High-performance tactical grade IMU combines with SPAN technology from Hexagon | NovAtel to deliver 3D position, velocity and attitude solution
World-leading GNSS+INS technology
SPAN GNSS+INS technology brings together two different but complementary technologies: Global Navigation Satellite System (GNSS) positioning and inertial navigation. The absolute accuracy of GNSS positioning and the stability of Inertial Measurement Unit (IMU) gyro and accelerometer measurements are deeply coupled to provide an exceptional 3D navigation solution that is stable and continuously available, even through periods when satellite signals are blocked.
The IMU-ISA-100C features Northrop-Grumman Litef GMBH’s proven inertial measurement technology offering exceptional performance when paired with a SPAN-enabled receiver from NovAtel. A near navigation grade sensor, the IMU‑ISA‑100C contains fiber optic gyros and fully temperature compensated Micro Electromechanical Systems (MEMS) accelerometers. The IMU-ISA‑100C operates from 10-34 VDC and interfaces with a receiver from NovAtel through a highly reliable IMU interface. IMU measurements are used by the SPAN-enabled receiver to compute a blended GNSS+INS position, velocity and attitude solution at rates up to 200 Hz.
