the particle Kalman filter, the iterative EnKF and extended Kalman filter, morphing methods, ‘Running in place,’ and the ‘quasi-outer loop.’ While these methods have been applied for simple models, many have not been tested on high-dimensional systems, such as full-physics atmospheric models...
Understanding the Basis of the Kalman Filter Via a Simple and Intuitive Derivation [Lecture Notes]...
“The math for implementing the Kalman filter appears pretty scary and opaque in most places you find on Google.” Indeed. I’ve tried to puzzle my way through the Wikipedia explanation of Kalman filters on more than one occasion, and always gave up. I was able to walk through your explan...
Watch this video for an explanation of how Kalman filters work. Kalman filters combine two sources of information, the predicted states and noisy measurements, to produce optimal, unbiased estimates of system states. The filter is optimal in the sense that it minimizes the variance in the es...

(I got a question about why I list position and velocity. The simple answer is if you think of a quadcopter it can be pointed in one direction while flying/moving in another direction.) There are two types of equations for the Kalman filter. The first are the prediction equations. These...
Kalman Filter So here we are going to set up ourvery simple Kalman Filter. This example is not a great example of a complete Kalman Filter, I have removed some components that aren't needed in our simple case. If you want more information, and the full equation for a Kalman Filter, yo...
