Two-Filter Adaptive Gaussian Mixture Smoothing for Nonlinear Systems
Benjamin Schneiderheinze, Andrea De Vittori, Keith A. LeGrand +1
Space object tracking poses challenging estimation problems due to the significantly non-Gaussian distributions that can arise, particularly under highly nonlinear dynamics or duri…

Covariance Square Root Second-Order Mapping
Keith A. LeGrand, Braden Hastings, Jackson Kulik
In recursive state estimation, numerical error can play a major role in an algorithm's overall performance and reliability. Roundoff errors due to finite precision arithmetic can v…
