navigation are critical. The importance of these devices has intensified considerably over the past decade with the significant growth in autonomous vehicles and other autonomy use cases. IMUs utilize gyroscopes, accelerometers and electronics to determine where a vehicle is, what direction it is going, at what speed and how far it has travelled.</p> <p>Advanced MEMS IMUs such as the HG3900 are highly resilient and can provide accurate navigation and orientation data with or without GNSS inputs. They can function independently for extended periods when GNSS signals are jammed, spoofed or unavailable.</p> <p>The design verification process will continue into 2026 with initial production and deliveries to begin in late 2026 or early 2027. Honeywell is accepting orders for pre-production units for delivery in 2026.</p> <p><p>The post <a target="_blank" rel="nofollow" href="https://www.gpsworld.com/honeywell-adds-imu-to-navigation-lineup/">Honeywell adds IMU to navigation lineup</a> first appeared on <a target="_blank" rel="nofollow" href="https://www.gpsworld.com">GPS World</a>.</p></p>
