I hesitate to speculate but the book I read that talked of Kalman filters and two people I know who messed with them said they are opaque and tricky to get right[1]. Hard to understand what the filter constants mean, and buggy software implementations 'sort of work' then break.
Nonsense, Kalman filters are well understood and widely used in spacecraft attitude dynamics and control systems. In fact, I'd argue that a Kalman filter is industry standard for that work. It's typical on teams doing GNC (guidance, navigation, and control) to have a PhD or two in control theory to make sure you get things right.
Most aerospace engineers with a GNC background know a lot about Kalmam filters.
