A new approach for modeling correlated Gaussian errors using frequency domain overbounding

S Langel, OG Crespillo… - 2020 IEEE/ION Position …, 2020 - ieeexplore.ieee.org
This paper presents a new method to overbound Kalman filter (KF) based estimate error
distributions in the presence of uncertain, time-correlated noise. Each noise component is a zero…

Overbounding the effect of uncertain Gauss‐Markov noise in Kalman filtering

S Langel, O Garcia Crespillo, M Joerger - Navigation, 2021 - Wiley Online Library
Prior work established a model for uncertain Gauss‐Markov (GM) noise that is guaranteed
to produce a Kalman filter (KF) covariance matrix that overbounds the estimate error …
