Inertial Sensor Fusion

Inertial navigation with IMU and GPS, sensor fusion, custom filter tuning

Inertial sensor fusion uses filters to improve and combine readings from IMU, GPS, and other sensors. To model specific sensors, see Sensor Models.

For simultaneous localization and mapping, see SLAM.
