Contribute to Shelfcol/gps_imu_fusion development by creating an account on GitHub. To fuse GPS and IMU data, this example uses an extended Kalman filter (EKF) and tunes the filter parameters to get the optimal result. The property values set here are typical for low-cost MEMS This example shows how you might build an IMU + GPS fusion algorithm suitable for unmanned aerial vehicles (UAVs) or quadcopters. "INS/GPS" refers to the entire system, including the filtering. Fusing accelerometer, gyroscope, and GPS data with nonholonomic constraints is a common configuration for ground vehicle pose estimation. This fusion filter uses a continuous-discrete extended Kalman filter (EKF) to track orientation (as a quaternion), angular velocity, position, velocity, acceleration, sensor biases, and the geomagnetic vector. Typically, ground vehicles use a 6-axis IMU sensor for pose estimation. Extended Kalman Filter algorithm shall fuse the GPS reading (Lat, Lng, Alt) and Velocities (Vn, Ve, Vd) with 9 axis IMU to improve the accuracy of the GPS. We’ll go over the structure of the algorithm and show you how the GPS and IMU both contribute to the final solution so you have a more intuitive Sensor Fusion and Tracking Toolbox™ enables you to model inertial measurement units (IMU), Global Positioning Systems (GPS), and inertial navigation systems (INS). gps_imu_fusion with eskf,ekf,ukf,etc. In our case, IMU provide data more frequently than GPS.
