Journal ArticleDOI
Cooperative localization for autonomous underwater vehicles
James C. Preisig,Alexander Bahr +1 more
TL;DR: An algorithm for distributed acoustic navigation for Autonomous Underwater Vehicles that is computationally efficient, meets the strict bandwidth requirements of available AUV modems, and has potential to scale well to networks of large numbers of vehicles.
Book ChapterDOI
Cooperative Localization for Autonomous Underwater Vehicles
Alexander Bahr,John J. Leonard +1 more
TL;DR: An algorithm for distributed acoustic navigation for A utonomous Underwater Vehicles (AUVs) that is computationally efficient, meets the stric t bandwidth requirements of available AUV modems, and has potential to scale well to networks of large numbers of vehicles.
Proceedings ArticleDOI
Consistent cooperative localization
TL;DR: A technique for the consistent cooperative localization of multiple AUVs performing mobile trilateration is presented, which keeps conservative covariance bounds whereas state estimates obtained with the naive approach become overconfident and diverge.
Book ChapterDOI
Autonomous Underwater Vehicle Navigation
John J. Leonard,Alexander Bahr +1 more
TL;DR: This chapter surveys the problem of navigation for autonomous underwater vehicles (AUV s) and advances in algorithms such as simultaneous localization and mapping, and cooperative navigation have enabled dramatic improvements in the navigation capabilities of AUVs.
Proceedings ArticleDOI
Experiments in moving baseline navigation using autonomous surface craft
J. Curcio,John J. Leonard,J. Vaganay,A. Patrikalakis,Alexander Bahr,David Battle,Henrik Schmidt,M. Grund +7 more
TL;DR: A series of experiments that utilize autonomous surface craft, equiped with undersea acoustic modems, GPS, and 802.11b wireless Ethernet communications, to acquire data and develop software for cooperative localization of distributed vehicle networks are described.
