Efficient Rigid Body Localization based on Euclidean Distance Matrix Completion for AGV Positioning under Harsh Environment
Mounting multiple tags at different positions of the AGV to collect more TOFs is a feasible solution to tackle this difficulty.
A priori knowledge-free fast positioning approach for BeiDou receivers
In order to realize fast positioning during a cold or warm start in a GNSS receiver, the existing approaches require an initial estimation of position and time or require a number of computational steps to recover the full pseudorange information from fractional pseudoranges and then compute the position solution.
Robust Vehicle Positioning based on Multi-Epoch and Multi-Antenna TOAs in Harsh Environments
For radio-based time-of-arrival (TOA) positioning systems applied in harsh environments, obstacles in the surroundings and on the vehicle itself will block the signals from the anchors, reduce the number of available TOA measurements and thus degrade the localization performance.
Sequential Doppler Shift based Optimal Localization and Synchronization with TOA
In this paper, we develop a new optimal LAS method in the TDBS, namely LAS-SDT, by taking advantage of the sequential Doppler shift and TOA measurements.
Closed-form Two-way TOA Localization and Synchronization for User Devices with Motion and Clock Drift
Numerical results in a 3D scenario verify the theoretical analysis that the estimation accuracy of the new CFTWLAS method reaches CRLB in the presented experiments when the number of the ANs is large, the geometry is appropriate, and the noise is small.
Sequential TOA-Based Moving Target Localization in Multi-Agent Networks
Localizing moving targets in unknown harsh environments has always been a severe challenge.
A New TOA Localization and Synchronization System with Virtually Synchronized Periodic Asymmetric Ranging Network
In this article, we design a new time-of-arrival (TOA) system for simultaneous user device (UD) localization and synchronization with a periodic asymmetric ranging network, namely PARN.
Semidefinite Programming Two-way TOA Localization for User Devices with Motion and Clock Drift
In two-way time-of-arrival (TOA) systems, a user device (UD) obtains its position by round-trip communications to a number of anchor nodes (ANs) at known locations.
New Closed-form Joint Localization and Synchronization using Sequential One-way TOAs
Compared with the conventional iterative method, the proposed new CFJLAS method does not require initialization, obtains the optimal solution under the small noise condition, and has a low computational complexity.
Optimal Localization with Sequential Pseudorange Measurements for Moving Users in a Time Division Broadcast Positioning System
We show that the LSPM-D is a special case of the LSPM-KVD when the UD is stationary with zero velocity.
A Closed-form Localization Method Utilizing Pseudorange Measurements from Two Non-synchronized Positioning Systems
Numerical results verify the theoretical analysis on positioning accuracy, and show that the new CDL method has superior performance over the state-of-the-art closed-form method.
Optimal Two-way TOA Localization and Synchronization for Moving User Devices with Clock Drift
We show that the conventional two-way TOA method is a special case of the TWLAS when the UD is stationary, and the TWLAS has high estimation accuracy than the conventional one-way TOA method.
