3D TDOA Emitter Localization Using Conic Approximation [PDF]
Sensors, 2023 This paper develops a new time difference of arrival (TDOA) emitter localization algorithm in the 3D space, employing conic approximations of hyperboloids associated with TDOA measurements. TDOA measurements are first converted to 1D angle of arrival (1D-

Quantum Ranging Enhanced TDoA Localization [PDF]
ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)Localization is critical to numerous applications. The performance of classical localization protocols is limited by the specific form of distance information and suffer from considerable ranging errors. This paper foresees a new opportunity by utilizing the exceptional property of entangled quantum states to measure a linear combination of target ...

Compass Aided TDoA Tracking in LoRaWAN networks [PDF]
2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020 LoRWAN nodes can be localized using the TDoA (Time Difference of Arrival) approach. A big advantage is that the geo-location does not consume a lot of energy when compared to GPS approaches. Depending on the use case, the accuracy of the geo-localization (200m) might be a disadvantage.

Multi-TDOA Location Algorithm for Three Satellites TDOA Passive Location System [PDF]
Journal of Radars, 2012 Location precision of radiant source is the primary performance of passive location system, and how to improve location precision is an important problem which always attracts attention. In three satellites TDOA (Time Difference Of Arrival) passive location system, location precision of single pulse location is limited by the error of TDOA measure. For

On frequency domain models for TDOA estimation [PDF]
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015 Time-difference-of-arrival (TDOA) estimation is an important problem in many microphone signal processing applications. Traditionally, this problem is solved by using a cross-correlation method, but in this paper we show that the cross-correlation method is actually a restricted special case of a much more general method.
