Randy Atkins:  Rudolf Kalman invented the Kalman Filter to get more information about rapidly changing conditions –- like precise location of an aircraft – than sensors can actually measure.

Robert Bass:  You can estimate all the things that normally would require a big suite of instruments, and you don’t need them anymore.

Randy Atkins:  Robert Bass is an engineer who worked with Kalman on the filter.  It isn’t a physical filter, but a series of mathematical steps called an algorithm.

Robert Bass:  A modern digital computer can do it so fast that a human being thinks it’s happening instantaneously, as far as we’re concerned it’s happening in real time.

Randy Atkins:  And that's vital for applications like auto-piloting our airplanes.  With the National Academy of Engineering, Randy Atkins, 103 point 5 F-M, WTOP Radio.
