Kalman Filtering: Still More Work to be Done

James L. Farrell

Abstract:	A suggestion of significant recommendations affecting Kalman filter practices at this late date is sure to invite skepticism. Yet after more than a half century – including various other reviews/revisits/post-mortems – appreciable need is still evident from several sources, many of which are either recent or widely followed, or external. This critique is not aimed in any particular direction nor toward any specific sources; the need for greater thoroughness in application has industry-wide ramifications; those external sources through lack of understanding can impose their will upon the navigation community, sometimes with major adverse consequences. Some of what-remains-to-be-said is from subtle issues, subliminally realized but by and large underrated. Other items to be discussed here are thus far almost universally overlooked. Still others are known but have fallen victim to custom. With current heightened interest in robust operation an enormous potential payoff is offered by reclaiming benefits that have largely escaped wide acceptance or even recognition.
