Kalman Filter is one of the most important and common estimation algorithms. The Kalman Filter produces estimates of hidden variables based on inaccurate and uncertain measurements. As well, the Kalman Filter provides a prediction of the future system state, based on the past estimations. #### Appen support

The generic Kalman model. You're using the extended Kalman filter which, unlike the regular ("classic"?) Kalman filter, doesn't require a linear system. This is great because the system model is right above. Your states are position, speed, and yaw angle. So you do your predict steps: Predict the state estimate:
