Determination of the reference point of a radio telescope using a multilateration-based coordinate measurement prototype

, 2023
International audienceA measurement campaign was carried out at the Geodetic Observatory Wettzell in order to determine the reference point of a radio telescope used for Very Long Baseline Interferometry (VLBI) at better than 1 mm.

Improvement of Ultrasound-Based Localization System Using Sine Wave Detector and CAN Network

Journal of Sensor and Actuator Networks, 2017
This paper presents an improved indoor localization system based on radio frequency (RF) and ultrasonic signals, which we named the SNSH system. This system is composed of a transmitter mounted in a mobile target and a series of receiver nodes that are ...

Insights into Corncrake (Crex crex) movements in a fragmented agricultural landscape using bioacoustics with implications for nature conservation strategies

Conservation Science and Practice, Volume 7, Issue 1, January 2025.
A noninvasive bioacoustics approach was used to study corncrake movements in a fragmented Irish agricultural landscape. We found that males moved an average of 415 m within a season and 375 m between years. Landscape features such as connectivity and suitable habitat area influenced their movements.

Specification of Sensing Coverage Zones in Two‐Dimensional Acoustic Target Localization

International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.
Target localization (positioning) by the time difference of arrival (TDoA) using previously localized wireless sensor nodes has wide applications. Three‐degree sensing coverage cannot calculate accurate spatial‐temporal information of the target object in two‐dimensional acoustic positioning.

APOTSA: Anchor placement optimisation using discrete Tabu search algorithm for area‐based localisation

IET Wireless Sensor Systems, Volume 14, Issue 6, Page 427-440, December 2024.
The authors present APOTSA, a novel algorithm for optimising anchor placement in indoor localisation systems, aiming to improve accuracy and reduce execution time. The approach APOTSA applies the Tabu search algorithm to minimise the expected residence area for better localisation.

A Review of Linear Multilateration Techniques and Applications

IEEE Access
In multilateration, distances between an unknown location and several known points are used to determine the location of the unknown point. Papers on algorithms for multilateration, such as time of arrival (TOA), time difference of arrival (TDOA), and ...
