The IMU-HG1900 offers a hybrid package of Honeywell’s Micro Electromechanical Systems (MEMs) Gyros and RBA accelerometers. Our Synchronous Position, Attitude and Navigation (SPAN) technology combines Global Navigation Satellite System (GNSS) positioning and Inertial Navigation Systems (INS) to provide a 3D navigation and attitude solution.

Purchase the IMU-HG1900 as a complete assembly with the IMU in an environmentally sealed enclosure or as a stand-alone OEM product to pair it with a SPAN enabled receiver.

NovAtel CORRECT™ and Inertial Explorer® technologies allow for higher accuracy and performance in the most demanding applications.
