The really clever part is the difference between the prediction and the measured outcome can be used to adapt the model on the fly. This means that the filter actually learns what its parameter values are.

We used this to refine GPS placement and orientation on the vehicle as it went about it usual work.

We were developing a GPS receiver when the GPS constellation was still being launched into orbit. I developed Kalman filters, written in C, to lock onto the GPS signal and decode the GPS p-code and CA-code. It was a fun endeavor and one of my first efforts out of college, self taught C for this project. Thanks for posting the article. This brought back fond memories.
