Bat target tracking strategies for prey interception
Communicative & Integrative Biology, 2021 Insectivorous bats capture their prey in flight with impressive success. They rely on the echoes of their own ultrasonic vocalization that yield acoustic snapshots, which enable target tracking on a rapid time scale.

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 ...

Characterizing an Air-Bearing Testbed for Simulating Spacecraft Dynamics and Control
Aerospace, 2022 Ground-based testbeds play a critical role in developing and testing different methods of spacecraft dynamics and control. To find the dynamic behavior in such an air-bearing testbed, a detailed characterization of the testbed must be provided via ...

A novel Technique for Improving the Angular Accuracy of Doppler VOR Receivers [PDF]
Advances in Radio Science, 2021 Doppler VOR (D-VOR) transmitters are used as navigation aids in aviation. They transmit an omnidirectional phase reference in an amplitude-modulated (AM) sideband and directional phase information on a frequency-modulated (FM) subcarrier.

Modern Solar Navigation Techniques
Groundings, 2023 Navigation by sea has proven difficult due to the absence of distinct markers for guidance. One solution for longer journeys was to track the position of celestial bodies as a navigational method, which has become more reliable as mathematical models ...

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 ...
