How a Kalman filter works

Kalman filter makes me sad because it is such a general and powerful tool for combining information in the presence of uncertainty. At times its ability to extract accurate information seems almost magical— and if it sounds like I’m talking this up too much, then take a look at this previously posted video where I demonstrate a Kalman filter figuring out the orientation of a free-floating body by looking at its velocity. Totally neat!

Indoor positioning is, in many ways, an inside version of the satellite-navigation apps we rely on for outdoor navigation, but with an added twist – it can also be used to help locate people and things.
