The HG1900 Inertial Measurement Unit (IMU) offers a hybrid package of Honeywell's Micro Electromechanical Systems (MEMs) Gyros and RBA accelerometers. Economical, robust and small, the low power HG1900 provides high end tactical grade performance for commercial and military guidance and navigation 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 NovAtel MEMS Interface Card (MIC) couples the HG1900 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 interfaces directly with NovAtel's small form factor OEM615™ SPAN receiver.

The HG1900 is also available as a stand alone product so integrators can easily pair it with an existing OEM6® SPAN receiver.
