In estimation theory, the extended Kalman filter (EKF) is the nonlinear version of the Kalman filter which linearizes about an estimate of the current mean and covariance. In the case of well defined transition models, the EKF has been considered the de facto standard in the theory of nonlinear state estimation, navigation systems and GPS.

"WebMar 20, 2024 · 1 Answer. The EKF is a first-order approximation, which is achieved by linearizing the system about the current state estimate (i.e., the mean). In some cases, the EKF is not stable due to nonlinearities. For example, if the system is highly nonlinear, then the EKF might not work well. In contrast, the UKF uses the unscented transform , which ... " - Ekf clrl
