Simple yet stable bearing‐only navigation [PDF]
Journal of Field Robotics, 2010 AbstractThis article describes a simple monocular navigation system for a mobile robot based on the map‐and‐replay technique. The presented method is robust and easy to implement and does not require sensor calibration or structured environment, and its computational complexity is independent of the environment size.

Bearing-Only Navigation With Field of View Constraints [PDF]
IEEE Control Systems Letters, 2021 This paper addresses the problem of navigation using only relative direction measurements (i.e., relative distances are unknown) under field of view constraints. We present a novel navigation vector field for the bearing-based visual homing problem with respect to static visual landmarks in 2-D and 3-D environments.

Observability-enhanced proportional navigation guidance with bearings-only measurements [PDF]
The Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1999 AbstractWe analyse the performance of the additive observable proportional navigation guidance system, which is well-suited for low-cost homing missiles with bearings-only measurements. Closed-form solutions are derived for both manoeuvring and non-manoeuvring targets.

Show me the way to Monte Carlo: density-based trajectory navigation [PDF]
, 2007 We demonstrate the use of uncertain prediction in a system for pedestrian navigation via audio with a combination of Global Positioning System data, a music player, inertial sensing, magnetic bearing data and Monte Carlo sampling for a density following ...

GpsTunes: controlling navigation via audio feedback [PDF]
, 2005 We combine the functionality of a mobile Global Positioning System (GPS) with that of an MP3 player, implemented on a PocketPC, to produce a handheld system capable of guiding a user to their desired target location via continuously adapted music ...

Acoustic positioning and tracking in Portsmouth Harbour, New Hampshire [PDF]
, 2007 Portsmouth Harbor, New Hampshire, is frequently used as a testing area for multibeam and sidescan sonars, and is the location of numerous ground-truthing studies. Having the ability to accurately position underwater sensors is an important aspect of this

Optimal Trajectories for Homing Navigation with Bearing Measurements
IFAC Proceedings Volumes, 2008 In this paper we examine the geometry of a number of navigation schemes for guiding a pursuer from a fixed initial position to a final target position. We explicitly characterize the optimal pursuer trajectories for the given problems in terms of minimizing the error in an unbiased estimate of the target position from successive bearing measurements ...

Evidence consistent with the multiple-bearings hypothesis from human virtual landmark-based navigation [PDF]
Frontiers in Psychology, 2015 One approach to explaining the conditions under which additional landmarks will be learned or ignored relates to the nature of the information provided by the landmarks (i.e., distance versus bearings). In the current experiment, we tested the ability of such an approach to explain the search behavior of human participants in a virtual landmark-based ...
