This functional block diagram of the n580 inertial/GNSS inertial navigation system illustrates how the gyro and accelerometer data from the HG4930 IMU flows through Honeywell’s world-class calibration and compensation software and is provided into the sensor fusion software or Kalman filter. GNSS data is also inputted into the sensor fusion software. Additional aiding, such as odometry, may also be provided. The output provides very accurate position, velocity, time, heading, pitch, and roll. This system is used in many critical applications.
