Conjunction analysis is the study of possible collisions between objects in space, and is aimed at reducing the number of collisions between manmade objects and debris orbiting the Earth. It has been found that kd-tree based methods significantly reduce computational cost while obtaining comparable results. This research extends the applicability of the tree-based approach by accounting for non-Gaussian uncertainties, as well as correcting the probabilistic nearest- neighbor search. Employing these modifications, it is expected that the favorable computational efficiency of the tree-based approach is maintained, while extending the applicability of the proposed method.
