How uncertain am I about this prediction? 2. Update (Measurement Update)
It smooths out jittery data without the lag associated with simple moving averages.
If you trust only the GPS, your speed jumps erratically. If you trust only the speedometer, your speed gradually becomes completely wrong. is the mathematical bridge that optimally combines these two imperfect sources of information to give you the most accurate possible estimate of the car's true speed.
A Kalman filter is a algorithm that uses a combination of prediction and measurement updates to estimate the state of a system. It is a recursive algorithm, meaning that it uses the previous estimates to compute the current estimate. The Kalman filter consists of two main steps:
