Ah, that first step is a big critical one! "Data – sets of facts and beliefs that describe the real world. All observations are captured as data." The world is full of wonderful algorithms, but if they are fed garbage the final result is garbage. As I recall is was a missed placed decimal point that crashed the first Surveyor that was suppose to land on the moon, the Kalman filter working just fine, it was bad data. I was static electricity that scrambled the data fed the Kalman on the FB-111, and the computer sent me a message, "I am shutting down, we cannot get there from here." One of the Mars Explorers crashed when the filter got centimeters when it was expecting inches. No sign over my door, just a plague on the wall. GARBAGE IN, GARBAGE OUT!
