A new bearing-only navigation law

2017 17th International Conference on Control, Automation and Systems (ICCAS), 2017
This paper proposes a new bearing-only control law which can be used for autonomous navigation task. We firstly compare the proposed control law with a commonly used control law in the literature when the agent navigates with only one beacon. Second, we prove that if there are two or more beacons, the agent can almost globally asymptotically reaches ...

GES source localization and navigation based on discrete-time bearing measurements

52nd IEEE Conference on Decision and Control, 2013
This paper addresses the problems of source localization and navigation based on discrete-time single direction measurements, in 3-D, in addition to relative velocity readings. For source localization, an agent aims at estimating the position of a source relative to itself, while for navigation the agents aims to estimate its own position assuming that

A study on cooperative navigation of AUVs based on bearing measurements

OCEANS 2021: San Diego – Porto, 2021
In this work, two cooperative navigation solutions based on the extended Kalman filter are described. One of these is a centralized solution and the other is fully decentralized, taking full advantage of the benefits that come with decentralization, such

Navigation systems based on multiple bearing measurements

IEEE Transactions on Aerospace and Electronic Systems, 2015
This paper presents two navigation filters based on multiple bearing measurements. In the first, the state is augmented and an equivalent linear system is derived, while in the second the output of the system is modified in such a way that the resulting system is linear. In both cases, the design of a filtering solution relies on linear systems theory,
