Abstract: This paper reviews the author's previous work on free-running timescales based on Kalman filters that act upon clock comparisons. The natural Kalman clock ensemble algorithm tends to optimize long-term timescale stability at the expense of short-term stability.

Web12 de abr. de 2024 · In order to filter out the noisy measurement, we used a Kalman filter and showed that it provides a good estimate when the initial condition of theta is small. However, when we increased the value of theta to 90 degrees, we couldn’t estimate accurately, because the pendulum model acts nonlinearly for larger values of theta. Web5 de fev. de 2024 · Kalman filters are widely used for estimating the state of a system based on noisy or inaccurate sensor readings, for example in the control and navigation of vehicles or robots.

Web18 de jun. de 2024 · There are multiple versions of the Kalman filter. The idea behind the filter is this: You keep track of a vector of states of the system (i.e. position, speed, acceleration and noise) and update it for each new data. When post-processing data you can initialize de filter on a forward pass and then use the backwards for estimation.
