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,

Autonomous navigation using received signal strength and bearing-only pseudogradient interpolation

Robotics and Autonomous Systems, 2016
Autonomous mobile robots (AMRs) interacting with an a priori distributed wireless sensor network (WSN) in a region can address the three-tier challenge of navigating in unknown environments: (i) identifying target locations, (ii) planning paths to the targets, and (iii) efficiently executing the navigation paths to the targets.

Trajectory characterizations for a discrete-time bearing-only navigation strategy

2008 16th Mediterranean Conference on Control and Automation, 2008
In this paper we explore the geometry of a particular navigation scheme which guides a pursuer from a fixed initial position to a given fixed final position using a one-step look ahead strategy and using only bearing measurements. We explicitly characterize the optimal trajectories for the problem in terms of the Cramer-Rao bound such that the derived ...

A Navigation system of mobile robot based on bearing measurements of beacons

2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017
The problem of navigation and control of movement of wheeled mobile robot by bearing of the reference beacons is considered. The quality criteria of controllable motion of such robots are revealed, the formalism of nonholonomic mechanics used for constructing their mathematical models is briefly considered.

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 ...
