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,

Biologically inspired bearing-only navigation and tracking

2007 46th IEEE Conference on Decision and Control, 2007
In this paper we develop controllers that are used for the control of individual or groups of vehicles based only on sensors that provide bearing information. Our inspiration is derived from the observation that many ant species use landmark retinal positions to navigate without having any range information.

Optimal Landmark Selection for Bearing-Only Navigation

Proceedings of the Advances in Robotics 2019, 2019
Bearing-only navigation, using landmark information, is a well-researched area, with applications ranging from mapping an environment to reaching a known target position. Robot pose localization using bearing-only measurements is highly affected by the locations of surrounding landmarks, from which angular readings can be obtained via feature ...

Nonlinear pseudo-measurement filtering for in-orbit bearings-only navigation

IEEE Transactions on Aerospace and Electronic Systems, 2015
In-orbit rendezvous is a key enabling technology for many space missions that already enjoys significant heritage. However, complex hardware is generally required in order to measure the relative range. Achieving rendezvous employing only bearing/angle measurements would simplify the relative navigation hardware currently required, increasing ...

Finding Bearing in Robot Navigation with the Use of the Kalman Filter

Solid State Phenomena, 2013
In robotic systems navigation, it is necessary to determine the direction, in which the local coordinate system of a robot is to be turned in regards to the reference, global system. That direction from mathematical point of view is the rotation along one axis of the reference system, such that the reference system coincides with the local system ...

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

Linear bearing device as a solution for optical navigation of fine needle procedures

Technology and Health Care, 2010
Background: Optical navigation of needles < 1 mm diameter remains a challenging task. Bending of these tools is the limiting factor. Objective: To use a conventional optical navigation system for interventional fine needle procedures. Materials and methods: A novel custom-made device was constructed to guide the needle in the direction of the planned ...
