Title

Robust, Terrain-Aided Landing Navigation through Decentralized Fusion and Random Finite Sets

Abstract

This paper explores the use of simultaneous localization and mapping with random finites sets to process terrain camera data and augment traditional Kalman filter-based navigation tools. Enabled by new theoretical developments, the presented methods employ both consider parameters and square-root factors of covariance in the interest of producing a practical, numerically stable navigation algorithm. Additionally, a model is presented for a data-driven learning procedure that permits observations of previously unexplored terrain to be instantiated into the filter and improve subsequent navigation estimates. The proposed techniques are evaluated in a simulated lunar descent scenario, and a Monte Carlo analysis confirms the statistical consistency of the described methods.
