Kalman Filters


“How can we analyze data when we can’t directly measure data?”


Scientists love to analyze data. However, sometimes we may not be able to directly obtain data. For example, when NASA studies the temperature near their rocket thrusters, they can’t place a sensor directly connected since the heat of the flame will burn it up. So instead, how about we indirectly look at this data through other means, such as the surrounding temperature of space and infer the engine’s temperature with interpolation. This technique is known as a Kalman FIlter and is used by scientists and engineers from all over the world.
