What is Kalman filter good for?
Kalman filters are used to optimally estimate the variables of interests when they can't be measured directly, but an indirect measurement is available. They are also used to find the best estimate of states by combining measurements from various sensors in the presence of noise.
What filter is better than Kalman?
Particle Filter
Particle FIlters can be used in order to solve non-gaussian noises problems, but are generally more computationally expensive than Kalman Filters. That's because Particle Filters uses simulation methods instead of analytical equations in order to solve estimation tasks.
Where is Kalman filter used?
A common application is for guidance, navigation, and control of vehicles, particularly aircraft, spacecraft and ships positioned dynamically. Furthermore, Kalman filtering is a concept much applied in time series analysis used for topics such as signal processing and econometrics.
What is Kalman filter method?
The Kalman Filter is an efficient optimal estimator (a set of mathematical equations) that provides a recursive computational methodology for estimating the state of a discrete-data controlled process from measurements that are typically noisy, while providing an estimate of the uncertainty of the estimates.
