Honeywell Aerospace has introduced the HGuide i700, an inertial measurement unit designed to deliver near-navigation-grade accuracy in a no-license-required package for unmanned air, land, and sea platforms.
The i700 draws on the sensor architecture and electronics of Honeywell’s HG3900 IMU, which the company introduced in June 2025 as a next-generation MEMS-based tactical-grade unit. The HGuide version trades the HG3900’s broader dynamic range for a constrained acceleration and spin-rate envelope optimized for longer-range navigation in GNSS-denied and GNSS-challenged environments — a profile suited to UAS, unmanned ground vehicles, unmanned surface vessels, and stabilized payloads operating without reliable satellite positioning.
The no-license-required classification is the product’s primary commercial differentiator. Export-controlled inertial systems require government authorization that adds time and complexity to integration programs, particularly for international customers and commercial developers working across multiple markets. By limiting the i700’s performance envelope to remain below export control thresholds, Honeywell is positioning it as a drop-in option for integrators who need near-navigation-grade inertial performance without the procurement friction of a controlled part.
“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, Navigation and Sensors, Honeywell Aerospace.
The i700 joins the HGuide i300 and i400 in Honeywell’s no-license inertial product line, extending the suite’s ceiling toward navigation-grade performance. Honeywell describes the unit as suited to mobile mapping and surveying systems, robotics and industrial automation, and long-duration unmanned ground and surface platforms in addition to aerial applications.
