The µIMU-IC features Northrop Grumman Litef GmbH’s proven inertial measurement technology offering exceptional performance when paired with a NovAtel Synchronous Position, Attitude and Navigation (SPAN) receiver. The µIMU interfaces with NovAtel’s OEM6® and OEM7 receivers through a highly reliable IMU interface. IMU measurements are used by the SPAN receiver to compute a blended GNSS+INS position, velocity and attitude solution up to 200 Hz.

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