Honeywell's HGuide n380 is a new inertial navigation system that communicates position, orientation, and velocity of an object—such as an autonomous vehicle or unmanned aerial vehicle (UAV)—even when global navigation satellite signals are unavailable. Smaller, lighter, and lower-priced than its previous inertial navigation systems, the company says HGuide n380 is designed to withstand harsh environments in the air, on land, or at sea.

“We recognized a need for a small, high-performance inertial navigation system in areas like 3D mapping, surveying, and other applications where space is at a premium and performance cannot be compromised,” said Chris Lund, Offering Management Senior Director, Navigation and Sensors, Honeywell Aerospace. “We responded by developing the HGuide n380 inertial navigation system, which provides our customers with proven, cost effective inertial sensor technology, created for aerospace applications, but that can be integrated into almost any architecture.”

This new inertial navigation system is composed of the company’s HGuide i300 inertial measurement unit (IMU), a global navigation satellite system (GNSS) receiver, and its proprietary sensor fusion software, which is based on the algorithms used for navigation on millions of aircraft every day. Inputs from these components are fused together to determine position, orientation, and velocity to deliver critical navigation information even in areas where a satellite signal is degraded or altogether unavailable, such as canyons, bridges, tunnels, mountains, parking garages, or dense forests.
