Abstract:Based on the highly successful application of quaternions for attitude estimation, this paper proposes an approach to position, velocity and attitude estimation for Micro Aerial Vehicles(MAVs) using dual quaternions. The states are represented in dual quaternion and time continuous states propagation model are derived via dual quaternion time update equation. At the same time, the error propagation equations based on additive error model is derived and implemented to fuse data from multiple sensors using Kalma… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
