Honeywell launches HGuide i700 IMU for GNSS-denied navigation

LONDON - Honeywell has introduced the HGuide i700 inertial measurement unit (IMU), designed to provide near navigation-grade performance for uncrewed air, land, and sea platforms operating in contested or GPS-denied environments.

The HGuide i700 combines high-accuracy sensing with a no-license-required (NLR) classification, enabling global deployment without export restrictions that typically apply to higher-performance navigation systems. The unit is intended to support autonomous systems, robotics, and precision-guided applications that require reliable positioning and orientation data.

The IMU leverages sensor and electronic architecture derived from Honeywell’s HG3900 IMU, a navigation-grade system widely used in aerospace and defense applications. The HGuide i700 is optimized to deliver extended navigation performance in Global Navigation Satellite System (GNSS)-denied environments while maintaining a compact size, rugged design, and low power consumption.

"The HGuide i700 offers strong GNSS-denied performance by limiting maximum acceleration and spin rates in a license-free package that simplifies the complexity of system development while preserving reliability," said Matt Picchetti, vice president and general manager of Navigation and Sensors at Honeywell Aerospace.

Honeywell says the system is designed to streamline integration and reduce development timelines by providing a balance between performance and regulatory accessibility. The unit is part of the company’s broader HGuide family of inertial navigation solutions aimed at simplifying system architecture for integrators.

Potential applications include uncrewed aerial, ground, and maritime vehicles, as well as mobile mapping and surveying systems, long-endurance autonomous platforms, robotics, and stabilized payloads or pointing systems.

Honeywell has developed inertial navigation technologies for more than 30 years and was an early adopter of microelectromechanical systems (MEMS) for navigation applications. For more information, please visit https://aerospace.honeywell.com.
