If your only sensor is broken and tells you nothing, then your system is unobservable with such a sensor and the only thing you can do is propagate your initial uncertainty through the dynamics. The Kalman filter will do exactly that in this case.
- rcxdude 3y agonot if you incorrectly estimate that the broken sensor has zero variance. In that case the kalman filter will discard all the other information and trust it completely. I think that's the point the poster is making (the article uses a somewhat naive estimate of variance)
