You know its current velocity, so you can calculate where it should be in one second. However, wind gusts and motor efficiency variations add minor errors.

By establishing this intuitive framework first, Kim ensures that when the complex matrix algebra finally appears later in the book, the reader already understands the purpose of every term.
A Kalman filter is a recursive algorithm that uses a combination of prediction and measurement updates to estimate the state of a system. It is based on the state-space model, which represents the system dynamics and measurement process. The algorithm uses the previous state estimate and the current measurement to produce a new state estimate. The Kalman filter is optimal in the sense that it minimizes the mean squared error of the state estimate. This link or copies made by others cannot be deleted
The Kalman filter has various applications, including:
