A two‐stage iterative method for short‐wave source localisation

open access: yesIET Radar, Sonar & Navigation, 2023
Short‐wave source localisation has an important role in many fields. A two‐stage iterative algorithm is proposed based on the ionospheric virtual height (IVH) model using the direction of arrival (DOA) and time difference of arrival (TDOA) measurements ...

Asymptotic Performance of TDOA Estimation Using Satellites

open access: yesIEEE Transactions on Signal Processing, 2022
We present novel lower bounds on the localization error using a network of satellites randomly deployed on a sphere around Earth. Our new analysis approach characterizes the localization performance by its asymptotic behavior as the number of satellites gets large while assuming a dense network.

TDOA based geolocation using IRLS algorithm [PDF]

open access: yes2017 International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS), 2017
The geolocation method using the wireless signal processing system is widely used in many industrial areas. The time difference of arrival (TDOA) method is one of the most commonly used geolocation methods. The TDOA signal based geolocation system can estimate the position of a mobile object by using at least three base stations in two dimensional ...

Necessary and Sufficient Conditions for Observability of SLAM-Based TDOA Sensor Array Calibration and Source Localization

open access: yesIEEE Transactions on robotics, 2021
Sensor array-based systems, which adopt time difference of arrival (TDOA) measurements among the sensors, have found many robotic applications. However, for existing frameworks and systems to be useful, the sensor array needs to be calibrated accurately.

A New Method of D-TDOA Time Measurement Based on RTT

open access: yesMATEC Web of Conferences, 2018
In this paper, a novel difference-time difference of arrival (D-TDOA) time measurement method based on round-trip transmission (RTT) is proposed. The accuracy of time measurement is critical for high accuracy positioning, yet the traditional time ...
