The HG1930 is a small, low cost Micro Electromechanical Systems (MEMS) Inertial Measurement Unit (IMU) manufactured by Honeywell. It provides tactical grade performance for unmanned vehicles and other commercial and/or military guidance applications. When integrated with NovAtel's Synchronous Position, Attitude and Navigation (SPAN) technology, this IMU is ideal for airborne and ground applications that require accurate 3D position, velocity and attitude data.

Combining SPAN and MEMS Technology

A proprietary MEMS Interface Card (MIC) couples the HG1930 with SPAN receivers, offering a unique, powerful GNSS+INS system for weight and size constrained applications. Designed as a board stack configuration for ease of integration, the MIC can interface directly with NovAtel's small form factor OEM615™ SPAN receiver.

The HG1930 is also available as a stand alone product so integrators can easily pair it with an existing SPAN receiver.
