Perform sensor modeling and simulation for accelerometers, magnetometers, gyroscopes, altimeters, GPS, IMU, and range sensors. Analyze sensor readings, sensor noise, environmental conditions and other configuration parameters. Generate trajectories to emulate these sensors traveling through a world and calibrate the performance of your sensors.
To fuse multiple sensors or use other localization algorithms, see Localization and Pose Estimation.
