Abstract
The Kalman filtering technique can be used to improve estimates of angular velocity (in a strapped-down navigation system) using angular increment (rate integral) data. A simple, second-order, constant coefficient digital filter can yield significant improvement for a very high or a very low noise-to-signal ratio = 4 σθ/σαT2, where σθ is the rms noise in measuring angular increments, σαis the rms angular acceleration, and T is the sampling time. For, ≈ 1, the filter affords negligible performance improvement.
